cc: ~wymette/drivers AptivaNotes/USBnotes USB Supplement Update Alice Forum Regular posted 07-13-2001 12:17 PM I did not have to do anything for USB to work on my 2140 L5H. Those with older 2140 systems such as the L31 may need to enable USB in the Setup Utility (under I/O ports) but mine was already enabled. Additionally, my existing version of the USB was 4.03.1214 as opposed to older systems that came with the 1212 version and need the IBM's USB Supplement Update. To see what version of USB you have installed, follow these instructions (from HP's website, regarding their USB ScanJet 5200c): Determining correct version of Microsoft Windows 95 for the USB scanner (snip) 1. Open the Explorer. 2. Open the system folder under the Windows folder and look for the files listed below. All of these files should be version 4.03.1214. 3. Check the version by selecting the file, clicking the right-mouse button, and clicking the properties menu item. 4. Click the version tab and check the version listed. If you do not have the correct version, contact your computer manufacturer to obtain the following four updated USB drivers: · USBD.SYS · USBHUB.SYS · OPENHCI.SYS · UHCD.SYS ============================================ It all doesn't matter though, unless your USB device syas it will work in Win95B. You have to check the manufacturer's documentation -many USB devices require Win98. ------------ NOTE: For OSR2 systems needing the USB Supplement Update, see http://www.pc.ibm.com/qtechinfo/PMYS-3PFNJW.html Aptiva - USB update for OSR2 preloaded systems (US) I do not believe that the USB Supplement Update available at IBM (Usbupdus.exe is the downloadable file containing usbsupp.exe) is necessary for MOST 2140/2142 or later systems. (I think the older 2140 systems ike the L31 may be the exception) Checking oemusb.exe, the equivalent, I've gathered, of usbsupp.exe, I have version 4.03.1214 in Windows\Options\Cabs. Checking individual files (see below) I have 1214 files. Using Qfecheck.exe, I have UPD970717R2, Windows USB Update, listed on my 2140 L5H, with updated file OPENHCI.sys ver 4.3.0.1214. Also checking for usbupd2.exe, the version I have in C:\Windows\Options\Cabs is 4.71.0728.0 This is actually an update to the USB Supplement. See http://www.walbeehm.com/win95upd.htmlfor more information about Windows 95 System Updates and usbupd2.exe. -------------- from Windows 95 System Updates http://www.walbeehm.com/win95upd.html : "There are at least two versions of usbsupp.exe. When looking at the file's version number (from its properties), you can tell the difference: One version has version number 4.03.1212, while the other has version number 4.03.1214. The problems I described above occurred with both versions. The following is a list of all the files contained within usbsupp.exe that differ between these two versions: DETROIT.INF OPENHCI.SYS UHCD.SYS USBCAMD.SYS USBD.SYS USBHUB.SYS VFWWDM.DRV VFWWDM32.DLL Microsoft does not offer usbsupp.exe on its site, but several major computer vendors do. If you would still like to try upgrading your OSR2 system to OSR2.1, here are some links to the latest usbsupp.exe (version 4.03.1214). To reduce the risk of virus-infected files, I only list links to sites of major vendors: From Dell: ftp://ftp1.us.dell.com/misc-d/USB.EXE In addition, IBM's site not only has the regular US-English version of this update available (usbupdus.exe), but also several localised versions: From IBM: ftp://ftp.pc.ibm.com/pub/pccbbs/aptiva/usbupdus.exe (American (US))" -------------- from http://www.compuclinic.com/osr2faq/index.html#USB 14 Mar 98 Does OSR2 support USB? No. There is an update, which can only be installed on top of OSR2, called "usbsupp.exe." This update is also known as "OSR2.1." It has been released to OEMs, and is also available in MSDN. This patch also contains the "Windows Driver Model" (WDM) update, which is necessary, so I'm told, for support of all features of the new AGP graphics adapters (only supported by the new LX chipset (Pentium II). Some of the newest AGP cards will not work properly unless this patch is installed. This update will only install on OSR2. There are two versions of this patch, 4.03.1212, and 4.03.1214. The latter version fixes some incompatibilities present in the former version. If you have the older version and it has caused problems, uninstall it and install the newer version. The older version is in the Other\Updates directory of the OSR2.1 CDROM, and the newer version is in the Other\Updates directory of the OSR2.5 CDROM. --------------------------- See http://www.walbeehm.com/win95updcontents.html#USBSUPP1212 - for 4.03.1212 files and http://www.walbeehm.com/win95updcontents.html#USBSUPP1214 -for 4.03.1214 files (My 2140 L5H has version 1214 files) AW --------------------------- (from http://www.walbeehm.com/win95upd.html Windows 95 System Updates) Contents of usbupd2.exe, USB Update files (this is the one I have AW) usbupd2.exe (UPD970717R2) ????-??-?? ??:??:?? 144096 4.71.728.0 (4.71.0728.0) 4.71.728.0 (4.71.0728.0) 1997-04-28 12:41:06 70608 ADVPACK.DLL 4.71.728.0 (4.71.0728.0) 4.71.728.0 (4.71.0728.0) 1997-07-17 12:14:00 31248 OPENHCI.SYS 4.3.0.1214 (4.03.1214) 4.3.0.1214 (4.03.1214) 1996-02-02 13:58:56 36352 QFECHECK.EXE 4.0.0.950 (4.00.950) 4.0.0.950 (4.00.950) 1996-01-26 15:52:02 8042 QFECHECK.HLP NONE (NONE) NONE (NONE) 1997-04-28 12:41:06 2272 W95INF16.DLL 4.71.704.0 (4.71.704.0) 4.71.704.0 (4.71.704.0) 1997-04-28 12:41:06 4608 W95INF32.DLL 4.71.16.0 (4.71.0016.0) 4.71.16.0 (4.71.0016.0) 1997-07-23 11:40:04 695 W95UPD2.INF NONE (NONE) NONE (NONE) --------------------------------------------------------------------- this is a newer version: usbupd2.exe ([no update code]) ????-??-?? ??:??:?? 365920 4.71.30.1 (4.71.0030.1) 4.71.30.1 (4.71.0030.1) 1997-07-17 06:43:26 31248 OPENHCI.SYS 4.3.0.1214 (4.03.1214) 4.3.0.1214 (4.03.1214) 1997-11-21 15:33:18 641 PATCH.INF NONE (NONE) NONE (NONE) 1997-08-13 16:57:34 39872 UHCD.SYS 4.3.0.1215 (4.03.1215) 4.3.0.1214 (4.03.1214) 1997-04-10 12:14:00 18240 USBD.SYS 4.3.0.1214 (4.03.1214) 4.3.0.1214 (4.03.1214) 1997-08-29 15:04:52 28448 USBHUB.SYS 4.3.0.1215 (4.03.1215) 4.3.0.1214 (4.03.1214) 1997-04-10 12:14:00 17072 VFWWDM.DRV 4.3.0.1214 (4.03.1214) 4.3.0.1214 (4.03.1214) 1997-04-10 12:14:00 49152 VFWWDM32.DLL 4.3.0.1214 (4.03.1214) 4.3.0.1214 (4.03.1214) 1997-09-23 09:51:18 427552 VMM.VXD 4.3.0.1216 (4.03.1216) 4.3.0.1214 (4.03.1214) ----------------------------------------------------------------------- Files Included with the USB Supplement in OSR2.1 and OSR2.5 The information in this article applies to: Microsoft Windows 95 OEM Service Release versions 2.1, 2.5 SUMMARY This article lists the files included with the Universal Serial Bus (USB) Supplement on the Windows 95 OEM Service Release 2.1 and 2.5 CD-ROM.

It wouldn't be a bad idea, given that it's not really just an update but a full USB Supplement for osr2 systems. ----------------------------------------------------------- Subject: Re:USB link Date: Sat, 20 Mar 1999 10:21:47 -0500 From: Wyman To: Janice Brooks Janice wrote: > Did you see this one? > > http://www.aesystems.com/usb_install.html Adding a USB driver in WIN95 SR2.1 2/8/98 AJE last updated 3/14/99 "When WIN95 is first installed into a PC, the USB driver isn't configured properly. The reason is simple enough - WIN95 didn't have the driver for it when it installed. If you bought a machine, and it is in this state, then the PC house was too lazy to configure it for you. It is that simple. It only takes ten minutes to load the drivers and test the USB port." _________ Looks like this is for cases where the USB Supplement wasn't installed initially, since it's a second step with OSR2.1 see http://pentium.intel.com/support/graphics/express3d/24513.htm _________ "The USB Supplement is not installed automatically with the installation of Windows 95 OSR2.0/2.1/2.5. The USBSUPP.EXE must be run separately. The USB supplement, USBSUPP.EXE, is ONLY available on the Microsoft Windows* 95 OEM Service Release 2.1 and 2.5 CD-ROM." ________ It's not on my Companion CD, I've checked before. IBM did install it. I don't show anything under 'other devices' in Device Manager. Under USB controller it lists 1)USB Root Hub, showing 'no resources used' 2)Standard Universal PCI to USB Host Controller, IRQ-11, I/O 300h-301fh Device Drivers : C:\Windows\System\uhcd.sys Microsoft Corp. ver 4.03.1214 C:\Windows\System\usbd.sys Microsoft Corp ver. 4.03.1214 also I have USB Supplement to OSR2 in Add/Remove. I wonder why the article didn't say to check for that? Heres where it gets confusing, since these instructions were written in cases where the USB Supplement was not installed by the oem: ____________ "Double click on the usbsupp icon. Follow the prompts to install the USB driver. You will see the following screen [asks to install USB]. Click YES and continue. If the USB driver has already been installed, you will see an error screen [says you must uninstall the USB or reinstall W95B or reboot] Don't worry about this screen if you see it. It just means the Microsoft USB drivers are already on the HD. Skip over the next few installation screens and reboot the PC. Otherwise the USB drivers will be installed into the C:\WINDOWS\SYSTEM directory, although you are never told this and have no control over it anyway. If it isn't already present, the USB driver will start to install. You must accept the license agreement and click YES." ___________ I guess they mean that if the usb drivers are already on the hard drive, abort the installation. One interesting thing, it says that, once the USB drivers are installed (this would be important if you uninstalled the USB Supplement, then ran the usbsupp.exe) and after you reboot: ____________ "WIN95 is not smart when it comes to new hardware installations. It will find the new USB hardware, but it will want to know where the drivers are. After clicking Finish on the above menu, it asks for the driver location. You will need to type in C:\WINDOWS\SYSTEM." ____________ So this is one case where, if windows asks you to insert the Windows CD Rom, you don't point it to Cabs, but to Windows\System, since that's where you installed the new drivers.

Lookes like uninstalling went badly. I was thinking to mention that, maybe the usb supplement can be reinstalled using oemsub.exe in cabs and then the update applied (or just to apply the update directly), but I'm afraid to suggest it in case it would make things worse. Alice ps, notice the versions of usbhub.sys mentioned? Looks like the one we have already is the version that will work (4.03.1214). --------------------------- Ntkern.vxd Error Topic: Missing NTKERN.VXD (1 of 2), Read 20 times Conf: Aptiva 2161 and 2162 From: Thomas Wassick Date: Thursday, March 11, 1999 11:28 PM Eastern Standard Time During an attempt to install the USB support upgrade listed on the 2162-S35 support page, it appears that my copy of NTKERN.VXD from the /windows/system/vmm32 directory got trashed, and when the machine boots, I get an error saying that it's missing. Can someone send me a copy of theirs from a Windows 95 OS2R2 system (4.00.950.B level)?? I think the date should be 8-24-96. Send it to [snip]@ibm.net or [snip]@us.ibm.com. The problem occurred when I was attempting to uninstall the current USB supplement from the Install / Remove programs menu. Since the new version indicates that I needed to remove the previous level first, I tried that. It seemed to start the uninstall, then the computer locked up and I was left with the missing file. And so now I can't uninstall the old version or install the newly downloaded version to get my USB suppport to the right level (our new digital camera wants USBHUB.SYS to be at 4.03.1214 and the currently installed version was 4.03.1213. Any hints on how to "fool" the system into installing the new version over what appears to be a partially installed old version (due to the lockup I'm guessing). Thanks! Topic: Missing NTKERN.VXD (2 of 2), Read 23 times Conf: Aptiva 2161 and 2162 From: Alice Wyman Date: Tuesday, March 16, 1999 03:22 PM Eastern Standard Time Hi, My friend and I were just talking the other day about whether or not you needed to Uninstall the USB Supplement from Add/Remove before running the usbsupp.exe file from the installation diskette. The usbupdus.txt file says, under HOW TO UNINSTALL THIS PRODUCT, "If for any reason you wish to reinstall the USB supplement, you must first uninstall any version currently on your system." However, IBM's instructions do not mention uninstalling the preloaded USB Supplement. Here's what I have in my notes about ntkern.vxd: Ntkern.vxd is a driver file for USB. It is created by another file called Usbsupp.exe...(snip) Simply double-click on the Usbsupp.exe file and it will automatically create Ntkern.vxd (along with a few other files required for USB) and place them in the proper directories. ---------------------------------- If there's still an entry in add/remove, I would try uninstalling again with things like the antivirus off. I wouldn't want to advise you to do anything, but it makes sense to me that the error message you're receiving will be cleared up when you install the USB update.

I believe it is in the \other\usb folder on the CD. version # ending in 1214 is more functional. Go to http://www.walbeehm.com/win95upd.html for more info on the update versions and where to find them if you don't have the CD. The reason you need the USBSUPP is that it contains a newer version of the memory manager, which is needed to use the VGARTD driver for DIME, in order to enable the features of AGP. So you need the VGARTD driver too. You also need to enable AGP in the BIOS, and enable USB there too. It's difficult to set this up after the fact, that is, after the system has been up a while. I ended up running my AGP card without using the features ( no great loss). It just runs like a PCI card, which is fine. But you need to enable AGP in the BIOS regardless. At least this is my understanding, after many posts at comp.sys.ibm.pc.hardware.chips It was posted under AGP and VIA chipset, I believe. Good luck....the Intel cards are much less forgiving or compatible than most, tho....may not work with the VIA chipset. What is your chipset/motherboard ?

Someone said there is a file called usbupd2.exe but I dont know where to find it. I need to update my USBUPD.EXE files from 4/97 to something newer to get the quickcam vc usb to work.... Could you help me out. Do you happen to have a file called: Usbhub.sys 4.03.1218 7/1/98 12:14am 28,528 bytes its in the windows/system directory I believe. Apparently that file is needed to get the quickcam vc USB version to work on win95. I cant get it to work on win95, are you running win95 or win98? No where on ms website do they have that new 4.03.1218 version for Usbhub.sys for download. can you email me the latest version of this file? Thanks George -------------- NOTE: regarding AGP, my ATI video driver has been updated to v 4.35-e20e, via Update Connector. The printout for the update says this driver version - Provides full AGP enablement and support for newer Aptivas (Rage Pro). After updating, in Device Manager, Display Adapters, ATI 3D Rage Pro, Properties, Diagnostics tab,Status button shows S/W Release Version 4.35-C20E ASIC Type 3D Rage Pro AGP 2X AW ------------- from ScanJet.txt: The setup instructions at http://www.hp.com/cgi-bin/cposupport/cspt/cds/dlvr.pl?lid=general&fid=bps03165&pid= say to install the software first, then attach the scanner to the pc, which is the reverse of what I would have expected.... I'll have to go into the Setup Utility first then to enable USB, if necessary, according to the HP support information. I rechecked my version of USB. It's 1214 on the files mentioned by the following, from http://www.hp.com/cposupport/scanners/support_doc/bps03174.html Determining correct version of Microsoft Windows 95 for the USB scanner (snip) 1. Open the Explorer. 2. Open the system folder under the Windows folder and look for the files listed below. All of these files should be version 4.03.1214. 3. Check the version by selecting the file, clicking the right-mouse button, and clicking the properties menu item. 4. Click the version tab and check the version listed. If you do not have the correct version, contact your computer manufacturer to obtain the following four updated USB drivers: · USBD.SYS · USBHUB.SYS · OPENHCI.SYS · UHCD.SYS ================== from my email=========================== Date: Fri, 29 Mar 2002 09:50:59 -0800 From: Emmanuel To: alice I read in your usb supplement update page about George Wang asking for usbhub.sys file version 4.03.1218. I happen to find a usb patch from the Toshiba site where it contains both uhcd.sys & usbhub.sys files w/ version 4.03.1218. Here's the exact url to get it: http://home.toshiba-tpc.com/sos/download.html?c=548&i=1879 (it's called the USB Shutdown fix). Ignore the usb95.exe patch I found from the HP support site. The usb shutdown update fixes a problem that Win95 hangs at the shutdown screen when a usb device is connected. If Mr. Wang is still using Win95b and looking for usbhub.sys v4.03.1218 tell him to get the patch from the Toshiba site. The usbupd2.exe file from ftp.compren.com he talked about no longer exists (and that ftp site also no longer works). =
