    USB Problems (WIN XPP)

    I have a couple of usb ports on the front of my box. When I plug a card reader into one of the usb ports, I can hear the chime that let's me know the system has found the new device. I mouse over to the Explorer and open the card and move digital photos to my hard drive - no problem.

    Then I realize that I've lost my keyboard, it no longer responds, NOTHING. Not even pulling the card reader from the usb port will help. I've totally lost the keyboard for this session and the only way to get it back is to reboot. What a pain!

    If I boot with the card reader already in the slot, then everything works. But that's not the way usb is supposed to function. I should be able to plug and unplug without rebooting. Any ideas?

    BTW, my mouse and keyboard are usb and plugged into the rear of the box.

    Re: USB Problems (WIN XPP)

    It actually sounds like a hardware problem....what kind of hardware is this? Dell, Compaq, homegrown, etc? The first thing I would try is to look and see if there is a USB filter driver or something similar for the system. I had a multitude of problems with USB devices that were solved with the Via USB driver (which applies to AMD systems only, I believe, and not in all cases).

    Was this an upgrade of XP, clean install, or an OEM preload?

    It's 100% home made! WinXPP from the very start, not an upgrade. It is an Intel cpu and the intel 850 chipset on the mb. MS Office keyboard. I know all the connections are good because everything works fine if you connect all the devices before powering up. I think I can resolve the issue by using the ps2 connection for the kybd vs. usb. It doesn't fix the problem but it will bypass it!

    Ricky, Do you have the most current BIOS? Are you up to date on XP patches? Does this happen immediately? After hibernation or standby? Most current keyboard driver (just available on MS site yesterday)?

    This should probably be moved to the hardware board as I believe Mark is correct (this is likely not a WinXP problem).

    The keybd loses functionality immediately when the card reader chimes in...there is no delay.

    I do keep Windows current with all the patches and updates. I had not heard of the keybd update but I'm going after it in just a moment. The motherboard is an Abit Th7-ll RAID with intel chipsets and usb controllers. I checked the Intel site but no updates were offered for the chipsets, in fact, it said that WinXp users should just use Windows drivers.

    I checked the Abit site and there was an update available for the bios. It's hard to tell exactly what the upgrade accomplishes...check out the readme file. IS this ridiculous or what. I've never heard of openeing the box and clearing the CMOS as part of flashing the BIOS. Very strange and I haven't done it yet!

    This is a copy and paste of the readme file. When I misspell something, I understand; but when there are misspelled words in an instruction for updating bios, that's hard to fathom...
    <hr><font color=blue>[b]1. How to upgrade BIOS:

    a. Boot into MS-DOS or "Safe mode and command prompt" if you are using
    Windows95/98
    b. Run "th7h7c.exe" to extract all files.
    c. Run "runme.bat"

    *** Please notice that we suggest you flashing the bios with switches

    "/py /sn /cd /cp /cc /cks /R" or by "runme.bat".

    2.After BIOS updated, pull off the power core and then clear the CMOS data
    via jumper before restarting system please.<hr>

    English as a "second language!" Doesn't surprise - having bought MUCH computer hardware or software produced "offshore." Sounds about like the way I speak German!

    Re: USB Problems (WIN XPP)

    We purchased a bunch of PC's at work a couple years ago with 2 rear USB, and 2 front USB ports. I recall having a similar problem, but in our case, the front ports were a "nice to have", that only worked if the rear ports were empty. The vendor assured us this was by design, and couldn't be corrected.

    It was a huge problem in our eyes, as only one user (of 500 current PC installations) uses more than 2 USB ports on their computer. We simply purchased a hub for his devices.

    Yep! My German probably ain't real good, either. I just get so irritated when something so simple is made so complicated. It's akin to having to disassemble an entire engine just to change a spark plug! <img src=/S/brickwall.gif border=0 alt=brickwall width=25 height=15>

    Re: USB Problems (WIN XPP)

    Chris, that could be the issue here as well. Two in the back and two in the front. I sure thought they would work independantly of each other. The front usb (case) ports are connected to the mb just as you would connect the power button, l.e.d. lights, etc.

    I've moved my keyboard to a serial connector, now the only usb being used from the back is for a printer. I haven't checked yet but I bet there won't be any problems now when I use the front usb for the card reader. It's not a fix, it's just a work-a-round.
