Ok, I have this computer here... It has windows xp with service pack 1
installed. It had onboard USB 2.0 ports that were not recognized by Windows
XP. THe other USB 1.1 ports were. Upgrading to Service Pack 1 is
supposed to add USB 2.0 support. It didnt. So, i found offical USB drivers
from microsoft for windows XP. I installed them and then the usb 2.0 ports
were recognized and supported.
The problem is this - Before the driver upgrade, any usb device would work
on any port. AFTER the upgrade, only the usb mouse will work on any port.
Plugging in ANY other USB device will make the computer instantly freeze.
Even if i unplug the mouse and plug into the port the mouse was in, it will
freeze. If you reboot, it will freeze at the Windows XP logo screen. If i
unplug the usb device and plug the mouse back in, everything works again.
Everything i have found on the net about USB freezes say that its a conflict
issue. One USB controller shares an IRQ with the video card, the other
shares with the hard drive controller. The problem is - You cant change
them! Nowhere in the BIOS will it let you change them and in the resources
tab of the device properties, all the stuff to change settings is greyed
out.
Any ideas?
