ABIT KT7A motherboard running an XP1600 chip
1Gb RAM, at least 4Gb HDD space on primary drive
Windows XP, SP1
My USB ports all just suddenly stopped working; no devices connected to them actually function. One of the devices is a four-port hub, which has a light on top (to tell you it’s working) which still comes on whenever I connect it, and my optical mouse (Logitech MX310) lights up when I connect that (but won’t actually move the mouse cursor), which suggests to me that the ports are still passing energy through to connected devices, without actually letting the work (if that makes sense). If I attach a USB-to-PS2 connector on the mouse, and plug it in like that, it works fine. I tried another USB mouse on the machine, but that doesn’t work either. My ADSL modem (Alcatel Speedtouch USB) just flashes its ‘USB’ light if I connect it, but never actually seems to initialise, and doesn’t show up at all in Device Manager (the modem’s System Tray icon is sort of greyed out and pops up with ‘Modem not connected’ if I hover my mouse cursor over it). I tried the modem on another machine and it does the same, so that might just be dead (was wondering if that dying might have taken the USB controller with it).
After various rebooting tests, with and without any devices attached, I uninstalled all the USB connection devices (which were all showing as ‘This device is working properly’) from Device Manager, then ran a ‘Add New Hardware’ sweep and it found them all, installed the drivers and reported ‘This device is working properly’ in each case.
I connected a secondary USB port connector to my motherboard, giving me two separate ports, and tried the same tests with that, however, it yields the same results.
