I'm using XP build 2600 (RTM).
Whenever I do anything "high bandwidth" (IE use my web cam, sometimes when syncing my pda, or copying files from a cf card) my usb drops out. I've tried this with both a KX133 and a KT133 board with the same results. Here's what I have:
Logitech Mouseman Optical (4 buttons)
Intel Webcam (White, CS330, or as windows calls, it Video Cam III)
Casio Cassiopeia E-125
Sandisk CF reader
The KX133 board is an Abit KA7-100, and all the devices are connected via a hub. On the KT133 board, an Asus A7V, they were all connected via the provided usb ports. Once I lose the usb, the only way to restore it is to reboot or disable and re-enable the usb controller. I tried the using different webcam drivers for the longest time to no avail, and everything works under 2k or me prefectly with an identical configuration.
My guess is that the problem lies in the via usb drivers, but I'm at a loss. Has anybody had any similar problems or have any ideas?
