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?

I just went and changed the driver to a generic usb driver (specifically the "Standard Universal PCI to USB Host Controller"... lol... Standard Universal), and it all works now. I copied files from my CF card while using my usb mouse, syncing my Casio, and watching video on my webcam. FYI, the Generic driver DOES use the usbUchi.sys, but I'm just happy that it works. This is on my KX133 board, I haven't tried it on my KT133, and probably won't for a bit (no PSU in it for now), but it is hopeful!

Maybe somebody (I) should try to extract the 2k drivers...

Mine is not. The KA7 is 8x100, and the A7V is 8.5x100 It really just astonishes me that it all worked fine under 2k, and it almost seems like it's just the drivers.
