Hi Everyone! This is my first post to MacRumors. I've searched the forums and Google for help on my problem but didn't find a solution. I hope the experts here can help me I've just installed Windows 7 64-bit via bootcamp on my new Mac Pro running Snow Leopard. The Windows 7 install went fine, and the 64-bit drivers from Apples Snow Leopard DVD installed without any problems. Everything seems to be working fine. I plugged in a USB flash drive (FAT32 format) while running Windows 7 and it was detected okay. I copied some files off it and at some point rebooted the Mac Pro leaving the USB flash drive plugged in. When Windows 7 restarted I discovered an "unknown device" listed under "USB controllers" in Windows' Device Manager. I noticed that the USB flash key was not visible in Windows Explorer (and its activity light was not on). I removed the flash drive, and the "unknown device" disappeared from Device Manager. I could then plug the USB flash drive back in and it was properly recognized. The problem seems to be that if Windows boots with a USB harddrive (or at least flash drive) connected, it is not properly detected by Windows and I need to unplug and replug it to make it work. Does anyone have comments on this? Any news or ideas would be great to try and resolve the problem. Thanks!
