Hello, I'm running the most recent version of Parallels 6 for Mac with a Win XP virtual machine. I previously had no trouble using USB devices on the Windows side, but am no longer able to do so. In device manager, both USB drivers have yellow exclamation points: Intel(R) 82801FB/FBM USB Universal Host Controller - 2658 Intel(R) 82801FB/FBM USB2 Enhanced Host Controller - 265C. I've tried updating the drivers, uninstalling and reinstalling, disabling and re-enabling the USB controller via the parallels configuration page, but nothing has helped. I've tried connecting flashdrives and my TI-84 calculators, but nothing appears on the windows side.
