Hello,
this is my first try here, so bare with me, if I may not get it right.
I had the latest VM 4.0.r running with Win XP and installed Win 7 parallel to it. SInce USB didnot work I deinstalled XP but still it doesnot work.
I installed the guest addition correctly and even tried an older version for I guess this it what doesnot work.
Of course I added the USB devices in the settings menu of VM etc.
When I click on the USB device at the lower right corner of the frame of the guest, it indicates that the USB device is recogniced and has a tag. The yellow context field says "captured" with all the USB devices I tried. There is also the sound of Win7 stating that the USB devices are plugged in or out. Yet, during installation of the drivers the installation always stops, whatever USB device I take and tells that it cannot finish installation due to some unknow problem. In the device mananger of Windows comes a yellow triangle saying that the USB device cannot be installed. Yet there are 2 USB drivers installed and working, namely the standard openHCD USB-Hostcontroller and the USB Roothub.

The Apple IR device has a tag, the Apple USB host controller doesnot and also gives a failure message when I want to put a tag to it, saying it cannot attach the unknown USB device to Win7.
Under XP everything went well with the same host OS and VM and Guestaddition.
Any idea?
Thank you for your help in advance
Philip
