I heavily use the functional buttons of my Thinkpad mouse to copy/paste. Its driver is ok in boot camp win7. However, in virtual win7, the system can't recognise the device name. I tried parallels setting to make sure that the usb device is connected to parallels rather than to mac.
Hi Xiaoxu, Please follow the steps suggested at, http://kb.parallels.com/111725. Also after connecting the USB Device to the Virtual Machine. At the top of your screen click on Devices >> External Device >> Check if you are able to find the USB device >> If you are able to find, please click on the device and check if it is getting detected.
