Hi, I use parallels 8 with windows XP. I have only one problem with parallels. When I connect a usb interface 'USB - CAN', select windows Xp for use it. After in Windows I don't find the peripheral in the system, so I can not install the driver and I can not use it. In parallels desktop I select 'Devices', 'USB', and I read the device and select it with click mouse, but windows not read the device. I use many other usb peripheral and all work correctly. Help Thank you
