Re: [Xen-devel] usbpassthrough of xen-4.1.2

[Qian Hu <qianhu2011@xxxxxxxxx>]

More infomation:

I have tried the USB 2.0 Mass Storage by  by specifying "usb = 1" and "usbdevice = host:xxxx:yyyy" 

But I can't use it in the guest OS(win7). It is listed in the device manager, and the driver is OK, but can't start.

I can only find the message  "The device cannot start(code 10)".

I am sorry I haven't tried the linux guest.

You need to give more details. How did it not work? Did it work in Linux?

Right, that is b/c it would only work with Linux.

Try first an Linux HVM guest and pass in. See what works and what does not.
