O2micro USB: VERR_NOT_SUPPORTED

[komma]

Hi,

I'm using VirtualBox 3.1.2 under openSUSE 11.1 x86. USB-support works fine (usb storage, mobile phone, webcam), except my smartcard reader. It's an O2micro Oz776:

VirtualBox returns "Failed to create a proxy device for the USB device. (Error: VERR_NOT_SUPPORTED)"

I'll append the related log file.

I don't know if this device should work under VirtualBox, so this could be a bug or a feature request.
