Hi All,

I am having a USB CDC ethernet device whose driver exists only for Linux. However, my end application needs to run on Windows. So, I have set up Ubuntu 11.10 on Virtual Box running on Windows-7. Ubuntu is able to register the device but not able to open an interface for it, say eth1, etc.

[  382.531901] usb 2-1: new full speed USB device number 4 using uhci_hcd [  392.992690] cdc_ether: probe of 2-1:2.0 failed with error -32

My device is "Bus 002 Device 004". How to enable USB CDC ethernet on this device and expose this interface to Windows using a loop-back adapter. Any solution on VMware would also be helpful.

Any inputs about what might be the problem. I am able to register the device perfectly on standalone Linux machine but on Linux running on Virtual box, USB CDC ethernet device is not able to register. Any help would be greatly appreciated. -- Manavendra Nath Manav
