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 e518816@ubuntu:~$ lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 002: ID 0e0f:0002 VMware, Inc. Virtual USB Hub Bus 002 Device 004: ID 0e1e:0800 e518816@ubuntu:~$ 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. -- Manavendra Nath Manav _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
