This patch contains an initial version of an USB network interface
(RNDIS / CDC Ethernet) emulator. It has been tested with Linux (Fedora
Core 6). It uses the same vendor and product ID's as the linux gadget
network device driver, therefore the "linux.inf" file from
Documentation/usb of a linux-2.6 kernel source archive can be used under
windows.
Usage:
-net user -net nic,model=usb -usbdevicenet:0
gives you the default setup (i.e. without any -net option), but with the
USB adapter instead of the default PCI adapter.
Problems:
I couldn't so far get it to work under Windows, neither on W2K SP1 nor
SP2. Although on SP2 it gets a lot farther. Both versions start
accessing the device, and then sometime an interrupt in terminates with
USBD_STATUS_INTERNAL_HC_ERROR and then the device more or less hangs. So
it looks to me like a USB host controller emulation bug or a bug in the
host controller driver... Maybe someone has an idea...
