Hi,
I wonder if you could shed any light on an issue I'm having trying to
connect an RNDIS-based device to my Linux (2.6.38) machine.
The device is a digital PMR handheld radio, for which I am trying to
develop a control application. The manufacturer, Hytera of China have
supplied Windows drivers, told me it's RNDIS based and "feel free to
make it work on Linux" but will provide no further information.
Under Windows, the device presents itself as an ethernet controller.
When connected to a Linux machine, the kernel automatically loads
usbnet, cdc_ether and rndis_host but no ethernet devices are created, so
it looks like the kernel has *almost* configured the device correctly.
I've attached the relevant output of 'lsusb -v' and 'dmesg'.
If you have any suggestion as to what I might try next, I'd be very
grateful.
Many thanks,
Charlie
