Hi All,
I'm currently trying to use ndiswrapper on my Mandrake Cooker box but
currently loading driver failed when ndiswrapper used usb_get_descriptor
and get an EPROTO error
My kernel is a 2.6.12 one (not the vanilla but the mandrake one) on
which I enabled debugfs and usbmon to start some debugging. It seems in
fact that performing usb_get_descriptor by libusb is working.
Here's my USB controller description :
