Thank you very much for the immediate answer.
I applied the patch - well, I had to do this manually, for some reason, I
assume bad formatting in my mail program, patch -p0 < patch1 didn't work. Or
am I using the wrong command?
Anyway, I changed the lines manually, and now I can compile and load the
module.
If I load the module, dmesg gives:
usbcore: registered new driver <NULL>
Then plugging in the adaptor:
usb 2-10: new high speed USB device using ehci_hcd and address 5
usb 2-10: configuration #1 chosen from 1 choice
But no eth1 shows up, and module loading and plugging the device seem to be
independent. I manually loaded usbnet but it didn't help.
Sorry, I really have no experience with kernel or usb development. ;)
