Usb to Ethernet driver compilation on linux kernel 3.0 and above

Question

I cross compiled USB to Ethernet driver in the Linux Kernel source tree at drivers/net/usb/smsc75xx.c for Android Kernel 3.0.8. Cross compilation worked fine as well as inserting the Kernel module using insmod . But the ethernet interface does not show up nor dmesg detects module's insertion (using insmod ) or removal (using rmmod ). Since dmesg is silent about its insertion or removal, something seems not right?

How to debug this non-working driver in a non-verbose environment?

Answer 1

Check the drivers/net/usb/smsc75xx.c. It seems the driver is already in the upstream.
