I am a new person particularly for developing drivers in linux-usb. Previously I have done the same for windows.
I wanted to write now a driver for my custom usb design. For that can I use this skeleton code what are the changes I have to in this so that I can know first loading the exe to kernel. How can I link this inserted module into the kernel to my board connected.
Pl give reply positively.
When I compiled directly the usb-skeleton code obtained I got the fallowing errors () the file is from linux kernel 2.4.18-14 redhat 8.0)
