The problem of usb-skeleton.c compilation in Linux System ~ Could you please advise. Urgent.

The problem of usb-skeleton.c compilation in Linux System ~ Could you please advise. Urgent. -- Linux general technology-Linux programming and kernel information. The following is a detailed description. I recently learned how to write a program for usb communication between two linux-based servers!
The instructor only needs to complete the analysis of the USB driver in linux, and then add a function to receive and feedback information ..
Mainly for the application of usb-skeleton.c .. But according to the Internet (http://hi.baidu.com/wenlongren/ B... a993d7f6039e35.html) Guidance, according to the requirements after done, make found a lot of problems, can not pass .. I don't know what's going on. Which expert will give you some advice .. You can also advise if you have other methods to implement usb interface communication between linux servers .. Urgent ..


However, there are many problems after compilation .. Please advise.
