Apart from the issues that Phil mentioned, there are some technical considerations. You can get better response latencies with a kernel driver. Userspace drivers may be easier to debug and maintain, and in addition, I believe they are not considered to be "derived works" and so do not need to be released under the GPL. If you do decide to write a userspace driver, note that several bug fixes to gadgetfs were posted in the last few days. You may want to wait until they have been merged, or apply them yourself.
