Guess I was thinking too much like "If it can be > done, why not do it." I've done stuff in userspace, and I've done stuff in kernel space. If I never saw another kernel space driver, I'd be happy.
Advantages to libusb: * Highly portable (including outside Linux) * Easy to debug (machine doesn't crash everytime you make a mistake, faster development) * Easy to code (don't have to worry about SMP locking, far fewer races, don't have to worry as much about memory allocation issues, and so on) Advantages to kernel space: * More ego boosting :-) * Allows you to provide standard interfaces (not applicable in this case though).
