As you are writing to a tty device, you need to set up the tty layer properly from userspace before calling write(). See a Serial Programming HOWTO for information on how to do this. If you don't do this, the tty layer is in an unknown state, and odd things can happen on what kind of data gets transmitted (I've seen this firsthand.) But this shouldn't be causing an oops :) Can you load the driver with "debug=1" and send the kernel debug log output for when you run the program? And have you tried the uhci.o driver instead of the usb-uhci.o driver? thanks, greg k-h _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
