Did you do it by calling the new usb_driver_set_configuration() routine in the patch I sent? Or did you do it by calling the old usb_set_configuration() routine? That is guaranteed to deadlock if you call it from within a probe method. > I can not thing of an other place in the module where the configuration > switchin would be in the right place. > > More and more I come to the conclusion that your first statement was the > best.

It has been done lots of times. In fact the kernel supports entire architectures which are used by only two or three people in the whole world!
