Yes you're right.  I just didn't realize that you were going to use
both at the same time (the part related to the interrupt endpoint is
still commented out so I used to skip it while browsing through
speedtch.c :).  In this case directly manipulating the timer is probably
more convinient.  You may still want to reuse the timer persent in
struct work_struct, though.

Cheers,
