I have one of those protocol analyzers in between and it doesn't see
anything. I tried to look for where the EPROTO is being returned from
but grep -r doesn give me relevant results. I also looked at the
sanity checks in submit_urb but I don't think any are doing anything
about the speed. Would you know which file would contain the "lowest
level" routine that sends the packets?

Thanks.
