Because stupid typedefs like that are evil, and not proper kernel coding
style :)

I upgraded to 2.4.20... no change.
And the uhci driver even locks up the system sometimes when usb-uhci
doesn't ;-)
But I found a trick.
I now unlink the send URB in the recieve_complete function.
This way it does get done.
And by just unlinking the 1 the whole send reviece process seems to stop
Sounds like a bug in whatever host controller driver you're using.
Unlinking an interrupt urb in its completion function is supposed
to work just fine. Does it still happen on 2.4.20? If this is
with UHCI hardware, did you try the other driver?
I have kernel 2.4.19 still... Should I upgrade?
Sorry me again.
Ok I'll shutup after this.
Just wanna let you know that my previous e-mail is wrong.
unlinking the send doesn't help!
It all continues in a happy send recieve loop!

Hello again
Ok I've done abit of research/testing
If I only unlink the URB used for sending data.. Then sending stops. And
recieve also.. sicne the device first wants to send data before
it can recieve data.
But when I also unlink the URB used for recieving data.. Then all of a
sudden everythin
