[linux-usb-devel] Bulk urbs

[Heinrich du Toit]

Hi there

I now found out that in order to get high speeds with bulk transfer you need to submit lots of data at a time and you also need to submit lots of urbs at the same time.

So I'm thinking use the next field and make a circle que with some urbs.
Ok so each time the complete method is called that urb is actually again last in queue to be submitted. So I just load in the new data.
I hope I got this right about every next pointer pointing to the next urb and the last one pointing to the first urb? And then it keeps on getting sceduled.

Ok. What happens when I make actual length = 0? Can I do this. For example when there is no data.

And then how do I stop this circle queue of urbs?


Is this the fastest way todo this?
Or should I use a different approach?


Once again thanks for your help!
-Heinrich
