Hello guys,
I am far from the kernel development, but how can I test this?
For now I am using this package: https://aur.archlinux.org/packages/rt3593/
with lots of patches found in the internet.
This driver works well except one bug, which is explained here:
https://bugzilla.gnome.org/show_bug.cgi?id=700695
Best,
Alex

Did you use a tool for that or did you do it manually?

I recently tried to get my AVM Fritz Stick N v2 working under Kubuntu

heard it was supported in this driver.
Here some diagnostic logs:

Helmut,
Thank you for your reply.
I tried the patch, but it does not help with the CPU usage. I've also
confirmed that the original rt2x00queue_insert_l2pad never needs to call
the memmove() for the payload_length with the data I am transmitting, so
that probably explains why this patch doesn't help in this case.
Do you know of any other patches or fixes that might help with CPU usage?
John
(Sorry for the type-o in the subject line!)
