Hi Bjørn,
Those fixes seem to work. I could't reproduce the bug. Autosuspend
uses D3cold now instead of D2.
Thank for your help everyone.

Hi Bjørn,
If I find the time, I'll try the fixes this evening.
Thanks for the hint.

Hi Florian,
This is just a suggestion, but.. maybe you have a hub between a host
and a device?
In such case you need to enable remote wakeups for it. For example,
using your little script:
for i in `find /sys/bus/usb/devices/*/power/wakeup`; do echo enabled > $i; done;

Hi,
To enable usb autosuspend i use the following in a script after booting:
for i in `find /sys/bus/usb/devices/*/power/control`; do echo auto > $i; done;
for i in `find /sys/bus/usb/devices/*/power/autosuspend`; do echo 2 > $i; done;
After this new usb devices aren't recognized anymore. Whether
