Hi,
Your log looks like they work - nothing is being suspended anymore ;)
Do you have any idea what kernel driver (try lsusb -tv) or userspace
software is using this device? It's quite possible that the driver
simply requests a reset explicitly, either as a matter of routine or
to recover from some problems.
Regards,
Michal
