| Here's a new patch to try instead. It supersedes the earlier patch.
Great, it works, thanks a lot for very prompt reply! Tested on 2.6.31.3
and 2.6.32-rc3.
I have another (smaller) problem: the firmware download always fails on
first insert (or reboot), which results in no serial port created; it
succeeds on second insert (trace below). It has always been the case
since I bought this device (as recommended by Greg KH).
First insert:
