You can use dev_rdesc here instead.
Hi Henrik. Thanks for the tip. I tried comparing rdesc to hid->dev_rdesc
without any report_fixup call, but the problem (device nonfunctional
with "reset_resume error 1" message) still occurred. Upon looking at
hid_open_report, I noticed that it calls report_fixup on dev_rdesc
(pointer copied to "start") before it is kmemdup'd to rdesc. For most
HID drivers, the report_fixup method directly modifies and returns the
passed structure instead of returning a new pointer, so dev_rdesc is
also modified. Assuming that dev_rdesc is supposed to be the unmodified
data, I moved the report_fixup call in hid_open_report to after the
kmemdup. This combination successfully solves the original problem. I'll
submit a new patch version presently that addresses both points.

Hi Sergei. Thanks for catching that. The munging problem was supposedly
fixed in Thunderbird years ago! I guess I'll just mail the new version
from the command line.
