Description of problem:
We tested a Griffin Powermate with the latest kernel of RHEL3, but it is not correctly recognized from the kernel: The error message was "Expected payload of 3 bytes, found 6 bytes!"

Steps to Reproduce:
1.Plugin powermate device
2. type 'dmesg'
3. Compile user tools from http://sowerbutts.com/powermate/powermate-1.0.tgz
4. call 'rotomatic'
Actual Results: No Powermate device was found
Expected Results: The testprogram should display the rotate steps.
I have rebuild a custom kernel and aplied the 2.4.21 patch from: http://sowerbutts.com/powermate/powermate-2.4.21.patch
With this modified module testprogram shows the expexted results.
But this is no sulution, because this would prevent our customers from updateing the kernel from future versions, as we can't expect them to recompile new kernels
and apply patches to c file.

This patch, if aplied to /usr/src/linux/driver/usb/powermate.c does fix the
This patch is in RHEL 4 already. Is a migration feasible?
Not at this time. The current Hardware at customers site (HP-xw4200/xw4300) is
still delivered with RHEL3, and the roadmap of our software does not include RHEL4
either for the next 6 month.
QE ack for 3.9.
RHEL3.9 is a bugfix only release but this is a Feature addition. It does not
seem to me that this driver should have recognize the hardware?
I understand that the customer has been waiting for this a long time but I do
not see how I could ACK it after RHEL3U8.
This is simply a bug fix from upstream 2.4.22 (from 3 years ago),
so I'm removing the FutureFeature keyword.
