hi all,
I've just gotten the new Black Griffin Powermate (http://griffintechnology.com/products/powermate/). It differs from the alum one in its hardware interface, specifically in that its payload is 6 bytes (as opposed to 3). basically what you get when you try the default kernel drivers is this dmesg output:
| Code: | powermate: Expected payload of 3 bytes, found 6 bytes!
input: Griffin PowerMate on <NULL>
drivers/usb/core/usb.c: registered new driver powermate
Debug: sleeping function called from invalid context at include/asm/semaphore.h:119
in_atomic():1, irqs_disabled():1

i found a patch for the first problem (the payload size) here:
http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.0-test10/2.6.0-test10-mm1/broken-out/powermate-payload-size-fix.patch
but i'm lost on the sleeping / IRQ issue.
has anyone else gotten this to work?
thanks,

|

I had to play around with it for a while, but I finally found a powermate patch that works with XMMS.
I'm running gentoo-dev-sources (2.6.7-gentoo-r11) and my kernel has been configured as follows:
| Code: |
Code maturity level options --->
[*] Prompt for development and/or incomplete code/drivers
[*] Select only drivers expected to compile cleanly
[*] Select only drivers that don't need compile-time external firmware
Input device support --->
--- Mouse interface
[*] Provide legacy /dev/psaux device
(1200) Horizontal screen resolution
(1024) Vertical screen resolution
< > Joystick interface
< > Touchscreen interface
<M> Event interface
USB support --->
<M> Support for Host-side USB
[*] USB verbose debug messages
<M> EHCI HCD (USB 2.0) support---
USB Human Interface Devices (HID)
<M> USB Human Interface Device (full HID) support
[*] HID input layer support
[ ] Force feedback support (EXPERIMENTAL)
[*] /dev/hiddev raw HID device support
<M> Griffin PowerMate and Contour Jog support |
Then I downloaded the where-powermate binary and the xmms-pandemic-powermate-module from http://syn-recon.net/code-projects/powermate/.
All the docs for installing the binary and module are in the tarball's readme.
The only caveat is that the where-powermate binary and xmms (with the pandemic general plugin enabled) need to be run as root to prevent segfaults.
Have fun! |

I found that http://powermated.sourceforge.net/ works well for my silver powermate, and they don't have a disclaimer such as:
| Quote: | The plugin causes XMMS to segfault on close, not sure why but it was present before my addition.
Since i just want it to *work* i could care less about the fix  |
