Griffin PowerMate

Leopard has rendered my Griffin PowerMate (latest software version 2.1) as dead as the Monty Python parrot. Rebooting to a my cloned Tiger backup brings it back to life. Griffin has not replied. Any other Leopard experiences with this device?

Dual 1.8 G5, Mac OS X (10.5)

Hold the press! Look what I just found, right from the Apple Web site:
http://www.apple.com/downloads/macosx/drivers/powermate.html.
This is PowerMate 2.1 (the Griffin support page only has version 2.0),
and it works like a charm in Leopard. Woo hoo! Mac|Life without a
PowerMate (especially to control volume levels) is like having a USB
mouse w/o USB Overdrive. I like to have as much control as possible.

I got mine working again. Part of the problem seems to be a permissions issue. After doing some research it seems that the repair permissions function of Disk Utility in Leopard is buggy. When you run it after doing a Software Update upgrade to 10.5.1 you'll get SUID errors that can't be fixed. To fix this you need to download the full (often called the "combo" updater) 10.5.1 installer (110MB) from Apple's Download site.

Here's what I did:

Uninstalled PowerMate using the instructions on Griffin's website:


"Unplug the PowerMate
Open System Preferences
Right-click (or Control-click) on the PowerMate icon in System Preferences and select "remove"
Important! Delete the preference file from:Users/library/preferences (com.griffintechnology.powermate.plist)"


Ran repair permissions. It gives SUID errors that can't be cleared.
Ran the 10.5.1 Combo installer downloaded from Apple's site.
Rebooted.
Ran repair permissions again (this time reported no errors).
Ran the PowerMate 2.1 installer.
Plugged in PowerMate.

Everything is working now.

I finally found the culprit. In my case it was a software conflict. The PowerMate software did not agree with the latest USB Overdrive 10.4.8 under Leopard. But they coexisted happily under Tiger. Check your main PreferencePanes folder (remove the USB Overdrive PrefPane) and Login items (remove USBOverdriveHelper.app). Restart and see if that does the trick.
