OK 4 means it's been "triggered" (unlocked? opened?) from the default 6, so *something* is happening. Let me ask if you've verified these:

- you're running the 2.6.23.X kernel (2.6.23.8-63.fc8 e.g.)
- you do not have any barry or bcharge bits installed
- you are plugging directly into your PC and not an external USB hub

The first item has to do with having a new enough berry_charge.ko kernel module, earlier versions did *not* support the 81/83/88xx devices yet. The second is because the bcharge from barry conflicts with the kernel module berry_charge. The last is because there's some sort of bug (there's a ticket in Bugzilla) with using an external USB hub that hasn't been fixed yet.
