Griffin Powermate (The really old version) acts very weird despite the axis being detected.

[relink2013]

I have one of the old USB Griffin Powermate knobs, I got it probably sometime around 2005 or so. The drivers were long since discontinued, and by default when connected to my Mac the device does absolutely nothing. On MacOS I am able to use a program called USB Overdrive to get it working and I can program it to do pretty much whatever I want. I've been using it to scrub the timeline when editing video, it's fantastic!

Im trying HID Remapper on a RP2040-Zero and when I go to try and get the functions through the monitor page this is what I get, which makes sense, at least in my uneducated view:

0x00010033         L2 axis         1   -7    7
0x00090001      Left button        0    0    1

The problem is that I cant map the L2 axis properly. Just as a test I mapped it to V Scroll and when I turn the knob to the right it shoots all the way to the bottom of the page very quickly and gets stuck there. I cant scroll back up, not even with my regular mouse. I have to disconnect the knob to use my regular scroll wheel. And scrolling up doesn't work at all.

Here is some relevant device info I got from USB Overdrive, I'm sure it's probably helpful in some way:

Im sure whatever the issue is, it's probably trivial but I don't know the more advanced capabilities of HID Remapper. The only thing I've used it for so far was to make a macro pad out of a USB Numpad, but that was easy.

I have a theory on what might be happening here. It's more of a guess, but we can test it.

Try defining a custom usage like this (in the Settings tab): Save, disconnect and reconnect HID Remapper and see if it makes any difference.

Alright! It definitely works! The scrolling is incredibly slow, but it's very smooth and consistent.

Glad to hear. You can try to use the scaling parameter on a mapping to make it faster.

Everything is working perfectly. Thank you, I can finally just plug it in and use it without having to jump through hoops to set it up every time.

I've hung onto this thing for years it's such a simple device but so incredibly useful. Plus it's really well built. I cant believe they stopped making them.
