Stuck with no trackpad/keyboard on Monterrey install - USB 2.0 hub not working

Slightly ambitiously trying to get something modern running on my 2009 MBP. Tried Sonoma.

Ran into the USB 1.1 bug (meaning no trackpad/keyboard) described here. This means I can't install the post-install patches.

I picked up a USB 2.0 hub, as suggested, but running a mouse/keyboard through that had no effect. I confirmed on another machine that the device was working correctly as a 2.0 hub, but the MBP is unresponsive.

Having already converted the drive to AFPS, I don't seem to be able to roll back earlier than Monterrey - I've tried installing to that, but hitting the same issue.

Please help!
