There are exposed connections for an usb port, the SoC has two ports one is 3.0 second is 2.0. I found out from reading the datasheet, and checked the connections with a microprobe on pads AG17 and AF17, they are indeed connected. I hookup a flash drive and powered it up via a step-down converter from 12v input to 5v, and maintaining the same gnd path, but when i try an lsusb in console i get "unable to initialize libusb: -99", I think there is something missing from the image (currently i'm on openwrt 22.03.3). Has anyone got this to work? I am not so much skilled in software as in hardware. mr33_usb

It's inspiring that you successfully traced those pins. You can find the errors meaning and diagnostics here.

You may want to check the device tree / pinmux is set up for USB on those pins.

Thank you for the info, I will look into it and come back if I get this to work.

Is the controller enabled in the host mode in the device tree? I don't recall that for stinkbug, bud indeed, this is the USB 2.0 port of the device, also (in theory) used for recovery.
