I have a Adafruit RP2040 Feather with USB Host and it doesn’t see the input from my USB device. It will see one of my USB keyboards, but it won’t see my other keyboard and It also won’t see my other device, which Windows sees as a standard HID mouse, and a standard microphone and speaker is not seen by the HID Remapper, as the button on my device when I push it is not recognized. When the device is plugged into a standard USB port it sees the button as the middle mouse button, but this is not seen in the HID remapper.
You can try dumping the report descriptors and some traffic from the devices that don’t work as shown in this video and post the capture file here, but in the end some devices just won’t work. A few only work with the dual Pico setup, though that’s less common now.
Ohh here is some info on the device I am trying to connect Teardown of a General Dynamics Military Audio to USB interface box
I don’t see anything suspicious in the report descriptor so it’s probably some lower level incompatibility.
But just to be clear: you know that once you connect it through HID Remapper, the audio interface functionality won’t work at all, right? (And I doubt you want to use it as an expensive middle mouse button.)
I was hoping that the audio would be able to pass through. Do you have any recommendations for other projects to look at to solve my issue?
Software on the computer is probably your best hope. I doubt you’ll find a similar solution that passes the audio through but intercepts the mouse inputs.
