Hello hackers!
I registered to ask these questions...
First of all I want to thank Hasu for his tremendous work of creating the tmk firmware and making it open source! This is an impressive accomplishment.
So I do have your usb to usb converter here and it works really well with a number of my keyboards. It doesn't work with two of my keyboards however, and I need a hint on how to debug this. So the symptoms are like this:
- keyboard is plugged in, and its leds flash, are off for a second and then num lock led lights up
- the keyboard does not emit any keycodes
- hid_listen shows this:
usb_state: 12
usb_state: 20
usb_state: 40
usb_state: 50
usb_state: 51
host.Task: 2709
usb_state: 90
Here are the usb descriptors of the keyboards that do not work.

Both keyboards should be HID BOOT compatible, I think.
So it would be cool if you could give me some hints on where and how to debug this. Thanks.
Best,
