USB host mode

Hi to the flipper community!

I’d like to use my chord steno keyboard with flipper (implement key codes translation in the firmware and emulate normal keyboard via bluetooth), but when I connect the keyboard to the device, it doesn’t power up. The keyboard has leds which are normally led when it is attached to the computer, rpi or just usb type-c power supply, so, I assume the issue is in the usb being in the device mode (but I’m a usb noob, so, might be mistaken).

As I’m not very familiar with flipper hardware yet, my question is about overall chances to make things working.

At the moment I’m using https://github.com/Anodynous/stenogotchi, which runs on RPi with plover and bt keyboard emulation, but it requires external power supply.

Thanks for any suggestions and ideas!

Flipper doesn’t support being a USB host at the hardware level, and there are no workarounds sadly

Thanks a lot!
