You're making these devices worth your money ;p. I did a quick test on a Win machine and np!

The python world is unknown to me but I see it has potential! AFAIK smb wrote a neat frontend in py back in the days.

How did you find hid codes for DV special keys, while everything else follows Usage ID numbering? My suggestion is to add hid.man.txt file with above "Usage:.." description and list with "HID codes for standard and special keys".

Marking as resolved, well played.

I have small issue on my Win machine, when before it registered device as CDC after connection but after HID gadget activation it now only register it by HID device and I can't connect handheld to old serial port.

When the device is in HID mode serial connection won't work.

I checked, and after exiting from HID mode and switching back to CDC mode serial connection works correctly on my Win machine

Maybe add another function translate_special_keys which will translate E0-E7 values from the usage table to bitmask values.
It will be more user-friendly

Great much easier to understand now.

Serial connection works correctly on my Win machine

It did not on my, even after rebooting or changing to stock SD. It always register as HID device after using gadget, I had to unregister driver from Windows and then it showed CDC again. This was on old 8.1 machine, I'll try latest Win tonight.

this could be related that we always use the same product/vendor ID, and old Win cannot handle it

Yes it works correct on Win 11, so I guess it's the best to leave it as it was (e507b56 - this somewhat works but I've to restart handheld to enable ms-gadget again).

When u connect USB OTG changing mode to peripheral it seems it doesn't revert to b_idle after disconnecting devices, so the USB-HID start even when devices are not connected. On the second usb-hid.sh run every seems to go back to normal.

in fact, it should not require device connected, but when it is in b_idle state, it hangs, so this check is a workaround to avoid such issue
