[Deleted user]

Hello

I have issue flashing firmware to CrazyRadio 2.0
After identifying device usb-flash.py script gives an error
Would appreciate any ideas or suggestions

Same here, tried on 2 different computers for hours (with tons of workaround). It seems the moment I tried sending 0x40 (for example dongle.ctrl_transfer(0x40, 0xFF, 0, 0, (), timeout=usb_timeout) ) it didn't work. Also I tried many other protocols, but it just doesn't seems to work.
If someone know what is the problem with Crazy Radio PA 2.0 and how to flash it, it can help
Thanks!

This issue also happens with the Logitech unifying dongle
