Hi, I have a problem with my clicker 2 for STM32, when I try to connect clicker to USB HID Bootloader I have a message Unable to find device: USB HID Bootloader.

Hello,

There is a possibility that the bootloader routine got overwritten accidentally, so you would have to program another one by using a programmer. Sometimes it happens, since bootloader code is kept in the flash memory, along with your code and if the code accidentally writes something in that area or the content gets damaged by other means, bootloader stops working. Second reason could be a hardware fault. Try the bootloader on another PC too, if possible.

Best regards
