Pro Micro bootloader and driver problem..

Postby MichaelSmith » 18 May 2018, 12:36


I somehow managed to wipe my bootloader. I think I managed to program the bootloader again using the AVR Pocket Programmer and the DiskLoader-Leonardo.hex file in the Arduino/hardware/arduino/bootloader/diskloader folder, but since then I cannot connect it to my Windows 7x64 machine. In the Device manager I get "Unknown Device" under the USB controllers, Error Code is 43. I tried uninstalling, re-installing - nothing works. If I tryt to upgrade the driver, windows tells me that the driver software is up to date and shows it as "Unknown Device". I removed all oem.inf files in the Windows/inf folder which referred to Sparkfun micro pro or Leonardo.
Up until the bootloader incident, all was just dandy.
So, any ideas of what I messed up and how I could get it back working again? Does the Pro Micro need a special bootloader or can I use the one from the Arduino collection?

Any help will be apprecited.
I didn't find the right solution from the Internet.
