Im having the same problem. My controller is in bootloader mode and i plug it in but the rapidfire software willnot detect. Ive tried all the same things you have and uninstalled and then reinstalled the rapid fire software. Anything would be helpful at this point
The Dropshot on my odins raven doesnt even work. Ive had my controller for probably 6 months and sent multiple emails about but havent been notified of why it wont work
