Stuck in FDU mode

[RussNelson]

Oops. I tried to reprogram my Solo Tap A, which seems to have burned the fuse that prevents re-programming. That's fine, but .... it was stuck in DFU mode, which presents with a different USB product id, so solo can't find it. However, reading the code, you can in fact find it, but you have to be root. Only .... if you've used pip as you to install solo-python, then it's not accessible to root. You have to uninstall it, and re-install it as root. THEN you can run it as root.
