How to revive Prime from sudden death

[kk6pr]

I had the same problem updating on a Windows 10 64-bit machine. The calculator displayed some error, the computer said the USB driver failed and continually tried to install some update (I assume). Several small icons appeared for each attempt (3 or 4 simultaneously), but it obviously wasn't working.

Disconnected the Prime from the computer - did a pin hole reboot, it recoverd normally.

Rebooted the computer and tried the update again - it worked successfully this time.
