Thank you Claydots, was able to salvage my G10 due to your posts. As some others have reported, my USB input never from the get-go provided a solid connection with the micro USB cable as the micro USB would only plug in about half way. The inevitable happened with a total failure of the port. I had been very careful with the fragile power supply connection but it certainly was no surprise to me when it eventually failed. I can't do updates since the USB port is shot but at least the unit is functional and the connection is now so much more secure. Though I really like the unit from the functionality/use-ability standpoint, there is just no way I could ever recommend this product unless Line 6 changes this connection.
