not sure what an energy error is, but i know a bad usb port when i see one
(kind of like what potter stewart said about pornography)
you could see if inkjet performance has one (732 330 4275) inkjetperformance.com
they also offer board repair & we have made out pretty well with them (no one scores 100%)
it would obviously be either a bad usb connector or the usb chip needing to be changed. (easy for me to say)
it is probably a good time to remind you, if you had a humidifier and kept the humidity up, that port would probably still be good
(i lecture everyone at this time of year, when heating season is starting) much cheaper than killing circuit boards
