well from my experience it could be a number of things.
Bad USB device (Curcuit board)
Bad Usb Port
You have to eliminate each and every cause, theres is no real cure, in electronic without a curciut probe to make sure.
Voltage can go bad, Solders can break Capacitor can blow up, diodes can go bad sending the wrong voltage. Its would be very hard to pinpoint the problem.
Without more detail or error log i cannot tell you much, but i would try everything i can to eliminate all usual suspects like trying different usb devices if A DEVICE works and some doesnt well it could be the device as USB devices can go bad(interface) the curcuit board of the device could fail, they tend to get REALLY hot when used alot. i have some usb enclosure on my system and i have found that some usb device do fail from time to time, they just refused to be recognized by the computer i would remover the HD from it and replace the usb interface and it works.
so what im trying to say its "really DIFFICULT" to pinpoint the problem. without doing a trail and error run with the hardware you have, eliminate the small suspect first like trying the device on another computer, if you have the same product and it work in the same port and not work on another computer then you have a suspect, the device is failing.
process of elimination.
Good luck being an IT takes alot of patient. Alot of work.
as for future references theres not much you can do when a product "just fail" a number of thing could have happened. use the process and think about how it could have happened. power spike, wear and tear, abuse, any number of things.
i could write a book, but unfortunally i dont have the patient for it.
