Fried Logitech Trackman Wheel Optical
Recently snagged a Logitech from a thrift shop for $5. After cleaning a decent hairball of dog fur out of it, it worked well for about three weeks, then began to have issues. The mouse would disconnect randomly and only work if I held the wire at a certain angle. I opened it to check if the cable was the issue, and sure enough, the end was frayed under the heat shrink, which I had missed when first cleaning it. I had a second mouse (by a brand called "Genius") which had a broken scroll wheel, so I decided to see if the cables might be interchangeable. The connectors were the same, so I crossed my fingers and swapped them over. my computer made the USB connect sound, but then said it was unable to recognize the device. When I switched back to the original cable, the same happened. Is the mouse salvageable? I can solder decently, so if the only problem is a fried SMD component I should be able to fix it, but I didn't see any visible signs of failure on the PCB. Thanks in advance.
