At first, I thought I had an issue with my new camera, which suddenly started giving me the "Connection failed!" message when I tried to download pics from it, when I had already successfully downloaded 2 other sets of pics.
Now, I'm having a problem with my printer. "Printer Not Ready -- check all connections," blah, blah, blah. I even changed the ink cartridge, though I don't think it was completely out.
I have tried to use all 3 ports with both devices. I think it's odd that I would suddenly have a connectivity issue with both my camera and my printer, so I'm thinking it's the USB ports. Is there anything I can do?
None on your monitor anywhere? None on your Keyboard?
The 5v lines on the PSU power the USB connections, its possible that your PSU's 5v lines are deteriorating. Do you have another PSU available that you could try to use in your PC to see if anything changes?
