Looses mouse and keybord function after approx 15min running
The machine looses mouse and key functions after 15min and does not recover from it, until it is shut down. Then it is fine again for another 15 minutes…I tried of course another wired keyboard and mouse and switched USB ports, but the problem persists. Any clue where to look for the disconnect.
Hi Dan, I have tried any one of the 4 ports with the same result, once the freeze occurs there is no movement. The voltage on those port is 5.09V 0.1 A after a freeze, using one of the USB voltmeters you suggested. Trying to do a time machine backup I notice that it is not only the mouse click action which fails once it freezes: The time machine backup process also stops, sitting now at 8.87GB without moving any further…I should mention also that the machine still registeres mouse movements, i.e: the curser can be moved anywhere, but it does not click or select anything anymore. I guess I will try the SSD from this iMac in another machine to see if it is a corrupt OS or if it is hardware in the machine. Also when I had tried to reset the USB hub in terminal unloading the kext, it was unable to do so. I used this command: sudo kextunload IOUSBMassStorageClass.kext .
