I also tried unplugging the computer and removing the laptop battery as well as draining the battery of the fuze. It didn’t solve the problem either.
Did you really think draining the Fuze’s battery would solve an issue that it obviously with your computer?
Have you checked to see that the USB setting has not been switched back to MTP or Auto-Defect somehow?
Is the laptop plugged into AC power when you are trying to connect your player? Many won’t put out enough juice to make a data connection while running under their own power on any of their ports. At least you still have others that will work.
This is obviously an issue within your computer, isolated to 1 USB port. You said you un-installed & re-installed the drivers for this port. Did you install the correct drivers? Does your Fuze charge & connect in this port and can you transfer files? Or is it dead in the water on this port? If everything else seems/works normally and it’s just the matter of it identifying as an ‘Unknown Device’, maybe it’s just a simple matter of re-labeling the device.
If nothing works on it though, then you’ve still get some ‘Sherlock Holmesing’ to do.
Thanks Tapeworm, You’ve got a very point here that the issue seems to be on that particular computer port. But I couldn’t eliminate the possibility that it is a combined problem of the computer and the fuze. Actually, you know what people do in frustration. :wink:
As for the other points: I made sure that it is in MSC mode all the time.
The laptop is plugged into AC.
For the drivers, I should have said I uninstalled all the USB device drivers under Control Panel/Device Manager in safe mode, and rebooted to regular mode, and Windows Vista reinstalled the drivers. Because I didn’t have any external USB devices connected, there was no drivers installed for “unknown device.” But as soon as I plug in the fuze in the faulty USB port, a driver is installed for the “unknown device” detected.
The fuze is charged ok in that port, but no file transfer can be done.
Here’s what happens when I plug the fuze in the faulty port. The fuze first shows “Connected”, then “Writing”, then “Connected”, and it starts charging. The computer shows an error message of “unrecognized device found” and you cannot see any drives (for the internal memory and external microSDHC card) as you would if it is plugged in a working port.
You’re right that I still have some working ports to work with, but I really want to know if anything was really messed up on my computer (any hardware damage?) and, if possible, I would like to know what had happened so that I don’t do it again to mess the other ports up.
