Samsung Mesmerize (i500 Android) - Device has Malfunctioned when Connecting via USB

I want to upgrade my phone to the latest version (EH09)
http://www.uscellular.com/android/software.html

As the title states, each time I connect this particular i500 to a computer, I recieve a little popup message that says the device has malfunctioned and Windows wasnt able to recognize it. Here is what I have tried already:

Powered off the phone

Removed the battery from the phone when the phone was off

Tried the same phone on another computer (windows xp and windows 7) - same result
Tried a different i500 on each of the above computers (this one connects no problem) -> this leads me to believe the problem exists with the phone, but I kept troubleshooting
Downloaded the latest drivers from http://www.samsung.com/us/support/downloads/SCH-I500

Investigated USB port (nothing looks physically out of place...nothing jammed in there or pins bent)
Enabled/Disabled USB Debugging Mode

Factory Reset problematic phone


...still the problem exists...

Note: The phone charges perfectly fine as an unrecognized device when connected to a PC and when connected to the wall.

Does anyone have any ideas out there?  Thanks!!

IT_Crowd,

I agree, this is a problem unique to your one device. I would guess it's either corrupted firmware or, more likely, a hardware problem - anything from a miniscule crack on a circuit board to a bad connector in the mini-usb port.

If it's still under warranty, get it replaced. Otherwise, so long as it functions ok, do you really need the upgrade?

Cheers,
LHerrou

No - I suppose I really don't need the upgrade. At this point, curiosity is the main driving force. I am going to take it to our local US Cellular to see what they say. I'll post back here when I know for sure whats going on.

Turns out the USB connectors were a little corroded. The tech at US Cellular applied a solvent on a swap to the USB connectors and it connected right up!

I'm not sure what the solvent was, but if you have this problem, it might be a decent idea to take the phone in after trying the above troubleshooting.

Great, I'm glad it was that easy!

(tucks that idea away for future troubleshooting)
