Default HELP: "USB Device Not Recognized"

Please Login to Remove!

My laptop does not recognize my Blackberry. I have a driver and reload it but it doesn't seem to work. Sometimes out of nowhere it connects to my desktop manager.

Any suggestions?

Thanks

Try using a different USB Port. I don't suppose you're using a USB Hub, are you. I have heard of some laptops not working all the time and swapping ports might work. Hubs have also caused problems.

Hope this helps.

Thanks. I have tried all 4 ports and it is the same on each.

It does appear as though all I had to do was ask the question here for the problem to go away. It is working now. I don't know how long it will last.

It's magic. All electronics are majic, you have to hold your tongue just right when casting your spell to the laptop mentally.

Sorry to say, but this is one of the hardest problems to fix. Here's some things to try.

You shouldn't need any special drivers, but make sure if there's anything special the machine's manufacturer requires for the USB ports, you have the LATEST version of their drivers handy. If you do need special drivers, and the ones you don't have are older, update them. Don't forget this may also mean Power Management software.

Speaking of which, make sure that if there's any power management of the USB ports, disable it (very rare though).

Try using MSCONFIG to disable as much as possible from startup including any services that don't look like their part of the OS. If that fixes the problem, add a few things back at a time until the USB stops working, and then figure out which one is the culprit.

If you have any software that addresses the USB ports - especially some kind of camera or disk drive software.

Go into Device Manager. From Device Manager's menu, select View --> Show Hidden Devices, and uninstall everything under Universal Serial Bus Controllers, then reboot. This will get rid of any 'phantom' USB devices. Reboot, and all the real USB devices should come back.

That's all I have! Good luck.

Keep us posted - this is not an uncommon problem.

I see this happen after attaching a third or fourth BlackBerry to a computer (not all at the same time, of course. I've done lots of handheld software upgrades). Rebooting the computer always fixes the problem.

Tried both of these with no success. It still does not recognize the device. Could it be a thing with my Blackberry and not my lap top?

Anyway, thanks for trying

Did you try and detect your BlackBerry?
Within Desktop Manager, go to Options / Connection Settings.
