This just started. A USB cord that I got with my Garmin GPS has become my primary cord for all my peripherals and has worked swimingly with my Crackberry since I got the comp two weeks ago. About ten minutes ago I put it in and got a "USB Device Not Recognized BY Windows" and my Crackberry wouldn't show up in the Device Manager. I pulled the unit out (that's what she said [sorry, been studying all day]) rebooted both the phone and comp, moved to another port and tried again. First the cord by itself and got the hooked up sound followed by an unhooked sound and a balloon from the system tray saying "USB Device Not Recognised..." and then got no response when I attached the Crackberry.
Oh, for a bit, without anything being attached I got the same message and the sound you get when something is hooked then unhooked. This happened a few times.
So, right as I started typing, actually after "This just started." I went and got another USB cord and it started working fine.
I continued with this post thinking this could grow into a bigger prob down the road. I never have continued luck with synching phones.
Is there a driver cd that came with the phone or one to download. I would start there first. Sometimes the vista geniric drivers get corrupted for no apperent reason. Go to device manager and check to see if there are any issues there with your usb devices. If there are click on the icon at top of page to uninstall and then reboot. This will reload the correct driver for that usb issue. Good luck.
