I have attached UBS Printer and Scanner devices to my computer, but always there is message that “USB Device not recognized” and this message appears again and again. What is the solution, please suggest. Thanks a lot.

@Amit It’s very likely your hard drive crashed.

oh, i forgot:

If problem still happens after you installed new drivers, try to disable one of the USB port in Universal Serial Bus Controller in Device Manager. That works for me.

Ok.

Same problem: “USB device not recognized”

Then i try to remove all of usb ports drivers, search and delete all USB driver files (like usbport.sys, usbhub.inf, usbehci.sys, etc. if any) in inf folder, dllcache folder, system32 folder. After that i try to re-install the drivers. And that solve my problem.

Note: look at “Disk Drives” section in Device Manager, if there’s a name of your usb, try to remove it too.

Ok.

@Kathi That’s possible, but it wouldn’t explain how USB devices work when plugged into the back and not when plugged into the front.

Regarding your hard drive, it’s hard to say, but narrowing it down to exactly what causes it is the first step to troubleshooting the issue.

Just a dumb thought - I am going through the same issues…but is it possible that there is just not enought power to run allll the things we have plugged in to USB ports? (like trying to plug too many things in if your electrical wiring is really old)
I have an older Dell - with 2 USB ports in back (one for printer, one for external hard drive) and I have a USB hub plugged in to the front). My external hard drive refuses to power up. I unplugged all USB devices, & one at a time tried adding. Sure enough, as soon as I added anything except the EHD, the EHD would slowly lose power. I went through the usual…thinking it was a power supply issue, purchasing a new external hard drive, and the exact same thing happened with a brand new one. Anyway…does this mean I have to plug & unplug everything each time? do I need a newer computer? Hmmm…would even that solve the issue?

My problem is a bit different:

I have a Sony Vaio running XP Pro. I was transferring a bunch of video files to my new SimpleTech external drive when another process started up and froze my machine. After waiting a long while for it to resolved on its own, I cold booted the machine. When it came back up, NONE of my 6 USB ports were working and I started getting the ‘USB device not recognized’ message. All ports and all devices were working before the reboot.

I’ve followed everyone’s advice: uninstalled all of the ports and restarted so that they would reinstall, deleted the vid entries from the registry, etc., nothing works. After deleting the vid entries and restarting, I got the messages that it had detected new hardware and new USB devices properly. But when I tried looking at them, they were Unknown devices.

So it seems like the ports are OK, and I know the devices are OK, they just don’t talk to each other.

Any other ideas?
