I can't get my usb devices to work on my dell 4600 series pc. It won't reconise anything I try to plug in to the usb ports.

Try deleting your usb drivers.

Right-click My Computer
Device Manager
USB Controllers
Delete (Generic USB Hub)
Restart computer
(Windows will auto-install the drivers, on reboot)

Plug your device back in, and see i've it works.

My usb ports stopped working . i can;t download music to my ipod. i've tried all 6 of the usb ports with same resukts

Have you tried a different cable? If the cable is custom, sorry you will need to buy a new one to try it.
Plug in another USB device. Is this OK?
Do you use a USB Mouse? Try all the ports.
iPod cables are easily damaged. Ipod docks can be broken by force, twisting or dropping. Insert the iPod into the dock at the correct angle, gently.
Take care to insert the iPod cable straight, right side up. Do not drop the iPod with the cable inserted.
A foreign object like lint, dirt, paper or hair may be stuck in the connector. NEVER clean the connector with a metal object. Use a toothpick, carefully.

USB help


This sometimes happen when static hits your system. Try this next time, hold the ipod/camera usb cord in one hand and the touch your pc with the other. (This will ground you to the pc) Then plug in your equipment. Good luck

My front usb ports on my computer suddenly stopped working. I do have vista, and I swear the problem arose after an update. I can plug my ipod into them, and it charges my ipod, but it does not open...

Go to Start-Programs-Accessories-System Tools-System Restore and back your computer's date to some time before you installed this update. You will then know if the update actually caused the problem.

No Hard Drive or USB Device in Disk Management

If you are running WIN98 the USB drivers must be added for they don't come with the operating system as in later windows. (from Win Me on up)
And too, some times if you connect your devices in the front they are 1.1 instead of 2.0.
try using the ports in the rear where (if) that is where they are working for the external drives and see if the pen drive is reconised
so it will install the drivers.
Hope this does it for you, good luck, please leave a rating, thank you kindly

I have a 1g Lexar usb key it doesn't work. My computer doesn't reconise it plus the light on the key doesn't flash anymore... pls help as i have my good photo's on it

It could be your USB port that's not working. Try inserting your flash drive into a different USB port. It is possible that the line connecting the USB port was accidentally removed or loosened inside your CPU. You can also try opening your CPU and fix the connections of the front panel wires to the motheboard.

Trouble with Kensington Pocket Mini Hub USB 2.0 and Apple iPod.

I believe the reason you have this problem is your trying to run too many USB items than your pc can handle at the same time. Since you only have 1 USB port on your pc it may not have enough power to run an iPod and your DSL at the same time.

Front usbs not working(suddenly)

1) One of your USB devices have faulted, or is causing a resource conflict (or similar)
-- Remove all USB devices, and reboot.
2) Your USB chip/ports have been damaged.
-- Find a spare HardDisk or bacjup your data and re-install Windows and see how that goes.
3) Your Power Supply Unit (PSU) isnt supplying enough power to your PC (usually caused by a Video card upgrade). Try a more powerful PSU ... 400watts should do the trick
4) Bad memory (RAM) can cause wierd problems. run memtest for an hour to make sure your memory is ok

It seems that many people are still getting the 'USB Device not Recognized' problem from time to time. Unfortunately there is no easy fix.
Firstly, it's recommended that you make sure every one of your motherboard drivers are completely up-to-date, but you probably already knew that.
In XP, after a USB port isn't used for a long while the USB driver built into the OS sets the OHCI controller to suspend. When you plug a device back in, it can sometimes fail to 'wake up' properly. This problem was supposedly fixed in SP1 but there is a related registry hack that may still be able to help.
Run regedt32.exe and navigate to;
Create the Usb key if it doesn't already exist. Under this key, create a new DWORD value called DisableSelectiveSuspend and give it a value of 1. Then restart the PC.
A long shot perhaps, but I recall having similar problems with a USB hub built into my Microsoft keyboard and adding this key seemed to solve it. It wouldn't hurt in trying .
Alternatively, removing all entries relating to USB in Device Manager and all associated USB drivers will force XP into refreshing the USB driver stack.
Begin by unplugging all USB devices, then use Add/Remove Programs in Control Panel to uninstall any USB driver software. Next, boot up into safe mode and go to Device Manager. Once in device manager make sure 'Show hidden devices' is checked under the View menu. Uninstall all device entries in this order;
1. USB peripheral devices (printers etc.)
2. HID and/or Composite USB (Human Interface Devices) You're using PS/2 input devices so you may not have this entry.
3. USB Root Hub(s)
4. USB Host Controller(s) (Universal or Enhanced Host Controllers)
Then boot back into Windows (not safe mode) and it should populate the Root Hubs & Host controllers again. Proceed to plug your USB devices back in, starting with your powered hub. Be aware that most USB printers and scanners need to have their drivers installed first before you plug them in.
Hopefully some of this may be of help, let us know how you get on.
