can attach any external devices

[99sei]

For some reason i cant attach any external devices through my usb ports. It wont recognise when my phone is connect, my mouse, ipod ect ect. Any ideas whats going on? it has only suddenly happened. I have reset the computer to a previously stored time when i know it did work, still them same though

I think you will find that if you delete the usb controller in device manager and reboot then windows will reload it (this has worked with XP in the past, I am not sure on vista though)

where is this usb controller? i tried looking for it last night

 

[custard]

you need to go into device manager
eg control panel>system maintenence> device manager(if you dont see it change to classic view)

 

[99sei]

wont allow me to delete it, any more ideas?

 

[99sei]

Ive got the option of roll back, would that be any better than deleting all the drivers?

 

[mattsmart]

try rebooting into safe mode (before you get to the scrolling green bar when vista starts, hold down F8 and select safe mode from the menu). Then try disabling/uninstalling the usb controller as above, then reboot. If that doesn't work try a rollback on the driver for the controller.
Do _all_ your USB ports not work? Could be disabled in the BIOS, or you might need to redownload your motherboard drivers.

havent got vista, dont like it, im an XP man. All my usb ports are down. When ive checked their status it has said they are all working fine and enabled. Not sure about this Bios this, whats that?

BIOS - Basic Input/Output System. [ame]http://en.wikipedia.org/wiki/BIOS[/ame]

Press F2/Delete/F12 during boot to enter the BIOS. Somewhere it will have the option to disable various controllers including USB.

If you haven't reset the BIOS I doubt it's been disabled. More likely the driver needs updating. You should be able to uninstall the USB device in device manager then re-scan the computer for changes - OR - right click them and choose update driver from microsoft - OR - install the latest motherboard chipset drivers

 

[99sei]

Drivers unstalled and computer reloaded them - still no play with the USB ports. Couldnt find the thing in BIOS.
Any more ideas?

Are we talking front USB ports, or ones on the back?

Has it previously worked in those ports?

 

[99sei]

Front and back, both working fine till mon i think it was. Never had a problem with them before that either.

do any of your usb devices have an LED on or anything so you can check that they are being powered when connected?

To delete the USB controllers you need to expand the section that says USB controllers and delete the bits below. If not try deleting the root hub parts. Apologies - see you tried it.

 

[Ucof]

Have you got all the latest Windows updates installed?

 

[99sei]

ive got the latest ones for the hub drivers, it wont allow me to udpdate them as they are all up to date.

They have power as the light comes on on my mouse when it is plugged in. Its really starting to annoy me now as its preventing me doing my planning. Any more ideas?

 

[Ucof]

Ok, so the mouse light comes on, but it doesn't recognise the actual device?

What motherboard have you got? I need model, not just make

 

[99sei]

How do i find that out?

 

[Ucof]

You can either take the side panel off and read the motherboard, it will have the make and model on it somewhere. You might need a torch.

or..
use this program:

Got my mums friend out to this problem as i dont do computer repairs. He builds computers and makes software for big companies and he was stumped. Motherboard was fine, everything enabled even tried to install a usb card but still wouldnt recognise a usb device.
I'm getting it back tomorrow so am going to save everything on it and reset it to factory and see what happens, after that im lost

..and your motherboard is...?
