How to install USB keybaord and mouse on Dell 9150

Medium Priority
Last Modified: 2013-12-01
PC only has USB - no ps\2 ports. Seems that USB drivers are shot. USB devices work until windows loads then goes off.

How on earth can I get this working?

I have already doen a restore from the recovery console, thinking the drivers would be working again, but no joy. Was wondering if maybe all USB stuff was disabled in device manager but I know no way of getting into it without being able to click and type.

Safe mode and last known good config also give same results.

try to modify the BIOS, It's possible that the BIOS hasn't activate the mouse or keyboard support

Enable legacy usb support in the BIOS as daniel states

Where in the BIOS of this Dell 9150 can I find that setting - can't see it

Try the two top USB ports in the back of the PC.  I believe those are the ones that work during POST and up to the Windows boot.  If the system is still under warranty, online Dell chat should be able to confirm that.


Maybe I havent made it clear whats happening:

USB works fine before windows starts to load. As soon as windows starts to load then the usb devices go off. Dell will just say re-install Windows if I contact their support, I would think. I would be surprised if there was anything wrong with the machine per se, just something wrong windows, eg driver corruption or incorrect reg entry. I would that by re-installing USB totally (if poss at all) would correct either of my two theories.

What I need is a way to re-install usb in windows totally, but by doing it from reocvery console or some other bootable option.


Actually, as the restore didnt help I reckon the registry probably isnt the culprit, must be corrupt driver, unless anyones got any ideas?
I've had this problem before with Dell pc's - no PS2 and USB not working!!!
The last time I found that it made a difference which make/model of mouse or keyboard you tried to use.  Don't ask me why this happens, but first I tried a USB mouse and a PS2 mouse with an adapter: nothing; I tried a second USB mouse and found that the cursor would move, but only horizontally in a straight line!!! Finally, I tried another USB mouse and that worked OK.
I believe this model of Dell was shipped with a proprietory wireless mouse and keyboard - have you tried those?

Not the solution you were looking for? Getting a personalized solution is easy.

Ive only got a couple of different usb mice and keyboards - didn't make any difference.

Tried an adapter that lets you plug a ps/2 into a usb port and they (mouse and keyboard) had power to them after booting into normal mode but no response from any keys or mouse. I'm gonna try using UBCD4Win once I have created it - doing it now.

Any other ideas are more than welcome though.
