HP 8440 Laptop, USB problems
My laptop seems to have problems with most USB devices. It is running Win 7 professional 64 bit.
Firstly it will only take a HP external keyboard. I have tried a Microsoft KB and a Kensington KB and neither would work. A standard mouse will work OK.
Then I tried to use a Plantronic BUA200 BT dongle. Had one working after about 2 days of fiddling, then got a new one and it sits with a yellow triangle saying it needs a driver, but can't find any. The odd thing is the dongle will still pair with the headset.
So I bought a USB headset today and gets the same thing. Windows tries to install it, but says it fails to find the drivers.
Have run Windows update twice recently, so that is all up to date. USB flash drives seem to be OK.
Could this be a hardware problem ? Although it does seem to recognize devices, just can't find drivers.
