I have a Dell Inspiron 530s which will not recognise the presence of any keyboard at startup.
I have tried a number of different keyboards including usp wired, wireless and Bluetooth (Dell branded) and the behaviour is the same in every case.
First the wired and wireless keyboard (not Bluetooth) will work during start up to access the bios.
When Vista is finished booting the system will recognise special keys on the keyboard such as quick launch buttons etc, but does not recognise any propper keyboard input until the USB plug is removed and reinserted or the bluetooth devise is switched off and back on again.
There can’t be any problem with the USB, wirless or bluetooth interfaces not being active because the quick launch buttons work. I also dont think there is problem with the actual drivers because it will work if the keyboard is “turned on” after startup. There must be a problem specifically with the way windows is detecting the presence of keyboard devices at startup.
I have tried removing and reinstalling all of the USB hub devices and keyboard drivers but with no success.
Any ideas please?
Thanks
