hi apk:
there are two usb ports on the port replicator, one on the side of the inspiron 3500. Under device manager, the usb reads:
intel 82371AB/EB PCI to USB Universal Host Controller
... and below is USB Root Hub with a error (exclamation icon) attached. Deleting/Reinstalling software, drivers etc has not corrected this.
I have checked the BIOS and there seems to be no mention of the USB anywhere - and no option to enable/disable.
HP said, on the phone, that it should be there - also, though Dell said that it (the USB option) would appear only when a plug and play USB hardware item was attached to the laptop. Hence the feeling of being in the middle. I have no other USB hardware units working - nor have had since I bought the laptop - it is only now that I want to use it.
Additionally, I bought a $16 usb mouse to see if that would kick start the USB softward - but to no avail.
Again, thanks and any way forward really really appreciated.
Regards/Ray
