im using a wireless keyboard and mouse (MS 6000). when the wireless receiver was connected directly to the computer case everything worked fine (i had to enable some USB related setting in the bios to get it to work at first).
now i got a 4 port USB hub, when i connect the keyboard/mouse receiver through the hub, the computer gets stuck at the "detecting USB devices" (or something similar) stage during boot.
if i connect the receiver back to the computer case and switch it to the hub after windows starts, it also works.

any ideas how i can have the receiver connected through the hub permanently and have the computer boot ?

thank you.

When the BIOS has to setup a hardware device for being available during booting. It has to "driver" the hardware that is there, so it can function prior to the OS setting-up that same hardware.

If you look In device manager, at how the "connection" and driver setup is different when the Hub exists, you could see that. Basically the BIOS would have to setup the hub AND the hardware device. The Bios setting up a "hub" should not be much different than the hub(s) that are on the motherboard itself, but it is the motherboards own hub, it was designed/tested to work with it.

It sounds like the limitation might be based on the BIOS software being able to recognise and setup that hardware (prior to the os) , with That extra piece of hardware in existance. The extra connection.

Is it possible that you could use the Hub to extend your capability to run other hardware, and leave the items needed to be supported by the BIOS directally connected? The Keyboard and any USB Boot devices you might need, would be directally connected, Printers and nets and storage devices, gaming devices, cameras, scanners, on the hub.

The other possibility is that the HUB was on sale :-) for a reason. Is the hub also a powered hub?

i got the hub specifically for the wireless receiver, the computer case is a little too far from the desktop (actual real life desk top) and i get weak a signal that causes the keyboard/mouse stop responding on occasion. it is not powered. –  yurib Dec 30 '11 at 2:52
    
In that situation would Just a USB extention cable work? –  Psycogeek Dec 30 '11 at 2:53
    
that's was my next move, i was hoping the hub wouldn't go to waste though... –  yurib Dec 30 '11 at 2:55

It sounds like the BIOS thinks the hub is a bootable USB device. If you do not regularly boot from USB, you can disable this feature in your BIOS settings or bump USB to the bottom of the boot order list.

To access the BIOS settings, press the proper key as instructed by the BIOS interface at boot-up. It is usually a function (F1-F12) key or Delete
