Solved USB devices connected to a USB hub at Windows login screen

Specs: XP SP3, 3Ghz, 4GB Ram
Is it possible to have a usb hub act like an extension to the computer USB port so that you can have devices such as a wireless mouse and wireless keyboard available to use at the login screen?

Is there something I need these hubs to have (internal parts to be recognized by Windows?) to be able to use USB devices at startup or is it not possible to extend the computers USB ports with a non powered hub to use USB devices such as a wireless keyboard to be ready for use at the windows password prompt?

Non powered USB hubs are ok for devices that need not powered from the USB port. Mouse and keyboard need power. The wireless receiver (wireless keyboard/mouse) also need power!

A USB hub won't make services available that aren't already supported by the port.

If you're having a problem using a USB connected keyboard until windows loads then go into bios setup--you'll probably need a wired PS/2 keyboard--and check the USB settings there. The option you're looking for is often called dos or legacy USB support. It may be called something else with your motherboard and you may need to consult its user guide.

Well I don't know about having to adjust any BIOS settings. These devices, the wireless mouse and keyboard, both work when plugged directly in to the computers USB ports but when using the USB hub they no longer work at boot up. This must be a trend with lower priced USB hubs? I have tried it with two different types of non-powered USB hubs, 2 different computers and question if it has something to do with the amount I have paid for them. Perhaps the computer does not support USB hubs until the OS has been fully loaded or these hubs are missing something required by the OS at startup to recognized the different devices from one computer port?

This is it.

Is it related to these two different computers I have tested this with or is it that all computers do not support USB hubs until the system has been fully loaded?
