I can enter and navigate BIOS after bootup with the keyboard plugged
into a USB port, and once XP starts it doesn't work. However, the mouse
shows no lights or other sign of life at either stage.

I can find no reference to USB2 in Device Manager. There is a 'standard
enhanced USB to PCI host controller'. I would not assume the drivers
were properly installed. I paid a local computer ' expert' to install
my new motherboard, but the fact that he kept asking me where I thought
the various connections should go, did not fill me with confidence!

How can I ensure that USB2 and Enhanced USB are enabled, and the
drivers are installed?

Thanks

Gary
I would say your lack of confidence in your 'expert' is well founded.
The
word enhanced indicates USB2 of some sort, but the description is
puzzling, so I have some other questions. Besides the direct
motherboard
mounted USB sockets, do you have any mounted on a backplane slot
cover, any case front USB ports, or a separate USB PCI card?
The spec for the motherboard says '2 x USB 2.0 headers support
additional 4 USB Ports'. I have 4 ports on the front of the case and 4 at
the back. My only PCI card is for firewire,

Thanks

Gary

"Standard Enhanced" seen in Device Manager, is shorthand for USB2.0 .
It would typically be seen, coming from an Intel Southbridge with USB2.0
capability. In the example here, there is a PCI card with a NEC USB2 chip,
and also an Intel Southbridge with USB2 capabilities, so ports are coming
from two places, complicating the example.

Checking the specific "Enhanced" USB entries, and looking at the driver
list for the specific item, would show a Microsoft USB2 driver or drivers
installed.

A mouse shows lights, according to the light type. My current optical
mouse
uses a strong red LED source. The obvious red color is a giveaway. A
laser mouse may use an infrared laser, which is invisible if it is far
enough into the infrared part of the spectrum.

Use UVCView and see whether USB device enumerations are visible, to detect
a device when plugged in. This archived page has a download in the
upper right hand corner. (Don't let the "video" part of the title
fool you - it works for other USB devices as well, and my spare USB
mouse can be seen just fine.) This works best for devices plugged into
connectors directly on the computer.

If you see your laser mouse in UVCView, it means the USB chip inside
the mouse, is talking to the computer. But it doesn't guarantee that
the rest of the mouse (laser/optical_array) works.

Thanks - I have tried USBView.

It shows a Standard OpenHCD USB Host Controller (I'll call this 1) and a
Standard Enhanced PCI to USB Host Controller (2), each with 10 ports.

Plugging the mouse into different ports gives different results.
A rear port - it appears under 1. It is recognized as Logitech USB MX510
Optical Mouse. There is a yellow exclamation mark and the mouse does not
light up. Device information says at the top - ERROR no string descriptor
for index 2, and further down: ERROR- No open pipes. Further down under
'device descriptor' there are 2 further ERRORs - no string descriptor for
index 1 iProduct, and index 2 iSerial Number.

A different rear port - it appears under 1. It is correctly recognized.
There is no yellow error. It lights up but doesn't work. Under detail the
following messages could be problems.
Current Config Value 0x01 (arrow) Device Bus Speed: Low
wMaxPacket size 0x0007 = Invalid bus speed for USB Video Class
CAUTION: This may be an invalid bInterfaceProtocol iInterface:
0x00
(note that plugging in a three button optical cordless mouse produces the
same messages, but it works).

Front ports mainly produce the same result as the first described above. On
one occasion, which I can't now reproduce, it appeared under Controller 2,
but showed no lights and the same yellow errors.
Sometimes it shows a yellow error under controller 1 and is not recognized.
No lights, and the main description says Failed Enumeration: Unknown Device.

Does any of this help?
