USB "Unknown device" for Cordless Intellimouse Explorer

Motherboard:
Epox D3VA VIA Apollo Pro133A chipset

CPU:
Pentium-III 1Ghz

RAM:
256Mb SDRAM PC133

Maybe something is wrong with the mouse and or the receiver

Umm you do have the batteries in it and properly seated?

You might want to check out this page to see if you these files for troubleshooting your device

BTW Have you opened the Device Manager and see if any conflicts are being listed there? Are there other devices hooked to the USB and are you connecting directly to the USB port or a USB hub?

No, the mouse works fine until Windows installs the USB. If I set "Assign IRQ to USB" to Disabled in CMOS the mouse works ( although not as accurate as it should ), it's being installed as a generic ps/2 mouse. I could say fine and be satisfied with this, but I've not paid $70 for a generic Ps/2 mouse with no scroll function and poor accuracy. It SEEMS to me as if Windows powers down the USB or something like that since the reciever turns off the LED, so the problem should probably be focused on the USB and not the mouse.
No other devices are connected to the USB.

USB detects an "Unknown device" when the reciever is plugged in, however it refuses to accept any other drivers for it.

The reciever is directly connected to the USB port

Hmm you do have your BIOS set as plug and play? Perhaps the receiver has a faulty chip or was misprogramed to be plug and play. The hardware setup won't let you choose which driver to use? Does it go through and install something and then in the Device manager there is an entry as Unknown Device. If so you should be able to do an update of drivers through there.

The BIOS is set to "Plug n play OS: Yes" and also Assign IRQ to USB and Onboard USB to "Enabled". The hardware setup just detects an "Unknown device" and it looks like its installed correctly ( no red or yellow marks over it ), but it uses no drivers and when I try to Update the driver, the only thing I can select is the same "Unknown device" the the USB icon regardless if I deselect "show only supported devices".

As I've stated before, if the USB isn't installed the green LED on the reciever is lit all through the boot up, and the mouse works ( though on default drivers or something ), however if USB is installed, the recievers LED shuts off before the GUI boots up, and it seems to get no power from the USB port. Also if I check the USB port properties in the Device manager the "Unknown device" gets 0 mA

I just tested the mouse in Linux ( same computer just different hard-drive ) and it worked perfectly

Did you install the 4 in 1 chipset drivers for your mobo (the VIA chipset)? it has usb drivers which may help the problem

I've installed the latest 4-in-1 drivers and USB filter 1.10

Well then I would say that there is something about the receiver and USB combination that XP doesn't like. It still could be soemthing to do with the reciever even though it works on the Linux settup. Apparently XP just doesn't understand what the device is for some reason when connect to the USB port. I am presuming you have more than one USB port and you have tried all the ports.

Have found that this error "unknown device" in any Windows operating system (not just XP) generally means the device is not generating enough power. Try another set of batteries.

are there drivers for the reciever and xp?

I failed to solve this issue, so I've returned the mouse =(

Hmm maybe you could of asked the vendor to exchanged it with another one like it to see if the device was defective for running on XP. It has been known to happen. A device works fine on one OS but doesn't on another OS even though it is rated to run on the chosen OS's. I have had this happen a few times and exchanged the device with the vendor low and behold the device would work. It is like automobiles, some devices are lemmons.

This sounds very similar I had with Windows XP and VIA chipsets. Even with latest drivers for the USB, and USB Components, it would not allow the use of my scanner, printer, or webcam. My Digital worked quite well with my USB. After endless searching, email with motherboard manufacturer, award bios tech support, microsoft, and my USB product manufacturer's. That I should flash to newest bios. After some thought, and easier and less painfull answer came to me. I went and bought a PCI USB Belkin card for less than $20 came home and within 15 minutes all USB items were installed and working. My 2 cents. And no I do not believe it is your batteries. Or chances are that it would have shown same indications in Linux. Thanks for your time and good luck.
