Solved Onboard USB Ports Not Working

April 21, 2012 at 05:26:23
Specs: Windows XP, Pentium 4 / 2 GB
My onboard USB ports stopped working so I got a PCI USB hub as a walk-around. It's all fine except I can't get into the CMOS BIOS because the PCI USB hub isn't recognized immediately upon Mobo boot up. This PC has no onboard PS/2 ports unfortunately.

I need to install a fresh OS (Windows XP) and to do that I need to boot up from the DVD driver. But without the keyboard at boot up, I can't press F12 or Enter, etc.

BTW, the onboard USB ports do carry power as I could use them to charge my Wii remote etc.

Am I hosed? Any suggestion?

After the CMOS is reset, you will have to immediately access the BIOS to correct the date/time & numerous other settings.

Here's a suggestion - shutdown the system, then temporarily disconnect the HDD & remove the USB card. Connect the keyboard to one of the rear USB ports, do NOT connect a mouse or any other USB devices. Boot the system & immediately begin tapping the BIOS access key (Del, F1, F2, etc) & see what happens.

If it doesn't get you in, shutdown & reconnect everything as it was. Then, rather than reinstalling Windows, try a good old fashioned manual cleanup - delete, uninstall, run a cleaner, MSCONFIG, scan for viruses/malware, defrag, etc. In other words, all the things you should be doing regularly all along.

Why do you need to reinstall Windows?

If the onboard ports still carry power, they should work. Could it be a driver issue? Have you tried accessing the BIOS using the onboard USB?

Are you saying that none of the onboard USB ports will work or allow you to get into the BIOS ? How many ports are there ? If that is the case, you might try resetting the BIOS settings to default by removing the CMOS battery(or moving the jumper if necessary).

The onboard USB ports (2 in front and 5 in the back) got flaky for a period of time (with the USB system tray recognizing and losing USB devices repeatedly), and eventually they just died totally. I got the PCI USB card as a walkaround and that almost didn't work because when I booted the mobo would flag keyboard error and then stop. I repeatedly powered on and off and somehow and finally it proceeded to Windows OS. I dare not power off ever since. After almost 2 years, my system is really polluted. Bogged down often on simply operation. DVD movie would take 1-2 minute to load, etc. I would really like to install a clean OS and start over.

The onboard USB ports are NOT working. There is no way for me to access the BIOS. Or press Enter to boot from CD...

I remember resetting the CMOS as option of last resort, but that was before I got the PCI card to work. Since then I have more to lose. If after resetting, the mobo prompts me to press F2 or other key, I'd be hosed, rendering my PC totally unusable.

Does anyone know the chances of having to press a key after CMOS is reset?

Oh that's right - time and date. Sounds like I have to hold that off till the day before it's declared dead!

Tried your suggestion. Screen prompted SATA 0 & 1 error and to press F1 or F2. Key board didn't work, so no go there.

Ideally then, if I can only borrow a Dell XPS and pop my HD to have the OS installed, and then pop it back into my setup, that would have worked.

In the mean times, I'll have to clean up. It's unfortunate that even to just "repair" the OS, I'd have to boot up from the DVD drive. And why do they require a key press to proceed to boot from the DVD drive, instead of timeout?

Thanks for your trying to help. Much appreciated.
