I have just received a socket 7 mainboard, where I suspect the onboard USB to be broken. I just don't know how verify that conclusively.

Installing Win98se does recognize and load the USB drivers.
Sticking a mouse into the usb port will make the mouse LED turn on red. So power is supplied.
But other than that, nothing happens. I tried a mouse, a USB stick and a usb card reader.
I never got a reaction, like reporting a device or asking for drivers.
I am not sure if this is normal.

Even more alerting is this: If I have a usb mouse or keyboard (35 mA) hooked up to the usb port during power up, the computer will turn the screen on and display "Pentium 233mmx CPU found". And that is all it does.

I activated USB in bios. Windows responds right away by providing drivers when it is activated. Is there any other setting in Bios that I need to check?

If stuff starts to go wrong at POST, you can rule out software.

How 'onboard' is this? Is it an ATX board with ports on the actual motherboard, or is it an AT board with headers you've attached external ports to via a flatcable. If the latter, it's possible the pinout doesn't match (a common early USB issue). Power seems correct, otherwise you'd have had less LED and potentially more smoke, but possibly the signal pins are reversed, or GND is somewhere else.

THIS^^ onboard. Actually, the mouse LED goes on right away. When I do the same in my other S7 board, it takes time to go on.

Which motherboard? Are there jumpers for things like +5VSB? Do all the ports on the board behave the same?

Gigabyte GA-586STX2
No jumpers except for bus, cpu multi, voltage.
All two ports do the same.

This vague answer is not helpful. I looked up the board and they are just headers and not on the board itself. However, the pinout is standard.

You sure?

Looks like ATX I/O including USB...

...which is bad news, as a pinout mismatch would be easy to fix. In this case we know it's not software and as behaviour is the same on both ports, it doesn't sound like a damaged port either. So either BIOS is thoroughy borked for USB (if you're running anything older than 1.6, try this one: https://www.gigabyte.com/Motherboard/GA-586ST … support-dl-bios ), or there's a hardware issue. I'd check the SMD components immediately behind the USB ports for shorts or broken/missing bits.

Agree ! Most likely a board or bios issue.

Can you post a good picture of your board please ?

I remember that certain Socket 7 motherboards actually had USB 1.0 and not 1.1. Sometimes, they weren't compatible with newer USB hardware, and even a plain USB mouse from the mid 2000s would fail to work on them.

Not sure if that's the case with your board, just thought I'd mention it as another possibility. See here for more info: USB 1.0 (1996) vs. USB 1.1 (1998)

PC#1: Pentium MMX 166 / Soyo SY-5BT / S3 Trio64V+ / Voodoo1 / YMF719 / AWE64 Gold / SC-155
PC#2: AthlonXP 2100+ / ECS K7VTA3 / Voodoo3 / Audigy2 / Vortex2
PC#3: Core 2 Duo E8600 / Foxconn P35AX-S / X800 / Audigy2 ZS
PC#4: i5-3570K / MSI Z77A-G43 / GTX 980Ti / X-Fi Titanium

Again thanks for all the replies.
Board and USB port.
I am on bios 1.6 iirc, I do get 32GB HDD size.
Board is likely from 1997. So this may well be USB 1.0.
From the linked thread, there are other boards with similar issues.
Oddly though, the bios offers to use USB keyboard. (I guess this is legacy devices elsewhere)

I am trying to set up a USB2.0 card on the board, but again, I get no functionality. I need to recheck with a 100% working card.

I checked the SIS 5582 datasheet and it does say USB 1.0....

Looking at the board photos it kinda looks like the USB data lines go to & through FB1,2,3,4 to the main chip.
doing a resistance or continuity test on these FB components, they should all measure close to zero ohms or zero voltage drop.
Now for differential pairs those lines do look a bit odd but meh.
USB0 B21+ E19-
USB1 C21+ A22-
measuring continuity from the usb connectors to these points is only doable for A22. B22 might be possible given some thin magnetwire and some luck. 😀
A21 48MHz USB clock
verifying if this clock signal is there and the right clock is also possible.

my 2 cents. Good luck

Right to repair is fundamental. You own it, you're allowed to fix it.

1.2 Ohm each.

Isn't USB 1.0 for HID devices only or something?
