Win 98 probably needs some drivers installed for these particular USB peripherals ?
Or at least some generic USB driver.

Win 98/ME USB issue

Thank you for fast reply.
I already have USB drivers installed. It looks like keyboard doesn't have voltage in Normal Mode, because even leds are not working (NUM LOCK etc.)

Have you tried different keyboard ?
And what are your USB settings in the bios ?

Different USB port perhaps possible to test, or even a PCI USB card ?

No, didn't try different one as I only have Corsair K70 Low Profile. I suppose this keyboard won't work at all 😀
Will try other normal one as soon as possible.

It's not working on other USB port either.
About external - didn't think about it. Gonna try as I think I have USB bracket in other PC. Fortunatelly this motherboard has connector for it.

Only settings in BIOS are:
- USB Legacy Support which is set to Auto. Other options are Enabled (not working too) and Disabled
- USB Function which is set to Enabled

For my K95 I had to enable BIOS mode, don't know if it's the same for the K70 or not but it should be in the manual. Usually this is needed before the OS loads the USB drivers though.

Enable BIOS mode
Hold F1 and padlock for 3 seconds. Scroll lock indicator should blink.

Due to my KVM (USB to clients) I have to use a dedicated mouse and keyboard for 9x and 2000 otherwise I can't use my mouse and keyboard. Works fine in BIOS and DOS though. Sometimes I can get it to work properly then it glitches out again. Still haven't figured it out. For the mouse it may or may not move and when it does move it barely does. For the keyboard it'll type slowly and then repeat characters dozens of times. heh. Likely a driver issue with the OS and the iogear KVM.

Gonna try, thanks.

Just for the record, I meant something like this 😀

Yeah, I know. Just I don't have a card like this and first I'll try bracket 😀

I think safe vs. unsafe mode is because Windows goes through the BIOS to access mouse/keyboard in safe mode, or at least doesn't do whatever initialization of usb that would cause the bios to stop emulating the keyboard.
For PS/2 ports though, I have an actual PS/2 that had that problem because of a blown fuse and I was able to replace it. I thought newer motherboards are supposed to have self healing fuses.

Can you show what this fuse looks like?

I've tried bracket with USB ports (it's connected to motherboard connector) and even BIOS don't detect keyboard 😁
Have to buy PCI card then.

On mine it was this one. Looks kind of like a resistor and was right next to the ps/2 ports. https://www.littelfuse.com/~/media/electronic … tasheet.pdf.pdf

Thank you 😀
So it's probably this fuse:

Maybe I'll try to change it.

Today I've found and already ordered CUSL2-C (100% working if believe seller 😉 ) for $15 (btw, prices of these motherboards are sick).

Hrm actually I think it's that P110 right below the keyboard port. It's supposed to be self resetting. Can you test continuity with a multimeter? I suppose it could fail to self reset.

Ok, case is closed as I've received CUSL2-C and it's working fine 😀

About TUSL2-2 - PS/2 ports were working when you specifically touched them. Probably some cut soldering or something like that. I still don't know why USB ports weren't working, maybe same reason.

Sounds like broken solder on the TUSL-2. Id be desoldering it and applying new solder.

I'll probably try it and if it works - just sell this motherboard. Or I just sell it without repairing 😀
