The onboard USB controller must be enabled in BIOS setup first. Yes, there is likely a disconnected USB header onboard.

Now the card must share the same IRQ as the onboard controller. Move the card to PCI slot 2 or 1. In BIOS setup, enable "Reset Configuration Data" or ESCD.

Boot up and go to MSINFO32.EXE > Hardware Resources > IRQs and check for proper sharing.

: Okay, I have a fairly major, VERY irritating problem. My PC is a K6-2 333

: with 32MB of RAM and two hard disks (a 4GB and a 2GB). The bios was updated

: when I installed the new K6-2 processor and shows support for USB (enable USB,

: assign IRQ etc..)

: My computer doesn't have any built in USB ports, but I need some for an MP3

: player I have. I bought a PCI USB card (Trust 2 port USB PCI card, based on

: the Opti type from what I can tell). My operating system is Windows ME (or 98

: if neccesary, i.e I can reinstall).

: Now, the problem is this. I initially installed the card without editing the

: bios. The card went in okay, was detected by Windows, but then displayed a

: yellow exclamation mark with a 'code 10' error. Which I believe is supposed

: to mean an IRQ conflict. I removed the card and ALL my other PCI card except

: the graphics card, reformatted and tried again. I still received the code 10

: error. I checked the system properties and it wasn't clashing IRQ with any

: other device.

: Perhaps it was because I had IRQ steering disabled (for some reason, when

: enabled it makes my computer lock up whenever I try and install my sound or

: modem cards). I enabled IRQ steering, and it reported all was okay (with the

: steering). I then installed the card again. Still a Code 10 error.

: After checking out this site, I edited the BIOS so that the USB keyboard was

: enabled and so that legacy support was also enabled. I then installed the

: card again. For some reason TWO USB controllers were detected and a whole

: host of unknown devices, four I believe, all of which had red crosses next to

: them. There were two USB root hubs detected and two cards, one the Opti, the

: other a VIA card. None of them were working properly (when I attached a

: device).

: I removed my USB card, reformatted and started again. i tried it with 'assign

: IRQ for USB' on and off, but it seemed to make little difference. It seems

: that whenever I enable 'USB keyboard' and 'Legacy USB support' this VIA card

: is detected, even though there are NO devices installed in the computer. I am

: fast running out of patience as nothing seems to work.

: Does anyone know the solution to this code 10 error? Microsoft seems to know:

: http://support.microsoft.com/default.aspx?scid=kb;en-us;Q278289 But my

: warranty has now run out and I don't think they'll be able to help. Does

: anyone know the solution?
