I have a piece of audio recording equipment hooked up to the firewire card in my PC. The equipment suddenly doesn't work, and my "MCP Audio Processing Unit" has this warning message in the device manager (I'm using XP):

This device cannot find enough free resources that it can use. (Code 12)

If you want to use this device, you will need to disable one of the other devices on this system.


Its location is: PCI bus 0, device 5, function 0


Does anyone know how to determine which "other device" should be disabled? I don't know how to interpret the meaning of the location values. I tried disabling a few unneeded devices, but no luck. Also tried uninstalling/reinstalling drivers.

Thanks in advance for the help!
 
In Device Manager, does it show an IRQ conflict? Hopefully, you can disable the conflicting device. If its an IRQ issue, you can change those values, but if its an IO or DMA conflict, try restarting with only the stuff you need connected to the system.
 
You know, I'd never actually sorted the devices by Type to look for a resource conflict that way. Your suggestion made me look a bit closer though - I'm at work so I'll take a better look when I'm home. I apprciate the help!
 
Well, I didn't find anything in the BIOS that looked helpful as far as resolving the resource conflict.

Also, there's no IRQ or I/O or memory conflict that I can find. Its memory address range isn't in use by any other device. It doesn't even have an IRQ assigned to it. The troubleshooter doesn't help because it either assumes I can see which device is conflicting with this one (I can't find one), or it assumes that I can use the Change Settings button to reconfigure my resources, which I can't. That button/area is dimmed for any device I look at.

I thought it might help to disable one of the devices I didn't need on my IRQ list and then reboot to see if my recording device took up the available channel, but I didn't see anything that looked unneeded. How many devices can normally be assigned to one IRQ?

Depends on the device.
Try googling the address range/IRQ being used by the conflicting device and see if the search continually lists a certain device. This will help with determining what device is conflicting. Then update the driver first and try to reassign different resources last. <- to the part that doesn't show a conflict

(the following comes from an old tired mind so please be gentle if correction is needed)
I seem to remember that resources for devices can be altered by using different controllers or plugging the controller into a different PCI slot. So... Try moving the firewire controller card to a different slot if it is not integrated. And if you get really really stuck than buy different controller card from a different manufacture that utilizes a different chipset. It would be worth a shot due to the low cost of a new card.
