USB vs CDROM

[Dave VanHorn]

I have a Soyo dragon system, with XP pro installed.

An Adaptec Dual-connect card does USB 2.0 and Firewire for me (not using the
MB USB)

When I burn CDs on my IDE drive, the USB bus re-enumerates, and/or shuts
down.

What could cause this?

Dave, just a thought but when burning a CD you are placing a heavy load
on system resources.

Do you connect an external power supply to your IDE drive?

On a 2 GHz athlon with 1G of ram?
Not hardly.

???
The IDE drive is powered from the PC's 450W power supply.
I only have this problem when burning, not at any other time.

Dave, did you try a different PCI slot?

Maybe you need firmware update for the burner,
check the mfg site.

No, why would that matter?

No, why would that matter?

To allocate a different and possibly unique PCI interrupt to the USB
controller card (so it doesn't share one with another card). There are
only 4 PCI interrupts, so if you have more than 4 PCI slots (regardless
of anything plugged into them) then 2 of those slots have to share.

Have you checked in Device Manager if the CD-R[W] drive is configured to
use DMA mode? Regardless of your processor and memory size, using PIO
modes with even the slow ATA-33 CD-type drive could flood the PCI bus
which effectively chokes everything else down (that is also trying to
access files on your hard drive).

In BIOS, do you have it configured to let PnP allocate the interrupts
(i.e., let the OS assign them), or do you have them fixed in the BIOS
(which the OS will probably override anyway so it might assign them
differently)?

Your Motherboard turned up on Adaptecs knowledgebase. That was one of the
suggestions.
