Audigy 2 NX Keeps disconnecting
 

I've got an Audigy 2 NX that keeps disconnecting for some reason. It will be playing sound normally and suddenly I'll get the device discconected message. It will work for days or hours and I'm forced to do a reboot when it happens, or switch back over to the onboard. The red mute light and the blue power light are on.

System:
Atom 230 on an Intel DG945GCLF (HT enabled)
2 GB
Win XP Pro SP3
HD2400Pro (PCI - no HD audio)
Audigy 2 NX Software and firmware up to date
Audigy is plugged directly into the mainboard USB ports

I've tried a another USB cable and uninstalling the UAA drivers prior to installing the Creative drivers (I had a problem with them when I installed the Realtek drivers for the onboard so I figured it was worth a shot). There's no errors being generated in the system logs to point me towards anything. I don't have anohter system to test it on as my Craptop is only USB 1.0 and my main rig only has Vista/Win7 and I don't even think there's drivers for the newer OS'es. The BIOS settinsg for the USB seem to be correct. I'm trying the last thing I can think of right now, disabling the onboard sound via BIOS.

Bah, ancient tech that nobody really used. :dots:

Could honestly just be the USB header itself or a split in one of the wires etc. Don't rule out something mechanical versus software/driver.

A lot of the time too it could be a firmware issue with the card or even an IRQ issue in your system - which causes your system to juggle the device with another. I know IRQ problems are not as common as they used to be but they can happen, especially with a legacy device.

Try and connect it in all sorts of other USB ports including front panel etc.

But this sounds like an issue between USB 1.0 and 2.0 stuff.

I don't see there being a problem on the mobo side connection wise, it's probably the first time I've even used either of these 2 ports. My wireless mouse/KB combo could be the culprit, I've had NUMEROUS issues with Logitech drivers screwing up things they had nothing to do with in the past, but then again it's a MS combo. Problem is it works for hours or day's so troubleshooting is a bitch. I haven't had connection isssues with either the mouse/kb or UPS that use the USB ports.

POST is extremely slow with it connected in this state, time to open it up.

The only thing I think hasn't been mentioned is the settings for "usb legacy devices"..... If you're gonna open it up, make sure you post a pic or two..... ;)

other is the link or driver intel

I gave it the once over under the microscope, no cold or broken solder connections. It looks like it has a switcher and an couple of linear power supplies on the board so the fact that I don't have the right adapter shouldn't be a problem.

SGS Thompson MC33078 Op Amp's if anybodies curious.

I'm pretty sure the legacy USB support was enabled in the BIOS. I'll do a chipset update though, chances are I have what came on the disk 2 years ago installed.

Still doing it, this time it came back on it's own though. I have now eased off on the hardware sound acceleration and found out which hub the card is on and told Windoze specifically not to stick the port in a low power mode. We'll see what that does.

And the saga continues. I've updated the chipset drivers as well as the drivers for the various other USB devices (KB and M combo and a UPS). I may have caught something thhis morning though. I plugged my vacuum into the same plug as the A2 and the second I switched on the vacuum, the A2 cut out. I think my fridge may also be on the same circuit as it's on the other side of that wall. So I've plugged the A2 into the UPS and I'll see how that works out.
