Audigy 2NX USB Root Hub Prob

Question

Hopefully someone here will have some suggestions to help resolve my issue.
I have fi've USB Root Hubs on my computer; the USB system is 2.0
Only two of those hubs are in use. One hosts my Canon scanner.
The other hosts every other USB device on my system.
That in itself is an issue, but because not all of my USB devices are in use simultaneously, it hasn't previously been an issue.
Now, however, it has become one.
Both my Audigy 2NX and a four-port self-powered USB 2.0 hub are on one USB Root Hub. The four port hub has my two printers connected to it.
The issue is that when I use my laserjet printer, it disables the Audigy 2NX. The Audigy normally comes back up after the printer has gone back into sleep mode.
However, if I am playing a game when the printer is used (I share it on a wireless home network) it disables the Audigy and it can only be brought back up by restarting the computer.
I think it is one of two issues;
. The four port hub with the printers on it cannot share a root hub with the Audigy 2NX; when the laserjet comes out of sleep mode, it uses all of the bandwidth on that root hub and disconnects the Audigy.
2. A recent driver update to the Audigy is conflicting somehow with the printer.
I might also be tempted to think it was a power supply issue if I didn't have a robust 650 watt PSU on my system.
To try to get the two devices on separate root hubs, I turned off my computer and disconnected all of my USB devices. Then I connected one at a time, powering down in between connections.
The device assignment remained the same.
My next step is to uninstall the Audigy 2NX completely from my system, and then re-install from the base drivers.
My question is; does anyone know how to force devices to install to a specific and/or different root hub outside of their physical connection? An .ini edit or perhaps a driver edit's
Thanks in advance for any help.

Answer 1

I have an Audigy 2 NX myself, and I found it works best off of a direct root usb port (not off a hub). The problem is that on most computers 2 USB ports share hub. Which is why you are having that comflict.
My conflict doesn't happen there, it was on the mouse at first, now it's on an external IDE Adapter i'm using.
All I do is unplug the IDE adaptor when it stops working, waiting a few seconds, then plugging it back in.
So what I suggest is to do like I did, and switch what ports things are plugged into until it's something that can plug & unplug with no real issues.
Why this happens, in opinion, is that there just isn't enough power getting to all the usb ports when there's alot of stuff plugged into them. My limit seems to be 7 items, even though most of them are lower power stuff, mouse, joysticks. I do have a 3.5" hd in a case, which is self powered, and the ide adaptor which is self powered, and the audigy 2 nx, which is, as you know, self powered. I can plug another item in, but anymore after that will knock my ide adaptor. and i still have usb ports i'm not even using. oh, the joysticks are on a hub which is where I usually plug another item in, either my mp3 player or thumbdri've.
I think it most likely an electric problem, and that it only affects people with faulty usb componets or something. I haven't heard of it being widespread or specific chipset/usb controller problem. Can't think of anything else it could be, but i'm not an electrition.
Sorry i could be of much help, but maybe you can at least make it less of a bother to deal with.
good luck
