>Description:

When NetGear USB Ethernet device is plugged, sound (in amp, xamp, Real Audio
Plugin, mtvp, ...) stop working. All applications are 'looping' on the first
sound frame downloaded to the OPL chip. No kernel messages are logged.

Other sound fucntions seems to work (volume, balance, mixer, ...)

As soon as Netgear is removed, everything is ok (no need to reboot).

As far as i can see, no IRQ nor hardware ressources are in conflict.

>How-To-Repeat:

I have only this USB device, so i am unable to check if this is 
a general problem with USB code or just NetGear.
