USB Headsets vs PCI SoundCards
Mandrake & ALSA

I current have a standard PCI soundcard, installed with up-to-date cirus drivers.
I would like to install my Plantronics Headset but i come against a bit of a problem, heh.

When the USB Headset is plugged in, Linux will not start, (it freezes during boot, sometimes during usb module dependancies loading, sometimes not).

I have tried playing around with ALSA a bit, with no success.

I have followed this thread too.

Im running out of ideas.

I have booted the system without any USB except the headset, with all of them etc.
I managed to get it to boot with it installed on one occasion, but i couldnt use it or see it with usbview.

Operating System: Mandrake Linux 9.2
USB Headset: Plantronics DSP-400
USB Mouse: Logitech MX700 Wireless

I have a USB2 5port PCI card installed too, i have tried removing all appliances from that too.

Please help :)

Well, with ALSA installed correctly and my kernel updated, i can now see "USB AUDIO" uder ALSA in XMMS output preferrences, if i plug the headset in while the PC is running.

But when i select this device i hear nothing more than a squelch.

Once it said "unable to install hw parameters"

It also now appears under 'usbview' as....
