[SOLVED] Logitech Headset not recognized

jlinkels · 01-08-2011, 08:22 PM

When I plugged my Logitech Headset into this computer, it wouldn't produce any sound. Checked /etc/asound, /proc/asound/cards, etc. The headset would turn up as a USB identifier instead as of "headset".
That made me check /var/log/syslog first:

Code:

No good eh?
Strange, because I had been using this headset on a Debian Lenny laptop, and my son was using such a headset on his Debian Sid computer.
After two hours of googling.... (this error was mentioned often, but never resolved), I plugged in my son's headset, and voliá:

Code:

Then I took a new one from the package, (thankfully I prevent disaster and bought 3 of them) plugged it in and it worked as well.

Conclusion: hardware defect. It is unlikely, but you should not exclude the possibility.
BTW lousy quality, only 6 months old, and Logitech is supposed to be one of the better brands. Unfortunately postage for warranty return will be more expensive than replacing.

So the final determination was that the headset was damaged? Another identical headset on the same machine worked fine?

Definitely.

I tried one used headset, it worked. Then I took a new headset from the packaging, it worked as well. All three headsets are identical, purchased in one batch from amazon.com. The defective one had been attached to one of my laptops (Debian Stable) for some weeks.

Of course it is uncommon that the USB device identifies itself and then refuses to communicate. Since this might be caused by a USB connection which can receive but not send, I tried to plug in the headset in all USB ports which were working as I had other devices connected.

For the record I will reconnect it to the laptop I mentioned, and then I'll perform an autopsy on the defective oen to see whether it is a cable defect. Although I believe the USB logic is in the plug, so there is no chance for a cable defect.
