This Logitech USB headset previously worked perfectly on my Toshiba netbook, running siduction:
[85739.178385] usb 1-1: new full-speed USB device number 6 using uhci_hcd
[85739.577677] usb 1-1: New USB device found, idVendor=046d, idProduct=0a01
[85739.577681] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[85739.577684] usb 1-1: Product: Logitech USB Headset
[85739.577686] usb 1-1: Manufacturer: Logitech
I can't say for certain which previous kernel version it was working with -- I had not used it for perhaps 6 months or more, and just tried it yesterday. Now it will connect briefly, then becomes unconnected before I can do much with it. Here is what I see in dmesg (after the above connection):
[85739.613706] ALSA mixer.c:1301 usb_audio: Warning! Unlikely big volume range (=464), cval->res is probably wrong.

[85789.336944] hub 1-0:1.0: unable to enumerate USB device on port 1
My google-foo is not helping much -- I can find the ALSA USB device driver code and references to "buggy Logitech devices", but no real explanation of what is wrong, or whether it is fixable.
Anyone know anything about it?
Thanks!
