Logitech USB Microphone (AK5370) not recognized
I have a logitech microphone, that usbview/lsusb reports as AK5370. By all accounts, the snd-usb-audio should be loading when I plug this in, but it doesn't budge. No driver is loaded, and thus the system doesn't recognize this as a microphone. Does anyone know why this might be so? Here's the output of lsusb:

Re: Logitech USB Microphone (AK5370) not recognized
Just a hunch:
From make menuconfig of the 3.5 kernel
CONFIG_SND_USB_AUDIO: │
│ │
│ Say Y here to include support for USB audio and USB MIDI │
│ devices. │
│ │
│ To compile this driver as a module, choose M here: the module │
│ will be called snd-usb-audio. │
│ │
│ Symbol: SND_USB_AUDIO [=y] │
│ Type : tristate │
│ Prompt: USB Audio/MIDI driver │
│ Defined at sound/usb/Kconfig:12 │
│ Depends on: SOUND [=y] && !M68K && !UML && SND [=y] && SND_USB [=y] && USB [=y] │
│ Location: │
│ -> Device Drivers │
│ -> Sound card support (SOUND [=y]) │
│ -> Advanced Linux Sound Architecture (SND [=y]) │
│ -> USB sound devices (SND_USB [=y]) │
│ Selects: SND_HWDEP [=y] && SND_RAWMIDI [=m] && SND_PCM [=y] │
│ This module is turned off in our kernel by default. I could be wrong, but you may want to build the kernel with this module enabled and see if it helps.

Re: Logitech USB Microphone (AK5370) not recognized
The solution is a kernel build?! Yuck.
Is this a recent change? I have arch running on my netbook (a fairly recent build) that resolves the driver just fine. It must be something that has been turned off recently?

Re: Logitech USB Microphone (AK5370) not recognized
As I said, it is just a guess. You had not mentioned that you had a different Arch install using the device.
You might try looking at what modules are loaded on the netbook versus those on the machine in question.
Besides? What is so yucky about a kernel rebuild ? (Hint: I use Gentoo as well as Arch 
)
