I pretty much got the same messages. This makes me wonder whether the PW2 hardware actually supports OTG in general and usb sound cards in particular. (I know that it has the required drivers.)

On the off chance that we both happened to have bought a usb sound card with an unsupported chipset, can you please post the lsusb output for your device.

Mine is:

Code:
Bus 005 Device 010: ID 0d8c:0014 C-Media Electronics,. Inc.
If you currently don't have access to a Linux machine, plug your sound card into a Windows machine and get the vendor and device ids from the device manager driver details dialog box. For example, it reported the following ids for my sound card:

Code:
USB\VID_0D8C&PID_0014&REV_0100&MI_00
BTW, my USB sound card doesn't have a LED so I can only tell whether it's working by listening to the headphones.

@knc1:
On full-blown Linux machines I can use modprobe to load device drivers; does the Kindle have a similar mechanism?
