I have the latest 5.7.4 firmware (no jailbreak) on my PW2. I installed the voice update from amazon. It added a 154MB /voice/ folder to my userstore. I plugged in my USB sound dongle and rebooted. I captured logs with ;dm search command. The only things relevant seem to be:

The LED on the sound dongle never even flickers, nor is there any sound. It might be looking for a different USB sound chipset, but if it can power the amazon sound dongle, and the hacked version, it should at least TRY to access this, I think. Unless the PW2 cannot suppy sufficient power to light an LED?
