I just got mine today.
It installed as Teradak 96K usb audio. I can't get kernel streaming to work - Win XP SP3, Foobar v0.9.6.9. - says it is ks usb audio but won't stream data. It allows 16, 24 and 32 bit settings but none work and 32 bit gets an error message. KS works with my laptop Realtek chip but not with the Teradak.
So, I'm using asio4all. This says it is 8-96K 24 bits. There doesn't appear to be any way to control this device. I really hope Teradak come out with their own asio driver as promised.
In the properties box in windows, it says it also has a line in and an spdif in but there's no hardware to support this afaics. There is a solder point on the board for spdif in so maybe that'll be worth investigating for anyone so inclined.
I'm gonna leave mine to burn in for a week and then see how it is. My first impression is that I hope it improves, but then that's always true eh !
The regulator near the usb is dropping 5v down to 3.3V but I think this is just for Tenor chip.
The unit arrived in bubble wrap with nothing else, not even a box.
EDIT : Just checked the voltage drops over the LT1084 with a 9v supply. Pins 1 and 2 have 1.244V (adj to out), Pins 1 and 3 are 5.2V (adj to in), and pins 2 and 3 are 3.98V (out to in). I can see two resistors connected to the left of the reg = 300 and 100. So it seems that the ref voltage of 1.244 is multiplied by 300+100/100=4 to give a 5 volt output. The datasheet says the dropout is less than 1.5V so really it should be possible to feed this device anything above 6.5V regulated and it'll work quite happily.
I checked the underside and there's just a few resistors.
