PUC2 owners,help needed!

 Purchased a PUC2 Lite-apparently dates from 2009-HW Revision 1.2.
When trying to update the driver(installed automatically when first connected to laptop w/W7),I get a message saying device is not connected,even though the Green light on the PUC2 is showing connectivity.Additionally,my DAC is showing 24?48,even though the PUC2 Lite is supposed to output 24/192.Maybe the driver needs to be updated in order to pass 192?
I have only one 3.5 mm in-yellow colored with a circle with a triangle at 9 oclock pointing to 3 oclock.Is this in meant for a 5V input,or is it the zero latency output?It was sent to me without a USB Y cable,so I am not yet able to listen properly.With 1 USB cable connected from the PC,sound is so-so.
Your help appreciated.

 Took me all of 2 hours to succeed in updating the driver,now 192 is recognized on the DAC.
I am still in the dark on how to input 5V 1A,so as not to have to use an inferior USB Y cable.
What does the yellow tipped/encircled 3.5 mm(the only 3.5 mm input) serve as?Thanks for your help.

 Found it-the only input on my PUC2 Lite is to regulate the zero latency function.I have a short USB which is good quality,but the PUC2 Lite does not sound good with only 0.5 A fed to it.Is there any way that I can still use the good Wireworld cable between the laptop and the PUC2 lite input while still being able to add on a 5V feed from a Teradak PS,so that the PUC2 is amply fed?Otherwise I would have to use a cheap USB Y cable,and that would nullify any sonic gains to be achieved with the PUC2.Maybe worth a try,in any case

 ou will need to dismantle the PUC; disconnect +V into the usb socket, and install an external power socket into which 5V can be fed.

Should not be difficult but you should use a very good power source and not one of these cheapish web purchased units with LT or LM chips.

 Appreciated!If I understand correctly-take away the 5V supplied via laptop's usb,and reroute to a new(drilled)3.5 mm. socket.Maybe the zero latency 3.5 mm. socket,which I have no plans to use,can be rerouted internally to supply the necessary 5V 1A?I plan to use a small Teradak.Thanks for your advice,Raanan

Hi !
just to say if you find a solution please post.
I have the simple PUC2, non the Lite version.
I am using the adapter cable from Teradak to power it.
Strangely i have found a cheap usb charger that I like with it.


Kind regards,
bg
