Yes, I tried last night and it's working, but only from the usb input.
Form the usb card I have no sound.
I just tried again and the same. Of course everything was turned on before I start the PC.
I should try maybe a diferent slot for the usb card?!

its 48mhz 3.3v level to xmos and 24mhz from ff at 3.3 v levels to usb hub
i had assumed if i put in 24mhz in to xmos without programing it would either not work or play at half speed
ill try a 24mhz before i fit it to the soekris just to see what happens
Sorry, yes, I meant 48MHz to XMOS - I don't think 24MHz will work without programming the XMOS
ive it running on a pcm5102a for testin and sounds pretty damn decent although not the same natural sound as the r2r
a good tight detailed snappy sound, timings probably improved over the other front ends ive heard on this dac
no neg effects so far and must be playing a few days now non-stop
Great, sounds very promising
seems a little more crisp and assertive at 3.3v levels on soekris
will give it more time

Wonder what the difference is between this and the REGEN?
Hi Rick, got one purely for its isolation claims and it seems to work well so far, I had the Giso Isolator previously from my JPlay dual PC days for Ethernet Isolation between PC's and it also worked well so this prompted me to purchase.
Some pics below:
Thanks for the pics, Pearse - very interesting
This device is regenerating the USB signal so it effectively does the same a the Regen but I see some potential weaknesses in that part of it's functionality
I can see that the device uses Xilinix FPGA to do the heavy lifting although the two chips (are they from FTDI?) between the FPGA & USB ports I would guess are responsible for translation to/from USB signal protocol. I see the isolators between the two sides of the board (giving 8 channels in each direction) & also the coilcraft transformer spanning the two sides of the board which I presume is responsible for the isolation of ground & +5V but I can't see how this can really provide clean PS on the other side - it is 5V on primary & 3.3V on secondary side - also the spec for the Intona says "Powered by USB host device; internal DC/DC converter for isolated side" - this whole PS area, I expect is a possible weak link although it appears to be helping SQ by isolating the other pathway for noise transference, the USB D+ & D- data lines
If the "clean" side was powered by a good PS supply, I reckon there would be some improvements. What I also don't see is a clock on the board but there is one black block that might be it ( I can't read the ID) - a decent clock with good PS might also be an improvement, I reckon.
But all very interesting - thanks for posting, Pearse

For Digital Audio playback that delivers WHERE the performers are on stage but more importantly WHY they are there.
I have the Intona before the Regen so just for the Isolation but as you say if it could do a good job of regenerating USB then maybe no need for Regen.
Below is probably the chip you are referring to and the other 2 pictures maybe help you are looking for clock, i could not see anything!!!
