Thank you, I had no idea

Actually did not install any driver. I thought a driver was needed for the newer version. Anyway, which one should I install?

I received my DI last March so it was previous version DSP-3 usb input only and had not use until now. Hooking it to my laptop windows 7,  I get the message "One of the USB devices attached to this computer has malfunctioned and windows does not recognise it. Same message in all three ports...

Case closed   Thank you Kingwa.

Thank all. Kingwa said something similar. It is probably the higher voltage. On the other hand the DIR9001 cannot handle the 192K from M2T regardless the material. Case closed

I did all this Denys but still no. I actually repeated my prob in adjacent thread and another member (Scannon18) experienced this issue (page 101) and was forced to run the NFB-3 through USB input, which is a pity of course.  

You can try pureplay downloadable here  http://www.purediy.gr/downloads/pureplayer.zip   It has less facilities but for serious reproduction it is recommended. This is actually a Greek diy audio and their forum also has an English section. Interested for your opinions.

I was about to order an NFB-2.1 and a friend offered to lend an NFB-3 (96) for audition. It worked fine connected to CD via coax and also fine connected to my laptop via usb cable. However, no matter what, it does not work via M2Tech HiFace (Not the EVO). I use Foobar +wasapi . Wasapi sees...

I just did it but still no music. I uninstalled driver, got administration priviledge, downloaded again, installed run - still no good. Foobar sees the driver, made the choice Wasapi M2Tech HiFace and played 44100 material. I cannot explain.

Thx,   I will uninstall download M2 and install again  

Yes and yes. Tried other programs as well. It looks like an incompatibility of the Coax outpout of M2tech with NFB-3.  

From PC with Foobar runs fine when connected via USB cable. But when connected via M2Tech and RCA no music no matter what the material is. Also tried other programs. Any idea what the prob is Thx
