How about DS, same problem?

try a powered usb hub

Trying it on a different computer will prove whether the problem is the USD or your PC. What's your PC make/model? Some USB 2.0 chipsets are not as good as others - standards, eh!

Have you anything else running off any other USB port on the desktop - external HDD, etc, that might effect current draw on the port?

Thanks for all the suggestions.

Haven't tried DS yet, but if the device doesn't work with ASIO or KS, then it isn't really useful imho. Testing now... doesn't work either

It seems to be even worse.

Only other thing connected to USB on my computer is a mouse. I'm using Asus P5Q-E (Intel P45 chipset) motherboard. Never had a problem with Stello DA100's internal USB implementation on this motherboard. Right now, I'm using Musiland -> MSB Power DAC though, which is causing many problems... However, motherboard's digital out -> MSB Power DAC is fine.

I'm guessing here but the total current draw on the USB might be too great - can you try running it without the mouse plugged in?

Stello may have had less current draw, I don't know?

Found this in realation to USB on that M/B http://www.tomshardware.co.uk/forum/...3589_12_0.html where it reports a problem on USB power: Quote:

- USB headers are underpowered. I can no longer download from my digita SLR from my front panel USB port. They worked fine with my old A8N-SLI Premium board.

Is this the same motherboard ?

The mouse isn't on the same port. It should be independent of the Monitor 01.

Thanks for looking into it

My board is from the same line, but better than the P5Q Pro. In the thread, he mentions that the rear USB ports are fine. I'm using the rear USB ports on my mobo.


I noticed that Foobar 0.9.6.9 just came out today, it didn't help either :-/

It doesn't matter if the mouse is on the same USB port or not - I think it's the total draw across all USB ports that counts - try running without mouse to prove/disprove!

Anyway, look at that link I gave - read down through the thread - lots of people reporting USB power problems on that m/b!

Stello has external power supply. I would try powered hub suggestion.

Aha! But what does Quote:

mean then?

 

[some1x]

Don't want to jinx it, but it seems to work fine on my laptop. Thanks again for the help.

Oddly enough, the USB specifications for the Monitor 01 says it only needs 100mA of current...

Now I just have to decide whether its worth keeping this and buy a USB hub or try to find another USB->SPDIF solution.

 

[mmerrill99]

Give us a quicky review of how it sounds compared to the Stello (which is about *10 the price & pretty highly rated, I think)?

 

[some1x]

They cannot be compared. Stello is a USB DAC (with SPDIF inputs also), Monitor 01 is a USB to SPDIF converter...

 

[DoYouRight]

A powered USB hub costs like $15 don't discredit it and it runs on your laptop hows that sounding?

 

[mmerrill99]

Oh, OK, but can't you feed the SPDIF from the 01 USD to the Stello & compare it that way - test it out as a USB->SPDIF transport? Just wondering?

 

[some1x]

I could, but I got this to use with my MSB Power DAC

The Stello will either be moved to a different system or sold.

edit: ooops. Just got the pop again :facepalm: its offficially hopeless. Seeing as how there are new options for USB->SPDIF converters are becoming available every day, I'm gonna return this. Up next is Tascam US-144 (async and high-res also), Audio-Gd Ref-3, HagUsb, or ???
