Hi All

To comfortably take measurements from my couch, I bought a 10m ACTIVE USB 2.0 cable extender for the miniDSP 2x4HD, but the unit does not connect to the software. It does work with a short USB cable, but that means I need to stand by my equipment rack to do the measurements. I know there is a limit to the length of a passive USB cable, but thought that an ACTIVE cable should work for longer lengths.

Any ideas why an active cable doesn't work either ? Is it just too long ?

It would indeed be worth to hear more.. WE've sourced quite few ACTIVE USB cables here and they work fine. 
RULE#1: You must make sure that the active cable is USB2.0 and supports High Speed. Many aren't. 

Maybe in the future we could add a known working active cable to our webshop if people find this useful?

So, it works, but acts very weird, but i assume the cable is just a touch too long. I connected the standard cable that comes with the unit to the active USB 2.0 extension cable, plugged it in, and noticed windows detecting the minidsp multiple times with multiple dings ( as windows does when it detects new hardware ). I then saw in the little window that pops up it shows you the status of the USB device. I can see the Minidsp appear, then disappear many many times over, until it eventually settles. Only then can I connect. However - here is the catch - it stays connected for random times and then pops up with a message

"Connection to the DSP lost" or something to that effect..

I reconnect and it connects fine, but will eventually disconnect again with the same message.

Not sure why it does this, but i guess the long cable is to blame, because it does not do this on the short cable.

@ pdeswardt

Which model you got and most important, did you tripple check that it's a USB 2.0 full speed cable? Many of these extension are not. 
We've tested here with 10 samples of the UNITEK brand and had no issue... Some brands might not be too reliable I guess..

Hi Devteam

Not sure which brand it is - i assume it's a no name brand. I don't live in the US, so can's say for sure. It seems to be a USB2.0 high speed cable ( as it's written on the cable ), but like you say, maybe it's not all that reliable.

Can you link to a long extension cable that DOES work reliably ? ( EDIT: I found a local supplier - I'll see if I can source the Unitek Active USB 2.0 Cable from them )
