being a pc technician, I have seen this happen quite often, esp. with laptops that don't have the power to fully power the usb ports and was wondering, this usb hub you said you are using, is it passive or powered.....if you are using a passive hub(not powered by a actual ac adapter) then I would suggest swiping it out to a powered usb hub.
It sounds like to me, the mixer is not getting enough juice to stay powered up through the usb and by what Robert said, try plugging it into a usb 3.0 which has more of a power output than the older speced usb 2.0 and below....
I hope this helps...
 

I reckon you finally pointed me to a weak spot in my setup ... that hub of mine is indeed passive and so far I never cared because it worked (and of course, I hadn't deactivated the USB power optimization option, either) ... that I can imagine compromising the stability of the digital mixer ...
 
Action plan:
 1) update all drivers => DONE
 2) disable USB power optimization => DONE
 3) get a powered hub
 4) get a UPS
 5) test, test, test in various places ...
 6) pray for it to work
 
 
 
 
 

I just ran out of time : disable USB power optimization => DONE      Perfect your well on your way !

of all "strange" behaviours I have encountered, this is definitely the strangest ... and it just returned - thank god, not at a venue but back home where it is a "controlled" environment and fully reproducible ...
 
hence, ...

• definitely no power issue
• all measures discussed above are implemented (active USB hub, power saving options off, all latest drivers & firmware)

the good thing is that it is totally reproducible, yet I'm running out of ideas what to try ...

• about EXACTLY one minute into playback, something happens in the OS (win 8.1) that causes the X32 digital mixer which is connected via USB to reboot (crashes with message "target.cpp: 94") - it's always at the same measure + beat (25:04:something)
• if I start playback at a later point in the song, it happens after the same elapsed time period ...
• if I stop playback before e.g. at 20:xx:xx, RTZ and start again, it happens at about measure 5 ... same elapsed time ...
• hence it's not a problem of the Sonar project ...
• it's not a latency issue, either. "latencymon" reports low latency at all times and does not show anything su****ious, also not during the critical "time" period in the song ...

 
what makes it really strange ...

• it has happened almost 2 months ago, then was not reproducible when trying to figure and now it's back ...
• in the periods between it worked just fine
• what's common to both events is that win 8.1 reported that a windows update would be available, which I did not allow it to install because I don't want my system changed a day before an event ... but how could that possibly be affecting it???
• something is happening in the background, there is a small spike in the task manager CPU performance (going from flat 5% to 12% when it happens - yet I have no idea which service is actually causing this. how could it track that down???)

BTW, ...

• the DAW is offline
• there are 4 warnings and 1 info in the event viewer at the exact time when X32 reboot is triggered (see next post)

Any idea on how to track this down is highly appreciated!!!
 
Thanks a lot in advance.

Is there any possible chance some scheduled task is running periodically?
 
(Sorry I was so far off on my earlier post - I was reading in a hurry and feel like a complete dope - DOH!).
 
Rereading things, it sure looked like some sort of power issue - I have had instances where there was just REALLY CRAPPY stage power - Our singer got SOOOO peeved that night.
 
But then I see you have had issues even in a controlled setting, so I am just wondering if there isn't some sort of background service that kicks off - could some plugin possibly be hard-wired to check the web for some reason and somehow cause a problem?
 
I am really reaching for something for you - but I just don't know what else to point you at - sorry.

The event codes may relate to Windows looking for updates when there is no internet connectivity.
Google on e.g. event ID 202 devicesetup. How it relates to the reboot I dunno.

Myself I would certainly disable windows update. I always have it disabled on my DAW. I then will manually check when I have a chance and let it do it's thing. I disable anything that involves phoning home. Even if your offline those pesky automatic updates for all software are bad news for DAW. 
But somehow this seems like if you run Latency Mon then it should tell you what is causing DPCL issues. Make sure to keep it running while you test Sonar.

Is there any possible chance some scheduled task is running periodically?

To me it looks like that ... because it happens exactly one minute after starting playback ... like a driver stopped working and is restarted ... but which one ???
 
I suspect(ed) windows update or WiFi but deactivating either does not make a difference ...
 
Now, I googled those event messages listed above. They all originate from "Device Setup Manager - Windows 8 Service (Enables the detection, download and installation of device-related software. If this service is disabled, devices may be configured with outdated software, and may not work correctly.)"
 
If I deactivate this service, the event log messages go away - but the problem is still there at exactly the same point in time ... only now there is not a single message written to the event log near the critical time ... which leaves me even more clueless than before

I am not familiar with Win8.1 at all, but Win7 has those pesky "reminder" pop-ups that keep going like the energizer bunny once they start themselves.
 
I am sort of wondering if this is a flag internal to Windows to check for its "expected" monthly update, even though you are not online. Most Windows updates are non-invasive, and I have only had a couple over the years that I intentionally backed out of. More speculation here, but you definitely have one of the freakiest issues ever.
 
Based on your concerns with an update, an option is to create a system restore point manually, then put the computer online and let it update (manually run Windows Update). If anything goes amiss, you can 1) either restore manually or 2) uninstall the update from the updater utility. If you do need to back out of an update, you can also tell that updater to ignore it in the future.
 
If this truly is the updater itself, it is incredibly odd that more folks haven't seen it though.

Hello,
 
Per the Acer description: Shortened not your exact model but a W700 in general.
 
My focus is on the USB port.. Which is USB 3.  There are documented issues with USB 2 devices(drivers) accessing these ports . Maybe something else to consider. IHTH....
