My new Windows 8 machine keeps disconnecting from my Roland Quad Capture when it sleeps. So I need to unplug the USB from the back of it and re-connect to initiate the USB to be recognized. It's annoying, especially when I have turned on Sonar and have to turn it back off again, to pick up the device. I have set the power management to 'not allow computer to turn off to save power'.
 
Is there a away to stop this turning off, or to re-set it without pulling the cable

There is power save setting for the USB ports also. You need to put it to "do not allow this device to fall asleep". It was not those exact words but close.

Sorry, that's what I meant by this
 
"I have set the power management to 'not allow computer to turn off to save power'."
 
This is on the USB ports on Device Manager

Ok. Perhaps you could put power saving off from the BIOS also. Just be careful to not make accidentally other changes in the BIOS.

I always have my Sonar computers set to NEVER allow sleep or hibernate and also I turn off USB Selective Suspension of devices (that one is in Advanced Options for Power Management).
 
So, all my USB devices are on all the time, and the computer always runs at maximum processor state, and never sleeps or turns anything off, and all is well.
 
Give that a shot, please, and post back.

Try the Control Panel power settings rather than Device Manager.
 

I have a Duo Capture. When it hangs up, I find that flipping its (hardware) switch to another sample rate, waiting a second or two for the software to catch up, and then flipping back to the original rate is enough to reawaken it. Sorry, I cannot remember whether Quad Capture has the same hardware switch, so this information may or may not be useful!

I'm really intimidated by BIOS changes, I basically have no clue on how to use and every attempt in the past has left me scratching me head.  IOt's been a while since I started this thread. I think the idea of having to tackle BIOS scared me off.

I stay in a hotel and when I leave the room the power cuts out. For heat reason I'd rather not leave a laptop on at all times, and I sleep in the same room.
 
I have those setting in power management for the USB Selective Suspend to be disabled both on battery and power.
 
Thanks for the Screen prints BobF, sorry for not thanking you effort earlier.

 It's not hanging in use, just when it sleeps, and it turns back on after I open. At this point SONAR states it was disconnected and there is no way to re-connect without shutting Sonar. It's this part that bothers me, it's a faff.
 
I never had this issue in Window 7 on my last laptop, so maybe it is just a BIOS issue. I updateed the Quads Software a few days back and this issues still occurs.

Braved it and looked in Bios Settings. The only one I could see was;
USB Charging             <Enabled>
 
Enabled allows Mobile item to charge in sleep mode, so it seem if anything it would helping this issue.

Windows is not elegant about hibernating and coming back out of hibernation. I do not know of any way around this other than to never have the computer sleep/hibernate. If you have heating issues from leaving it on, you really only have the option of cycling power to the machine deliberately or doing what you are doing now.
