How enable USB charging when PC switched off?

I would like to enable USB charging when the computer is switched off (I want to charge a DAC with battery).
The computer is a dual boot ASrock 3D Vison with Asrock App charger installed (in Windows)
I have already disabled S5 in Bios.
However if I shut down from Linux my DAC is not charging.
Some suggestions?

I have tried to use the little script in the link to find the address of my usb device. The result is this:
Bus 003 Device 003: ID 20b1:3008 XMOS Ltd
[FOUND] 3-1.1
So, if I understand right the directory is "/sys/bus/usb/devices/3-1.1/power/"
Inside this directory there is "level" with value "on" and autosuspend with value "2"
I don't have any idea how this (or other files) should be changed...if this is the right path...

Hello guys!! Please help me if someone knows what should I do. My iphone was working perfectly so far but a couple of days ago it stopped charging, its not charging neither with the a/c adapter and with the usb through my pc. It says device not recognized..

How to track Iphone when its switched off

HI SUMBODY STOLE MY iPHONE 4, AND ITS SWITCHED OFF NOW, CAN ANYBODY HELP ME HOW TO TRACK IT PLEASE

There is no way to track it if it is turned off. Be sure to report the theft to authorities, and change passwords for any accounts that may be accessible from the iPhone.

How do I stop my MacBook clearing the icons off the desktop when I switch off

How do I stop my MacBook clearing the icons off the desktop when I switch off the machine?

Hi Matt
After I create say a word document, file it on my desktop and then shut down my machine. The next time I open up the MacBook the file icon has been removed from the desktop. I can still retrieve the file in a folder labeled with the month I created it. But why has the OS removed it from the desktop and how can I stop it happening?
It happens to alias icons as well!

If your device has been jailbroken during the warranty, Apple will not service it.

When display switches off I can't get it back without forced restart

When display switches off due to low battery power & I can't get it back even when I plug in to the mains and have to force the PC to restart.
Is there a pref somewhere to disable this?

Hello
When the display goes off exactly? How much capacity has battery at this time? 5%? More?
Try to set this to higher level.
When you work with your notebook and battery level comes to low battery level and the alarm alert will be shown in task bar but you will be able to continue your work several minutes or to connect AC power supply.
I am afraid your notebook reaches critical battery level and then is maybe too late for any action.
Set Low battery level to 10% and when the notification is shown connect AC adapter immediately.
I presume the display must not be off at all.

When I switch off i5,all the pictures saved in camera roll is deleted

When I switched off my new i5 ,all the pictures saved in camera roll is deleted.How can I fix this problem?

Nevermind, everyone! I fixed it myself! Anyone who has or ever gets this problem, do understand that it isnt easy to fix it, but it's worth it. All you have to do is go to the photo, and tap "Edit". Then tap "Crop", and just a little bit will do the trick. Then, tap "Save". It will probably come up with a white background. Unfortunately, you must do each picture one by one. If you really want to, you can go back to any picture you've cropped, tap "Edit", then tap "Revert to Original". This will change the photo back to it's original size.

How to instal software when the mobile is not swtching on

You can't do anything on a Series 40 phone such as the 5610 XM other than a revert to factory default settings, which probably won't solve the problem for you.
You need to take the phone to a Nokia Care Point before the warranty expires and get them to fix the phone.

No texts come through when phone switched off

When iPhone 4 switched off and someone sends a text message through why don't I receive it when phone switched back on? Is it my provider? My settings? Or phone? Any suggestions would be greatly appreciated.

SMS is a carrier function. It's going to depend a lot on how long you have the phone switched off. Different carriers hold messages for different amounts of time before they are deleted as undeliverable. iMessages are a data function unless they can't be delivered, which case, depending on settings, the sending phone will try to send them as SMS messages.
If this is an issue for you, I'd recommend considering putting the phone on mute rather than turning it off. Of course, if you are, for some reason, required to turn it completely off, that won't help. The only places I've been required to turn my phone off in the past year were on airplanes and while being detained at the border.

Is it normal that every time when I switch off my Iphone 5s and then I turn it on again I have to insert my pin code?

My Iphone will only charge when it is off???

I just got my iphone 4 about around june of this year and ever since two or three days ago I plugged my phone in because it was dead and it would not charge but when i got it home to charge it it charged all the way and not today its doing the same thing it will only charge when it is off and then as soon as the cord powers it back on it will stop charging and say 10 pecent batt left... I bought a new cord and it still does not charge my phone idk what to do this is really annoying i also tried my charger in another iphone 4 and it charged that phone so its not the cable it has to be the phone but the phone is brand new and never has been damaged i am going to verizon to hopefully get a new phone but in the mean time looking for any suggestions or tips or maybe somene is having the same problem too

Also when i have the charger plugged in after the phone dies it will show the charging batt symbol but as soon as it powers back on it says 10% battery life again and then when i power it off WITH THE CHARGER STILL CONNECTED the phone will not show the charging battery symbol again whihc means i have to take the charger out and put it back on and it dose it all over again charges with off but as soon as it powers on automatically it stops charging

I have ipod 4 touch. 3yrs old. when i plug in it isnt charging. it gets switched off after the charge gets over. then it charges and again switches on. dont know how to solve this problem.. please help

IPod 4 touch. 3yrs old. Not charging when plugged in. But charges when the battery gets drained. when battery gets over I keep it for charging. It switches on and doesn't charge.. Plz help!!;;

Not Charge
- See:
iPod touch: Hardware troubleshooting
iPhone and iPod touch: Charging the battery
- Try another cable. The cable for 5G iPod (lightning connector) seems to be more prone to failure than the older cable.
- Try another charging source
- Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.
- Make an appointment at the Genius Bar of an Apple store.
