Just a FYI,
My anroid device will not charge when plugged in to my netrunning (rolling).
What happens is KDE offers what do do and I can open the device to view files in dolphin ok.
While I have it open it will charge for a short time and will then stop charging, if I open another folder in dolphin or look at a picture etc it starts charging again.
if the device is not mounted at all the phone will not charge at all.
The phone charges fine with the wall charger, just not when plugged into netrunning KDE (rolling arch based)
That is caused by USB power management kicking in.
Netrunner Rolling (Manjaro) uses TLP to control power management:
Open up the TLP config file:
kdesu kate /etc/default/tlp
Search for this section, then un-comment this line and edit it using your phones ID:
If your unsure of your phones ID then use this command to find it:
lsusb
Alternatively, if you don’t wish for your USB ports to suspend at all, just change the line in the section above that one to a 0 instead of a 1 like this:
# Set to 0 to disable/1 to enable usb autosuspend feature
USB_AUTOSUSPEND=0
