Your topic is about charging. So is it charging or not?
If you want to discuss the USB tether and driver issue, then I will wait for you to tell me more about the make/model PC and exactly which AQ4501 USB driver you installed.
There is clumsy problem happening...
I charge my mobile thru pc USB it gets charged till battery full but after full it pop up on windows that " device not recognised ".
I did one thing, I use my mobile so to reduce battery bar from full to lower and then connect it repeats same problem ie " device not recognised " when battery finishes full charged but before reaching full it is ok no pop up comes that time.
I find the same problem when I do USB tether for net access ie I can access internet untill battery reaches full and after full it displays "device not recognised" and internet got disconnected.
pls note that I can transfer data to and from pc and mobile as that would not have been possible if data port pin of pc or mobile damaged.
I uninstall my driver and reinstall which got auto installation after mobile got connected to pc but problem persist.
I did not try my pc USB port with other mobile to find whether same thing to happen but could you tell what could be train.
