USB charging problems
Hi..
I've been having an ongoing problem trying to charge various devices (smartphones, tablets etc) via USB. The devices seem to connect to Windows without a problem and I'm able to browse the file system of the device in order to move/copy files between them and Windows but charging seems to get interrupted every so often and a few seconds later, charging starts again. During the time the charging stops, I'm still able to browse the file system so the devices are staying connected, it's just charging that is affected.
I've tried uninstalling, reinstalling devices and USB controllers but that hasn't helped.
I've also tested the same cables when connected to a wall charger and didn't experience any problems.
I've used the same cables to charge the same devices from a different computer and again, that went fine.
Things seem to be pointing to a hardware error of which there are no clues in the event log or device manager. However, as a test, I tried charging on XP which runs as a dual boot option on the computer and that was fine too so it seems to be something specific to this installation of Windows 7 x64 Ultimate SP1.
I've read an article which suggests to delete upper and lower filters registry values from the USB class string. Both filters were present but empty so I backed up the key and deleted them but that hasn't made any difference.
Kinda struggling for the next things to try so if anyone suggest anything that would be cool.
Thank you :)
