I've got a cheap old laptop and a cheap new Android phone and a cheap unpowered USB 2.0 hub I just bought.
A few minutes ago I noticed that connecting the phone to the laptop via the hub, while recognized by both devices as charging, does not actually charge the phone battery. In fact the charge was slowly going down as I was using it. (Yes the laptop is connected to AC.)
Before I got the hub I regularly charged the phone from the laptop directly and it was fine.
I bought the hub since my laptop's keyboard is going bad so one USB port is taken up by the cheap USB keyboard. But it worked great with the keyboard, a mouse, and the phone connected to transfer files, all at once.
Is it normal behaviour that connected devices would work but charging wouldn't? Or is this just a sign that the hub is a cheapie?
I'm just asking out of interest really. The situation is not dire (-:
