Who here uses a USB hub to charge their t9193? I tried this on a Belkin USB hub without success (light indicator doesn't turn on). Is there a speciic way to make it charge through a USB hub or is mine just not compatible?
Does your HD2 charge from a PC USB port properly? A lot of times, USB hubs will need a 12v DC power source to create the 5v power required for USB devices. (Wall wart to the mini circular plug end found on laptops, etc) If your hub doesn't have that input, I'd find one that does. I bet that's your issue.
On a good powered usb hub maybe, but it will still
be less power than the wall charger and will not charge your battery as well.

My USB hub is powered by an AC adapter to the wall. I'm thinking it may be the voltage that doesn't work w/ the hd2 then..
So my USB Hub says
input 100 - 240V~0.8A 47-63Hz
output 5V 2.6A
That is probably spread over all the ports on the hub.
What else is plugged into the hub? Un-plug them and try to charge. Many hubs will say that and not come with the extra power supply. It is extra. Does yours have the power supply?
Yes, it has a physical power supply and when I tried it, nothing else was plugged in except the power supply to wall.
I'm on CM 10.2, so it could be a bug with that.
At work I have a usb 3.0 hub, which will charge devices at 1A, twice USB 2.0. But if you hook the tablet up to the hub the tablet will display that it's charging, but for some reason it really isn't. It displayed charging for an hour and lost 5% while screen off.
Go and enable USB Debugging and all the sudden the hub will light up and charge at 1A.
kinda dumb, but it works.
I want to create a USB powered 4 port hub setup for the shield. I'm curious as to the safety of having 2 separate USB power sources connected at once.
Basically it goes from shield to OTG Y cable powered by USB to a USB Y cable powered by another USB to 4 port hub.
Will this setup allow the hub to pull more than 2 amps assuming the USB Y power source can output?
The OTG Y cable is on amazon, "Apricorn USB power adapter Y cable AUSB-Y USB"

To be clear the Shield is my tablet
I suspect I know the answer to this, but I just wanted to get confirmation.
I was originally led to believe that the Galaxy S5's included USB 3.0 charging cable allows faster charging than a USB 2.0 cable. Upon thinking it over, the 3.0 cable should really only provide faster charging compared to USB 2.0, and only when plugged into a USB 3.0 computer port.
When using the same USB 3.0 cable via an AC wall adapter, the power output of the wall adapter should be the only thing that really determines the charging speed: Fast charging with a 2-amp wall adapter, slower charging with a 1-amp adapter; whether the cable is USB 2.0 or 3.0 should not matter.
Am I correct here?
The USB 3 cable provides only extra data lanes no extra charging speed. The AC charger will charge at 2amp and on PC you are likely to get not much better than 450mili Amp.
Does anyone able to use USB Hub while charging the phone? I have a Type C USB Hub with charging port. The connected USB devices became disconnected once I plug in the charger at the hub. They became connected again once I removed the charger from the hub. Is this an issue with the hub itself or does it have to with software on the phone? My Pocofone F1 are able to use the USB devices while still being charge so I don't think the hub is the problem. Can anyone confirm?
