Default Charging and using usb hdd - possible?

Hi everybody

I'm just about to mount my carholder, and was wondering if it's possible somehow to charge my tab, and use an usb hdd at the same time?

I'll be using the tab for the children to watch movies, at it could be great to do it that way?

Thanks

As far as I know there's no way to do it, but there's always a modder who can prove me wrong... Stupid single proprietary connection.

Blame apple for the stupid single proprietary connection ... because that's who Samsung copied it from

The trick would be to find/DIY a powered USB hub that sends power upstream to the host device as well. You'll need a powered USB hub anyways for the HDD, power would come from the cigarette lighter.

It's risky, but maybe someone could take a non-powered USB hub and just inject more power into it. I've got an old USB hub that has two connectors on the host side. One for power+data and another one for just extra power ... what would happen if I hooked up the second power-only connector to something like the Samsung charger. Probably just fry the USB hub with too much current.

Oh, and if you want the Tab to charge with data you'll need a Pershoot Kernel ROM with Any USB Charge enabled on it ...
Galaxy Nexus (I9250)
- CM10.1 M3
Nexus 7
- CM10.1 M3
Nexus 4 (Hers)
- Stock
Galaxy Tab 10.1 (GT-P7510) (Hers)
- Stock
Nexus One (Babys)
- CM7.2

Feel free to feed my addiction to THANKS

You cannot fry anything as long as the voltage remains around 5V. The current drain (Amps) ist always limited by the device itself. You could hook up a power supply that is capable of 5V at 100A without danger to the devices.

However I doubt that any USB hub would send power upstream as this could indeed fry a device that is not made to accept current upstream like a normal PC for example. Also I think that the tab would not accept upstream current while in USB host mode since this mode normaly requires downstream current from the tab to the devices. So I don't think pershoots kernel would help.

Edit:
I just found the thread about building your own cables. Click

"USB Host with power" is what you are looking for. Although I doubt that there is an aftermarket solution for this. You will have to solder the required cable yourself most probably.
