Post subject:  A43 charging & USB Host at the same time?

Hi,

I just picked up an A43 off ebay. The problem is that I can't figure out a way to charge and use an external USB drive at the same time?

It seems that I can only do one or the other, not both at the sametime. Is this correct or is there a way to get them both working either on the stock Android or Urukdroid?

I have an OTG cable hooked up to a powered USB hub where I am trying to connect both the power cord & the USB drive.

Thanks!

You'll notice that on connecting to a USB host such as a PC the dialogue offers the choices "Mount" or "Charge Only". There's nothing anywhere to suggest that the battery isn't charged when the A43 is mounted as a storage device. You can confirm this for yourself while the device is connected and file system mounted: Settings>About Device>Status - the Battery Status shows "Charging (USB)" and if you check again 5 minutes later you'll notice the battery level will have changed. I assume it might stay the same or even decrease if you are constantly reading/writing to the file system but check while idle and you can see the battery definitely gains a charge.

Yes, you are right. You can't charge the A43 and use an external USB drive at the same time. You cannot use the OTG host cable to charge the A43, and the OTG cable need to be connected directly to the A43 to make it as a host and use the external drive. So you can only do one or the other.

(1) external drive ---> USB hub ---> OTG cable ----> A43, then it will read the external drive but won't charge the A43.

(2) external drive ---> OTG cable ----> USB hub ----> A43, then it will charge the A43 but it won't read the external drive.

It is a physical limitation, so changing your OS will not help.

Oh yeah..otg...racky is right.

Sorry my brain was off and I was thinking of plain USB connection to a host.

Thanks so much for the responses! That's too bad, but at least the A43 has a good battery life.

After a few days, I've really been enjoying it with the Urukdroid firmware!
