A1-810 OTG (Keyboard or Mouse support)

DGP_Maluco

Hello community!

 

I have an Acer A1-810 with me and I wanted to connect it with an USB keyboard, I bought the OTG cable, the cable works I've tested it with my Nexus 7 2012, but the Acer tablet won't work with the keyboard connected trough OTG! Am I missing something? I read reviews saying it does inded support it. What can I do? It's on version 4.4.2 on Android (KitKat).

Thanks this is an urgent matter please help me!

I just got a suggestion to use the original USB OTG Acer cable, tested (not me) with KK and 830, worked.

How different can an otg cable be? It works with the Nexus it should work with everything

I have an A1-810 running KitKat & I use an eBay no-name OTG cable with it. I have previously used wireless USB keyboard/mouse combos with it satisfactorily.

 

I have just been trying it with a Dell multimedia keyboard that has an inbuilt USB hub, and a 5 button Dell optical mouse. The A1 works with either of these 2 components individually, but when the mouse is plugged into one of the keyboard USB ports neither of them work. I assume the power available from the A1 USB port is insufficient to run them both together.

I think so, power from OTG will not sufficient to handle two devices, will be interesting to try a powered USB hub connected to A1 and two devices.

Did you enable something or did you just plug it in and it works? I don't know why mine doesn't I just plug it in with the keyboard already and it just works on my Nexus

I just plugged it in & it works. (I have also used USB thumbdrives & card readers with this cable, with the powered mini hub mentioned below I have used hard disk drives on it, but it would not play with a DVD drive)

 

I have a OTG mini hub capable of accepting auxiliary power & will try it tonight. The A1 might still have a problem with the keyboard hub but you would expect the keyboard to work & for the mouse to at least light up.

Nothing no lights nothing, could the unit be defective? Is there more than a type of Acer A1-810 tablet? Should I activate the warranty on it?

IronFly

As far as i know, there's only one type of A1-810.

 

Wait until monday about the warranty, i sent this thread to an Acer tech (the one who suggested the Acer cables), let's see if something arise.

Thank you!

With the powered OTG mini hub the Dell keyboard & mouse both worked (with the mouse plugged into the keyboard hub). So there must be a fairly severe power limitaton on the A1 USB port which might be exceeded by some (e.g. illuminated) keyboards.

 

I also checked operation with USB hard drives, both FAT32 & NTFS. The A1-810 reads & writes to both.
