I have tried using one I have with Raspberry Pi but it didn't recognize 2 WD drives connected to it.
Yes, but you may need a powered hub for HDDs
Is there a difference between different hubs? Shield TV should have enough power for powered HDs. Raspberry Pi did at least.

I'd prefer to use a powered USB hub instead of drawing more power from the Shield.

Hi, im wondering if i can use a USB hub with my acer so i can have a keyboard and mouse hooked up before i buy one.
Yes it does.

Sweet! Thanks for the info
Yes but limited to power Requirements
As stated above it will Support a hub ..
But with limitations on devices.. you will not be able to say use a full size usb hard drive while connected to a keyboard and mouse at the same time. I belive this will be to much power . look at the amps and the devices are pulling and compare them with with the Hub says its needs are.. But this is common on any usb hub. they make some that you can use with or without power cord.. I have one that works will i think its a cheaper belkin brand..... very tiny and have 4 ports..

I have yet to see a "full size" hdd that doesn't have it's own power supply. Now an external portable laptop hdd is a different story

You are correct because they require 12 v.. I use a 1.2 tb laptop drive in a enclosure on mine... it works without power but when powered its much faster.guess there is some type of throttle software.. mine has sata connector . that i also use on my laptop on the esata port .. there its awesome fast.. I have linux windows 8 and a diag version of dos installed on with a nice multi boot loader of course..
For those into games.. my sons Saitek x45 flight controller works on the a500. but MUST Be connected to a usb Powered hub . not sure what he plays with it other then the racing game.. from gameloft. So glad he is off to school now so i get my tablet to myself again...
Hello, I want to know how many USB-Devices you can use, assuming you use a normal USB-OTG cable and a cheap USB hub (without external power supply). How many devices can Android theoretically recognize? Is it possible to use a keyboard, mouse and USB stick/HDD? Would be cool if someone could try this....
Thanks in advance!

Android can recognize as many devices as there are USB hub ports, check out this video (I know it's for the Galaxy S3 but the idea is the same) specifically 2:50 seconds on using a USB hub with mouse, keyboard, and other accessories.

Thanks, but I think the hub used in the video has an external power supply. At 3:50 you can see the black round cable...

It should work the same with a non powered USB except that power will be drawn from the tablets battery power instead of an external power supply.

I tried to use multiple usb flash drives but they were not compatible with the aosp roms otg storage implementations. It recognized the first and after adding the second it didnt recognize it, but the first onewas still tdhere
I think in this case its simply not implemented
I will try flash drive + mouse/keyboard and give feedback when i have time

I tried for a couple of days to tweak the implementation in my kernel mod so that multiple usb drives could be mounted, i took pointers from my s3, but it seems samsung have further mods, probably to vold in their own brand devices and i couldnt for the life of me get it to recognise more than one device on the n10.

I think a powered hub is the way to go if you're using multiple devices as I'm sure there's a limit as to how much power the USB port can supply to your devices. You may find that several flash drives work fine together with a powered hub and I would try to get one with a 5v 2a adaptor if possible to give you flexibility to plug virtually anything in you wish simultaneously

Without a powered hub the deciding factor for how many devices you can use is going to be how much power each device draws... And that will vary from device to device.
I, personally, have had a keyboard, wireless mouse, flash drive and Xbox controller all connected at the same time with an unpowered hub.
Yeah, multiple flash drives and especially external USB spinners tend to draw a lot more power. Input devices (keyboards, mice, joypads) use very little power but a combination of several may be enough to give you intermittent operation and a few issues.
Usually when people start connecting keyboards and suchlike, they're going to be at a desk so should have access to a wall socket anyway; powered hubs tend to make multiple devices work better as it's a stable power supply available.

do you think the n10 provides less poser on its usb bus than a pc or laptop? i think its able to provide the same power as my pc and 3 usb sticks + wireless keyboard/mouse work perfectly with a non powered hub...
btw. i just tried the hub with 1 flash + mouse+ keyboard, works perfectly (aosp rom 2nd dec version i think)

I'm pretty certain that it does provide less; I have a 2.5" WD Passport HDD that is bus powered. My XOOM used to power it, my PC and laptops power it, but my Nexus 10 doesn't. The N10 certainly isn't pushing 500mA in host mode cause the drive can't even spin up on the power its receiving. It's a real shame cause I had hoped to power the HDD directly.
What I need now is a nice small powered hub that I can power from an emergency phone charger battery, like my Mili Power brick.

Here's my simple little setup. Consists of two Logitech F310 controllers, Seagate 2TB USB 3.0 had drive, Pluggable Peripherals 7 port hub and of course the official controller. Also has a keyboard and mouse dongle plugged in. I'd love to see others. Post em! (BTW, forgive the white extension cable, it is actually connected to the hard drive as I am in the process of backing it up)

6months old photo, but still using the min combo BT keyboard, charge the AAA batteries on the TV usb with the USB hub under it.
And I keep the mojo on it's side.. i think it looks cool and lets the heat rise.
I'll take more pics when my other controller comes

I wont recommend the mini nor the micro (button keys instead of real keys unless it a remote maybe), it's okay for quick surfing/emailing but not for chat etc.. great for my travel bag.. but I would use it more if was more fullsize... I need to replace my old wired keyboard mouse.. so i'll be looking for a fullsize BT combo.
From top left:
AverMedia Capture HD II C285, MOJO 4way USB hub, 32GB roms, cheap twin PS clone controllers on one USB, Behringer headset for late night gaming sessions.
My old USB keyboard and MS laser mouse, 7inch Hyundai T7s, Travel clip with my tablet mod.
MOJO CTRLR, retail CTRLR, Shintaro Mini Bluetooth Keyboard.
And under the TV I have a 4way USB hub powered by the TV's USB port.
Attached are two USB AA/AAA battery chargers and a retractable USB cable for the mini combo keyboard to charge.
Not that much really
Hi! So I was thinking about buying a raspberry pi. But on their website when you go to buy a raspberry pi there are some "must have" accessories. But what if I don't buy them? Can I do anything with only a raspberry pi and a pc or I need additional stuff?
You need a microSDcard to put the OS on and you need a power supply (5V 2,5A). Depending on what usage you probaly need a screen and a HDMIcable and maybe a mouse and a keyboard aswell.

Ok nice thanks for the info! But can't I connect the Raspberry Pi to the PC via USB? And you know power it that way?

Havent tried that myself, but i dont think it will work, USB only outputs 0,5A and Pi wants 2-3A.

Ok I guess I will get a power supply with micro USB then. I have some of those lying around from phones. But I plan on getting the Raspberry Pi zero so I won't need more than 1 2 amps I think. Though I read the hardware guide on their website and I realised something. The Raspberry Pi is a computer itself so when you want to program it on your PC I guess you connect everything to it and it runs as your main computer instead of just plugging it in your PC via USB and using it like an accessory. Is that correct? Because if that's truly the case then I will need to spend some more money than I initially planned.

For a Pi Zero a phonecharger will do and, yes, the Pi is a computer that can run diff OS like https://dietpi.com/

Ok thanks! I will probably order it now and get it. But before that just want to ask the Pi Zero is setup the smlame way as the Pi 3 right? I mean you plug mouse keyboard and monitor in it and work it that way. Also will it work if I plug in my monitor through a DVI to HDMI adapter?Also if I have to plug in the keyboard and mouse into it it has micro USB ports so I guess I will need two USB OTG cables that they sell on their website in order to plug in a normal USB right?

For some reason Im thinking youre still waiting for an answer... The best advice anyone here will tell you is that there's much better forums out there that are specifically just for the RPis', as in this degic
Has anyone successfully used a Powered USB Hub with their Android Head Unit? I tried hooking up a TP-Link 7 port USB3 hub to my Dasaita head unit, but the hub is not recognised, and nor are any of the devices plugged into it. I would really like to hook up a powered hub for fast phone charging, as well as doing other normal hub stuff, like reading thumb drives etc. I also tried hooking up the TP-Link hub to my phone via OTG, but it doesn't recognise it either, so I'm guessing it's an Android thing.
Any ideas/suggestions/advice very much appreciated.
If I recall correctly, the unit doesn’t produce enough voltage to power a hub. You need one that’s externally powered and can be plugged in.

Yes, that's exactly what I am after, ie a Powered USB Hub.
I have a really cheap Chinese 4-port active USB hub from AliExpress connected to all my devices. It has 4 switches to activate/deactivate each single USB connector.
Powered by a 12V to 5V / 2 amp power adapter. Works like a charm.
