[HOW TO] - Connect Multiple USB Devices At Once - Xoom Accessories

PLEASE NOTE: This is for those that are currently unaware such things are even possible. Many of you already realize this following is possible. Great! Now, go help the community by spreading that knowledge to the less enlightened.
You'll need the following accessories:
* Motorola Camera Connection Kit (or other compatible OTG cable)
* Targus 4 Port Retractable USB Hub (or other compatible 4-Port Hub)
1) Plug the Motorola cable into the XOOM's MicroUSB port.
2) Plug the USB Hub into the Female end / port of the Motorola cable.
3) Plug your devices into the USB Hub.
Enjoy!
This requires the 3.1 software update but does not require unlocking, rooting or flashing. It should work with all stock XOOMs out of the box after being updated to v3.1
This has allowed me to plug in two wireless receivers for an existing keyboard and mouse I already had as well as my digital camera and android phone. However, DO take care to avoid connecting devices that require too much power ! Doing so could disrupt the operation of all connected devices at the very least!

Simple
I believe that any USB Hub would work, Just depends on the power that the devices plugged into the hub needed and the addition of an AC/DC cord. My USB OTG adapter is expected in the mail so I'll test it when it gets here.

[Q] Desire HD USB OTG Host cable

Hi,
I've been wanting to hook up my desire hd to usb hosting and have not been able to find a cable for it.
I was wondering would it be ok if i connected a micro usb (male) to usb b (printer version) (female) adapter
to a,
standard printer cable with usb female at the end?
This would result in one end being a micro usb male and the other end a female usb
I look forward to your answers
Thanks alot for reading
That probably wont work.
I in fact saw an article yesterday, but can't recall the link. (Will look now).
IIRC, you need to modify the USB cable somewhat to get the DHD's USB port to detect an OTG connection.
Edit:
Here we go: http://gigaom.com/mobile/how-to-add-a-usb-keyboard-to-an-android-phone/
I think if the software supports usb host mode, with a 'micro usb type a' to 'usb type b' cable you can connect to a usb device. That is if the DHD is equiped with 'micro usb type ab' receptacle.
oh wow, ok thanks ever so much!!,
however, i just need to confirm what three cables you need so i can go out and buy them, i need:
Car charging cable (which one is this?)
Micro-usb cable (is this with the microusb male on one end and a standard usb male on the other end?)
USB extender cable (is this with one usb male and usb female on the other end?)
thanks

I have no idea really, but if you are successful, let us know
I'm just having trouble understanding what cables are needed.
On the website you gave me, it says i need:
a car charging cable, a micro USB cable and a USB extender cable.
Is this effectively two micro usb cables and a USB extender cable?
or does one HAVE to come from a car charging kit?
please help!!
thanks

Nice find! I did see the mini one only
Gonna order and try it out. No great financial loss if it does not work.
Obviously we will need a USB Host module for the kernel if not already present. Will check tonite.
i've finally made my host cable!!!
i now need micro-usb dongle host module. Is this where you have to get hold of a car charger and get the end of it and unsolder bits?
The USB Host module is software. It is loaded by the Linux kernel.
ok well i need to get that too.
Also, whats the bit with the car charging cable? what that for?
I'd be really interested in this as well. Would be awesome if i could just connect a usb drive or my camera to my phone to copy data.
So does anyone know if a host driver is available for the desire hd.
I really have no idea how it would work, but it should, as loads of tablets are able to use 3G-Sticks to connect.
Today I recieve my USB Host adapter cable for the DHD.
When I plug it into the DHD and connect a USB Hub the car panle ("Auto Bedienfeld") starts.
Connecting a USB Keyboard to the USB Hub doesn't show any impact. But this is what I have expected. Next I try to integrate the patch from sonic74 to a kernel for the DHD.
http://sven.killig.de/android/N1/2.2/usb_host/
At the moment I use Android Revolution HD 2.0.9
Any progress?
I really like the USB host future on my Desire HD,
I want to connect my USB Drive to my DHD if this is possible? So i have 16GB More storage if needed ;D
I've ordered the converter thing from dealextreme, someone that could make a flashable zip to enable usb host functions?
Was also quite interested on this.
My wish is to connect my dSLR to the phone, and move all jpgs/nefs from there to a internal card. Or copy, and use the device for better visualisation.
As the camera has its internal battery, power shouldn't be a issue. It would be awesome
I am still working on this.
At the moment it is working for a short time, but then there a same errores.
This meens it should be possible, but same more research must be done.
My Kernel is based on the BUZZ 1.3.7 Kernel, and following patches:

[Q] Micro USB to USB Converter, mouse and keyboard simultaneously

Is it possible using this kind of converter to connect simultaneously a mouse and a keyboard together to the phone ? (for example using a wireless set mouse/keyboard or a usb splitter).
Can the phone provide the power to work on both devices ?
Maybe if it was possible to charge the phone somehow using the same cable ?

I would be interested in this too. I saw EVO 4G used as a desktop computer - http://forum.xda-developers.com/showthread.php?t=1038840 but he used bluetooth mouse and keyboard and the only thing connected to its micro usb port was hdmi cable. I would rather use some kind of usb hub in order to connect these 3 devices to the micro usb port in the phone and even charge it all at once. If anyone knows if it is possible please share your knowledge
BT
Yes, you are right about Bluetooth. I believe it's the best solution (but more expensive) because when connecting the hdmi adaptor no other ports remain for other usb devices. Also hmdi adaptor charges the phone (for example BizLink MHL to HDMI TV-Out Adapter)
thanks
You might be able to run both USB mouse & keyboard; try using a keyboard that has a USB port or two on it, then plug the mouse into the keyboard's USB. Power may be a problem; the SGS2's USB connector isn't going to provide anywhere near the 500 mA in the USB 2.0 spec.
Of course, if you're using the USB, you can't use the MHL/HDMI, and vice versa -- the connector modes are mutually exclusive. If you have to have HDMI output, you should be able to use a BT keyboard and/or mouse.

[Q] USB Hosting

Hi All,
I have rooted my SGH-T989 and have flashed Zedomax's kernel to allow the USB Hosting functionality on my phone. This has worked great and I can now use a mouse and keyboard via a USB Splitter into a single OTG cable plugged into my phone.
The Setup:
Samsung Galaxy S2 SGH-T989 (Rooted)
Zedomax-T989-Kernel-v0.1.zip from
w w w .theandroidsoul.com/connect-usb-flash-drives-mouse-keyboard-etc-to-t-mobile-galaxy-s2-t-989/"
OTG cable
w w w .amazon.com/Micro-USB-Host-Cable-accommodating/dp/B005GGBYJ4
Belkin USB Hub [/URL] from

Normal USB mouse and keyboard
KVM Used to switch mouse and keyboard from Desktop to USB Hub for SGH-T989
The Problem:
If I use the mini to USB cable supplied with the Belkin USB Hub to the OTG cable the mouse and keyboard are recognized and usable. However, if I don't use the OTG cable it will NOT recognize the mouse and keyboard.
That is not my issue, I'm ok using the OTG cable, but it leaves me with a Female USB placeholder. Therefore, I have to connect it to the USB Hub. Obviously, the Mini to USB A cable worked for hosting, but it does not supply power to the phone even though the USB Hub is plugged in and powered.
My initial thoughts were that the USB Hub does not supply power out the side mini USB so I bought a 1.0 USB A to A , 2.0 USB A to A, 3.0 USB A to A, Gender Changer for OTG cable. and no matter what cable I plug into the front USB slots on my USB Splitter, I get NO POWER and NO HOSTING. Nothing seems to flow through to the phone other then the one Mini to USB with OTG, but leaves me powerless.
I have also bought the docking station, which I later found out that even with the OTG cable will not push the hosting through to the phone and had to return it in favor of a more generic stand to hold my phone landscape.
I am out of ideas as to what to try next to get power and hostability to my phone. Please help!
Thanks,
Sam
Odds the USB hub powered? I remember that the first OTG kernel that came out said the hub had to be powered to use a mouse or keyboard.
The hdmi cable has to be plugged to the phone charger as wellfor it to work
Sent from my SGH-T959 using xda premium
Yes it is powered, I have also tried unplugging it to remove power. However, the OTG cable will accept the KVM mouse and keyboard plugged directly into the OTG cable itself.
The one thing I'm not certain on is whether or not the mini to USB out of the side of the USB Hub is supplying power or not. However, that is the ONLY spot that is working for pushing the KVM Mouse and Keyboard through to the phone. Without just plugging KVM directly into the OTG cable.
The KVM is plugged into the USB Hub and the Mini is plugged into the side by the power and then plugged into the OTG. This setup works for hosting, but all the variations of plugging into the normal front facing USB spots of the hub have failed to do anything but bring in power. However, I have NEVER successfully brought power through the OTG cable, so I'm not even sure it can support power at this point.
Sam
the only devices that does not need additional power are USB keys / flash disk storage and the likes
everything else you need to plug it into a powered USB hub, and have the hub connect to the USB OTG cable
and you do not need any special Kernel for USB OTG to work on this phone
USB OTG works from factory stock ROM (i just tried it to verify )
Hi Allgamer,
Thank you for your insight. However, I did try the OTG cable before getting the special kernel and it DID NOT function. Once I downloaded Kedomax's kernel I was successful. This appears to be a feature they removed from T-Mobiles version.
As for the Power issue. If you guys would be so kind as to reread my initial blog and reply before posting power things to try as I have listed that I have tried powered and unpowered and plugged directly and indirectly and through a usb hub and without, all variations and cables to plug and play have been exhausted.
I'm looking for a more advance analysis that may help provide a solution to my current problem. I'm not sure if the OTG cable can allow power to pass through to the phone or not. I have yet to see that work. I'm also thinking I cannot host without the OTG which seems as though it would leave me in an infinite loop.
Here are more along the line of questions that I'm hoping someone can provide insight to as I have no way of answering these questions myself without an extended work bench and wider test result devices.
1.
Can anyone confirm that the OTG cable can in fact provide power to the phone as well when plugged into a USB Source such as a HUB that is providing power out the USB ports to the OTG cable itself.
2.
Can anyone confirm that the OTG Cable can still support hosting capabilities if power is being sent up the cable or does this disable it in some way.
Thanks again for your responses, no disrespect intended by my redirection of the thought process here.

MHL with USB OTG?

Has anyone found a MHL cable that also includes a USB OTG port? Samsung reportedly changed from a 5-pin configuration to an 11-pin configuration to allow MHL with USB Host mode simultaneously. Perhaps for a future Desktop Mode?
Has anyone been able to find one of these cables?
Just wanted to update, I believe I found the type of connector that I was looking for, but it is missing HDMI and it is sold out. This essentially could give you PC type connectivity on the S3.
http://www.mobilefun.com/35462-mobile-fun-connection-kit-for-samsung-galaxy-s3.htm
I think we still have a bit of a wait. What you found is essentially a USB OTG hub with some card readers built in. I seriously doubt this will pass through the pins for HDMI to work out of the usb port. We'll see something when this phone finally launches everywhere. It's not even out in the US officially yet
EDIT: Sorry, didn't see the article in the link in the OP. Man.. I might have to get me a GS3 now. I'm quite satisfied with the reasoning for a pin change. =)
Samsung sells 11 pin MHL adapters and USB female to Micro USB male adapters on their accessories page, but I'm not sure if you could piggy back the USB input into the charging port of the MHL cable. I don't see any all in one cables on their site, and the desktop dock is just micro usb/audio. I tried.. =(
Here's what I was looking at.
Old and mostly unrelated. See edit.
I happened to buy what looks exactly like that adapter today earlier at Micro Center. Now, I do have a Galaxy Nexus, but the USB OTG works great with keyboards/usb/mice/hubs; however, I cannot get it to simultaneously work with my MHL adapter. I understand the GS3 has a different pin layout though for MHL - my phone works with my MHL adapter correctly, but I didn't think it would have any change on the USB OTG. I'll most likely be breaking these apart and start tinkering. My goal is to show people how much of a full desktop-like experience I can provide from my phone, since so many people somehow think a GNex or GS3 are inferior to tablets, just because they're smaller... lol
Good luck finding information out on some kind of MHL/USB OTG setup. I'm just trying to provide any information I can from how my situation works with MHL/OTG, since I'm currently on the quest to achieve this myself.

I'm not really sure why people think they NEED MHL and USB OTG simultaneously to get a "desktop-like experience". You can already accomplish this with just a plain MHL cable and a bluetooth keyboard and mouse as was demonstrated in the Connectivity Demo video on youtube.
Edit: Actually I just remembered about portable hard drives. If you want to hook up a mouse, keyboard AND hard drive I wonder if you can plug all three into a powered USB hub connected to a bluetooth dongle. Hmm...
I'm looking for a dock with USB OTG, charging and MHL. Maybe some day.
I believe this is already capable. Everything I say here is purely speculative, but what I see is that Samsung moved to a 11-pin connector for MHL and the standard 5-pin is no longer functioning. To call it MHL, they probably have to use the same standards for data encoding... but they simply "moved" the pins.
I put "moved" in quotes because of the way in which a standard 4 pin USB cable works (or 5 pin for our case)... you have a +5V, Ground, Data + and Data - (one data to phone, one data from phone, carrying ALL data). Since our phones still sync via 5-pin cables, this means the 5 pins are still "hot" for data like all other phones. I am presuming, that for the 11-pin connector, Samsung simply added a few more data+ and data- connectors (much like having two or three USB ports on a normal computer) but consolidated the ground/5V reference. I could be wrong, but it would make sense.
Lets call the stock 5 pin data connectors (2 wires) USB1. This is where MHL is conventionally sent through and all sycing can be completed through, 5 pin cable or 11 pin cable. If samsung added two additional USB ports to the single connector, lets say MHL is now over USB2 (wires inaccessible to 5 pin connectors). This frees up bandwidth and COM ports on USB1 and USB3 to use for accessories like a USB hard drive and keyboard/mouse. On a 5 pin connector, however, only USB1 is accessible. The Samsung 11pin to 5pin MHL adapter simply moves the data+/- from USB2 to USB1 (standard 5 pin location), so with the adapter you are syncing/exporting video over USB2 on the phone with a standard 5pin cable.
My thinking is such: If you plug in the OEM 11pin MHL adapter, it will also have access to the standard 5pin USB1 connection. Since USB2 is used for MHL, you can then plug any OTG device into the micro USB connector on the MHL adapter to make use of it. The only problem here is power (or lack thereof). By plugging in a USB hub with a discrete power source, plugging this into the MHL adapter, and plugging in the USB device of choice into the HUB, you *SHOULD* be able to get simultaneous data and HDMI. This assumes they put the standard 5 pins to the connector on the side of the MHL adapter and only wired the HDMI to the USB2 area.
Alternatively, you *SHOULD* be able to plug the micro USB cable from the MHL adapter into a computer, and simultaneously be able to sync files while outputting HDMI video. It sort of just comes down to being able to provide power to the MHL adapter on the +5V pin while using the data pins to access the phone. As soon as I have my MHL I'll figure it out, but that could be a bit. If anybody has access to a pinout from a Samsung 11 pin micro USB that would be helpful too.
Again, just dreaming here. I don't know anything about this, but if I was the engineer at Samsung I would choose this over analog outputs like Apple used for their giant connector.

for me at least i already have several keyboards and mice ... none are bluetooth.
I'm looking for the cheapest option available.
I'm just hoping someone releases a cable with 4 plugs:
Male MHL - To Phone Obviously
Female MicroUSB: To plug in charger
Female HDMI - To Display
Female USB - To USB Device
That's all I want... should cost less than $2 to make, just sell it for $20 and I'd be happy.

hi v8bait, are you able to get data thru the micro usb port at the side of the 11-pin mhl adapter? i was thinking of using the motorola lapdock with my s3 thru the mhl adaptor (other then a micro hdmi male connector, the lapdock also has a micro usb male connector that apparently send out power as well as push keyboard/trackpad data upstream) - if it works, we can have an inexpensive "clambook"
Just to recap,
Will this we possible:
Official MHL adapter -> hdmi to monitor.

>OTG cable> Powered USB hub> USB keyboard & mouse.
In other words, the PC Experience with a keyboard and mouse.
Dont really want to spend the money to buy a Bluetooth keyboard and mouse when the USB ones can work just fine (theoretically).

I am also very interested in this exact thing. Using USB devices (multiple ones, e.g. plugging a powered USB hub into S III and then plugging them in) but also putting out S III video to HDMI.
However the other workaround is using AllShare Cast. In fact that is the route I'll likely go, because of the other unique advantages of AllShare Cast (i.e. using it for presentations to screens, etc.)
So: has anyone plugged a powered USB hub into S III and used multiple devices? Such as a keyboard and mouse?
I also want to use this S III more as a computer. the other perfect thing I wish I could buy would be a keyboard case, like the one available for iphone, so I can prop the S III up on a kickstand and use a real mini-QWERTY physical keyboard.

We're in the same boat; i want to use the s3 like a mini computer too. I think it'd be great for business travel, when i dont really need a laptop during the day but want something when i'm back in hotel room. I'd much rather use hotel TV instead of a laptop because that's what i am used to at home... pc hooked to TV.
I've been planning to use the allshare cast dongle too, but they dont seem to be available yet. I was thinking HDMI out with the allshare.. charging with the wireless charging kit and then keyboard and mouse with USB OTG. My logitech unifying receiver for keyboard/mouse works perfectly i just need the wireless charging and allshare dongle to be released.
For what it's worth I tried a powered USB hub and could not get it to work with the s3.

Wait so your saying you tried a (a) powered USB hub with a OTG cable connected to the phone or you tried a (b) powered USB hub connected with a OTG cable to the MHL adapter and then to the phone?
If it was (a) then there are some vids out there of ppl using powered USB hubs.

Very interested in this.,,
I'm puzzled that there aren't any more postings about this kind of stuff. I was expecting the GS3 to be easy to use as a "PC" replacement but it seems no one besides us few wanted to do that ? A simple cable should have done it but I'd even be willing to shell out 40-50$ for a decent dock that would do just that

http://www.amazon.com/Micro-USB-OTG...UTF8&qid=1343846045&sr=1-3&keywords=otg+cable
Have my keyboard and mouse plugged into the usb hub and then the usb hub into my usb OTG cable which of course plugs into the S3. Everything's working on my end.

You are not reading it right.
they want to use the MHL adapter, too.
As far as i can tell, the MHL adapter needs to be in the phone, not a hub. it is all dictated (the output being OTG, or MHL) by the impedance of what is plugged in. It is an either or situation.
Perhaps with a firmware update they MIGHT be able to run both signals and split it.. but i doubt it.

[Q] If I use a usb hub, can I attach an ethernet port, and have the device charging?

Title says it all, has anyone tried this?
From what I've read (and the other threads on this topic) - no it can't be done.
It can't be done my friend
I got it to work

I used the following and plugged into my TV usb port and had ethernet (verfied with WIFI shut off) and it was charging.
USB 2.0 Ethernet adapter - <amazon.com/gp/product/B003VSTDFG>
OTG with power - <amazon.com/gp/product/B00C452XFO/>
Yup, this now works great for me too! :good:
I bought the Ethernet adapter Nvidia Recommends (same as browncoatdave's)

And just whatever Y cable could find that didn't look uber cheap.

1) 3 Port USB Hub
2) Plugable USB 2.0 to 10/100/1000 Gigabit Ethernet LAN Wired Network Adapter
3) Micro USB Host OTG Cable with Micro USB Power
4) Smart Touch Mini USB TouchPad Keyboard
5) Full Size trackball mouse
6) Charging cord
I am charging the battery with ethernet, keyboard and mouse plugged in.
No Problem. But this is also after the kitkat update which added the charging while ethernet is plugged in.

Did you plug all the devices in a particular order? I noticed that if I plug in my charger AFTER I plug in the OTG cable into the shield, then it is not charging. But when I plug in the charger into the OTG cable and then plug it into shield, it is charging.
Is your hub powered? What exact model is it? I am asking because I have very similar setup to yours but the shield does not detect USB devices connected to the hub - it's this one: http: // esperanza . pl/esperanza-usb-2-0-hub-4-porty-ea116,182,437.html
I can connect one usb device directly to OTG cable and it works, but when I connect a hub, it no longer works.
There is a cheap way to do this if you have the soldering skills, and are willing to try it.
Get a cheap USB "Travel" hub.
Open it up, and replace the Upstream USB cable with an OTG cable (A scrap Micro-USB cable may or may not work. The connector must be Properly wired for OTG).
Remove the main power diode in the USB hub, and solder jumper the 2 pads where it was. A Multimeter in continuity mode can help you find the right component, but it takes some experience. There usually is not much in a cheap travel hub, so I can usually find them just by looking, but like I say, only try this if you have the experience, and you know what you are looking for.
Power the hub through it's 5V power jack (if it has one), or you can add a power only micro-USB socket. (Only connect the (+) and (-) power pins, do not connect the data lines. Connect it to any one of the Full size USB port's power pins. Observe polarity.)
Voila! You now have 4 Full size USB ports, it will charge your device, and provide power (Up to the rated power of the AC adapter) for your USB devices.
I did this years ago in the Nokia 770 days. It was one of the first consumer devices that supported USB OTG. Article still exists here:
http://www.linuxslate.org/N770DockingStation.html (Scroll down to the "Electronic Components" Section)
Would this work?
Would this: SODIAL(R) Micro USB Host OTG Cable with Micro USB Power plus this: AnkerĀ® Unibody 3-Port USB 3.0 and Ethernet Hub
Give me the ability to charge tablet, use Ethernet and additionally connect USB mouse and keyboard, and possibly charge Nvidia Game Controller?
Or would it just be a waste of time and money
