HDMI and USB at same time - Samsung Galaxy Tab Plus

Hi,
Saturday I had some time to open the HDMI dock (for Galaxy Tab 7) and mod it to have alternative power input.
After that I was able to use the HDMI output and USB host at same time. The setup is:
- HDMI out for Samsung TV
- wireless USB keyboard
- external HDD connected with a powered HUB
In this setup I was able to use the keyboard and video files from external HDD while watching on TV screen.
The only problem is that the "MTP Application" notification is still there and the tablet is not full powered from external power supply, it discharges slowly the battery.
After some investigation I've seen that on the original charger there seems to be some resistors between USB lines and Vusb and GND. If I connect the original charger (not inserted on power outlet) the tablet is full powered and the MTP Application is not displayed (when I put the tablet in dock). After that if I remove the cable and insert the USB host cable everything is OK and tablet is full powered with USB host and HDMI working.
The docking is powered with 5V/2A PDA DC adapter.
When I'll open the dock again I will make some picture.
Your are welcome for questions and suggestions.

HOW MUCH?
Cant believe this is my first post on any message board EVER but what better reason! First i would like to know how much would u charge to make the modification for me? I would provide the dock and any other materials that u need of course. Secondly, since the dock works with ALL tab variants(PERSONALLY ONLY TESTED WITH P1000, P7100, P6200, P6210 BUT 99% CERTAIN), u might want to post your development in every other versions forum. I believe this would generate a LOT more interest in this project because there actually has already been a few threads created in which several attempts were made but no one could find the magic combo(plus it could mean a few extra bucks in your billfold!). I waited to post in hopes that u would update with pictures and/or a tutorial but still would rather you perform the actual surgery. Congratulations on accomplishing what samsung should have done from the start...a TRUE multimedia dock! I guess the only suggestion i could offer is if it were possible to actually add a few usb ports into the base of the hdmi dock itself, which is how i feel samsung should have made it originally...definitely not a priority.
Here are a few reference threads if interested & i've already provided a link in each one pointing to your original post for those interested (hope u dont mind!)

Sorry, but I can't do this for you.... It's complicated.
Now I work to found a solution to put an USB connector on the dock and to put a power connector to.
The big problem is that the tab enters on MTP mod when powered this way. As described on other threads there is a way with USB lines to activate full external power.
When I'll have a full modification dock I'll put some pictures and instruction for that.

waiting for pics and further info please...

Galaxy Tab Dock modified
Now I have a full functional dock, modified.
So, after receiving the Galaxy Tab Plus media dock from ebay I've found that I can change the tab fixing part with the one on the old Galaxy Tab Dock.
So, now I have old Galaxy Tab multimedia dock full compatible with my Galaxy Tab Plus.
Then I modified the dock to include standard power jack and standard miniusb connector for OTG.
The USB Host is powered from the external power supply, this helps to not discharge the battery when using tab and slow charging.
I made some pictures with details for connections and modification.
You can view at:
http://www.flickr.com/photos/buzdumil/sets/72157630734690786
There was some work to do...is not very easy. The best thing that can be done is to make a PCB. That PCB, at in my pictures, could be fixed near metal weight. Also there the clips of the case need to be cut, but there is no problem because at same position exist screws for fixing.
The problem with MTP application started when power connected or tab inserted on dock remains. But now is easier to use external HDD, usb keyboard & mouse and television to watch movies.

That's amazing, Emil! That's the dock accessory Samsung should have sold in the first place. After looking over your pictures, I'm ready to go order a soldering iron and get to work!

Hi emil b just letting you know i was playing around with my dock and found how to get rid of the red x from when power is applyd.
First connect power and get red x....
Then disconect the earth and re connect it again..
This forces AC Charge mode...
No resisters or shorting data lines are needed..
So good for being in host mode...
All you need to do is put a on/off switch inline on the earth
Where you supplied power to the dock.
Doesnt need to be inside the dock..
Give it a try and let me know...
Just have to play with it and hit switch a couple of times...

Im looking at all options concerning the modification of this dock. One question that comes to mind is: If I only use the red and blackwires to send power to the USB connector, will I still be able to use the OEM 30 power connector??

OP, I am going to attempt to make this modification myself. Would you be able to provide any additional instructions/suggestions to the pictures up on Flickr?
Thanks,
cypher

No because the origonal charger has the resisters on the data lines...
you are better to add just power to pin 7(9) and earth to pin (1)30..
then add a otg dongle..

[Q] Can the XOOM act as a USB Host?

Hi, can anyone who owns a XOOM pls let me know if you can plug in:
1) a USB flash drive to the XOOM, and view and open files on the drive?
2) an external hard drive and view and access files from your XOOM
Many thanks

Does the Xoom have a USB port? Pretty sure it only has MicroUSB. I guess they do have microusb flash drives not that I look.
Hi. Yup its only got micro USB, but I guess you could use the included adapter cable to plug in a flash drive.... we don't have the XOOM here yet, but the functionality of being able to connect a flash drive, move files e.g. PDF or .doc and then view them is important to me.

As of today what you want is not avab. The cable it comes with doesn't take input. They do have a cable online that will do this one day, but doesn't do it yet.

The cable that Motorola "will" be selling is a micro-usb to standard usb (female) adapter. I'll look around for the sources, but I know that I saw this detailed in a few videos from Motorola techs and at least one reviewer site.
The cable is not just a straight conversion of form factor, but has the necessary pinout to instruct the Xoom to jump into usb host mode. From the reports that I saw, it would absolutely provide the ability to plug usb drives, cameras and other accessories into the xoom for direct access. In fact, the reviewer that I saw, made a comment that they had verified the functionality by plugging in a couple usb keyboards... supposedly worked like a champ.
Lame that we need a "special" adapter, but I can imagine that if it is just a pinout issue, it may be possible for the good folks here at XDA to craft a software solution that would allow us to bypass the motorola-branded cable... It would have been WAY cooler if it was a standard usb port, like some of the other tablets on the horizon.
Thanks. They mention in many reviews and I think Google mentioned it too that you can attach a mouse or keyboard by cable (I know about Bluetooth) which suggests that it should support input, so is it just a hardware interface thing or an actual firmware OS/software issue?
Edit: thanks for the great response gigglebox.... we posted simultaneously
Is this it?

Visually, yeah. Looks like they took it off their site for some reason. In fact the only times that I saw this on Moto's site, was in the day or 2 leading up to the launch... when typing in xoom into the search bar on their landing page, it would spit out a drop-down menu listing the Camera Connection Kit (by name and pic).
I dont like the fact that they call it a "camera connection", but they werent pulling any punches about it serving as a host. They did note that the external storage (thumbdrives, etc) were not yet supported, but that they would be. The cameras and (according to them) keyboards were working now.
I believe it is possible but right now it is a software limitation.

Agreed, the engineer from moto definitely says the hardware should accept any usb 2.0 or higher device, but it's a software issue. Toshiba have a straight usb and a micro usb port on their device so hopefully they're working on this.
We don't have the XOOM here yet, but hopefully by the time it becomes available (approx April) we might have the option of the Toshiba as well.
I use this USB host cable and it works great. Have tested it with my 750gb Oyen and 320gb WD Passport external HDD's, several usb flash drives (8-16gb), San disk USB memory card reader, and a USB keyboard.
For those having issues getting their Xoom to recognize USB storage devices here's what I've got and did to get it to work: I flashed my XOOM (3.1) to the 2.6.36.4 Tiamat_Xoom-v1.4.4-Full_Throttle Kernel and was unable to get the USBMount to recognize drives or storage at first. I installed USB Mass Storage Watcher from the market (it's free) and it works awesome! Can mount any storage I want (NTFS, FAT16/32, HFS, HFS+, EXT2, ETX3, EXT4) with any capacity. I think this app will work with any rooted Xoom (or other devices). Under my Kernel my USB host is located under/usbOTG.
Hope this helps.
FYI ... I've checked it and stock ROM Xoom without root is able to operate standard PC keyboard/mouse using basic one-to-one usb->microusb adapter (without any electronics onboard).
Probably with proper dual socket usb adapter (also without electronics onboard) it would be possible to connect both keyboard and mouse at once.

if you have a Logitech keyboard and mouse that connect by the unifying receiver,or mostly any keyboard+mouse combo that connects by one receiver, then only a standard OTG cable should work.

Notifications/Charging Questions

Hi all,
Just got my Infinity+dock, and I have a few questions:
(1) With the dock connected, there is a persistent notification of "Docking connected". It's quite obvious to me that the dock is connected: I can see it, I can see that the dock battery is charging, I have a mouse pointer, etc., so I don't really need this notification. However, I can't figure out how to turn it off.
(2) Similar to #1, with my MicroSD card connected, there is a persistent notification of "External storage inserted". Again, I know it's inserted, I put it in there. Is there any way to turn this notification off as well?
(3) I am having an issue charging the tablet and/or the dock via the included USB cord. If I plug the cord into a different wall unit or into my computer, the USB won't charge. (However, I know that it works because I've successfully connected the tablet to the computer.) The only time I can successfully charge anything is if I use the included wall unit. I would appreciate some help, as I can't see why a different wall unit or my computer won't charge the tablet/dock.
Thanks in advance!

- go into settings menu and click on ASUS customized menu
- Scroll down and to Use ASUS Quick Setting and uncheck the box
- Now click in the bottom right of the screen to bring up the quick menu
- With the quick menu up, click anywhere in the top portion of the menu (where you see the time/day/date/wifi/battery) and this will expand the menu vertically
- Toggle notifications to OFF
* keep inn mind this will also turn off notifications for emails/sms....
(3)
I only use the included wall charger so i cant comment on other wall unit charger. As far as charging via USB, no issues here using the included USB cable. Any chance you can trying another USB cable or trying a different USB port on the computer?

hhhhmmm...just notice the following
The tablet does not charge via USB to computer, it only connects to allow transfer of files between tablet and computer. The tablet only charges if:
1. USB cable is plugged into wall charger unit and connect tablet or tablet with keyboard dock
2. If tablet is docked the keyboard and plugged into computer via USB.....however, only the tablet charges.

Your comment about (1)(2) is not true. This will not get rid of the persistent notification at all. The only way I am aware to get rid of them is with some custom roms. I can not comment on the third part though. I do not have knowledge in that area.

Actually, it *does* get rid of the notifications for the dock and SD card. Problem is (as the OP states) that it stops *ALL* notifications, which makes it a not-so-desirable "solution" to the problem...
Trust me - I just tried it and the keyboard and SD icons disappear completely...

The notifications:
I would have never in a million years found that setting. However, turning off the notifications didn't turn off the "docking connected" and "external storage inserted" notifications. I tried restarting but still no dice.
Charging:
I only have the USB cable that comes included with the tablet. I tried different USB ports, but I can try other computers. However, I had a thought: the best computer I have only has USB 2.0; maybe USB 3.0 is required to charge the tablet?
It still doesn't explain why it won't charge if I plug the cord into a different wall unit: for instance, an Apple wall unit or a 4-USB wall unit that I have.

Tablet requires 15V(correct me if I'm wrong) which is supplied by Asus accessory wall plug.
Computer's USB ports does not supply enough voltages to charge the tablet, however I haven't tried USB 3.0 port to charge the tablet it might work but I highly doubt it will.

My CX-919/Measy U2C-D/Belkin Ethernet/USB 2.0 Hub combination: "Frankendongle"

My CX-919/Measy U2C-D/Belkin Ethernet/USB 2.0 Hub combination: "Frankendongle"
I have been tinkering around with my CX-919/Measy U2C-D dock since I purchased them and wanted to show off my results thus far.
I wanted to add features while keeping the whole system as compact as possible. I also didn't want to block any of the connectors or ports so that I could maintain maximum flexibility and usability in the system.
The CX-919 has its own Micro SD slot and the Measy dock adds an additional full-size SD slot as well.
I would call this system 99% complete, as I'm building a custom cable that will bring power to the USB hub via the micro USB connector on the dock.
I'm using the coaxial power connector next to the micro USB connector with a 2.4-amp adapter for power. The two are hardwired in parallel so by utilizing the micro USB connector for power I can fully power the USB 2.0 Hub.
When the cable is finished the system will be considered "complete".
(I have the pieces here at home. but the "good heat shrink tubing" is at work so I'm waiting in order to make a better looking cable.)
I present for your entertainment: Frankendongle
The system:
*CX-919 Android Mini PC -modified with Finless ROM and copper SOC heatsinks. (A very fast and stable runner)
*Measy U2C-D dock -modified to allow full horizontal rotation and a layer of Velcro for mounting other devices
*Belkin USB-to-Ethernet dongle -modified with Velcro to secure it to the U2C-D dock
*USB 2.0 Hub (make/model unverified -eBay purchase, but any Android-compatible hub that fits the space will do!) -modified with a longer USB cable to allow for use with this system and Velcro to secure it to the U2C-D dock
Top view showing off some of the system's footprint and copper SOC heat sinks.
Front and rear views.
I wanted one free USB port on the rear for use with a USB hard drive.
The dock acts as a USB Hub on its own, and I wanted the Hard Drive and Ethernet adapters to only go through one USB hub for better performance. It's for this reason they are plugged directly into the dock itself and not through the additional USB hub .
Currently the system is being used with an iHome wireless keyboard/mouse for which you see the receiver plugged into the 1st USB port on the hub.
Side view.
This shows the Ethernet connector as well as the USB Hub's coaxial power port.
When completed, the custom power cable plug into this port to fully power the hub and allow for compatibility with the widest array of USB gear.
I use the system as a secondary one for surfing the web and watching videos when I don't want to fire up my big Windows PC. It also works great for retro gaming which I'm fond of.
It's certainly not the prettiest setup, but like I stated earlier it is very compact and works well for it's intended purpose.

USB OTS + Charging issue

Good evening guys, I'm starting this post since this is the only issue preventing me to buy an Nvidia SHIELD Tablet at the moment. As the thread title suggests, it's about the charging the device while using the MicroUSB port as a Host in a USB OTG (for example, to be able to Gamestream at 1080p using a USB Ethernet card). I tried to find another thread in here about this, but maybe it just hid from me (in which case, I apologize, and please, refer me to that thread before closing this one). I can link you to some outside-XDA forum threads about this, but I'm not doing it by now since I don't know if outer links are allowed.
Anyway, back to the topic, I don't own a SHIELD (yet),only waiting for this issue to be solved. I'm so sorry but in my opinion, the SHIELD Controller is not even close to the 60 USD worth point as a controller, so I'm using another one, and one of the features that made me decide for the SHIELD Tablet is the Gamestream possibility, but with Keyboard + Mouse, not only with controller, feature that I want to use my PC peripherals with. Also, I'd be using a USB Ethernet card for 1080p Gamestream.
Considering the previous points, plus it's by all known that the battery life of the SHIELD is not specially awesome when it comes to gaming, I consider being able to charge the device while gaming (in any condition, including using some devices through the USB OTG HUB feature) a must.
Wondering around, I came to think about two hypothesis:
1) SHIELD's kernel has not the USB host + charging feature implemented, which, as someone around here said, it'd be a serious case of false advertising.
2) SHIELD's kernel actually has the USB host + charging feature implemented, but somehow, it's not activated on the build.prop, in which case, the solution would be as simple as modifying the root/system/build.prop file, adding the following line: # support USB Host rp.usb_host = 1 (you need root permissions to do so. Be sure you make a backup file!)
I'd greatly appreciate if anyone in the forums could test it, so I'll be able to purchase my brand new SHIELD Tablet without the fear of having it only as a regular tablet until Nvidia decides to offer the features they claimed they will (which honestly, is pretty sad...)

Just FYI, if you are going to copy/paste the same info between forums make sure you typed out commands correctly.
should be:
ro.usb_host = 1
NOT rp
EDIT:
Seems saving the file errors out even rooted...Not sure what to do.
EDIT 2:
Doesn't work. Tried it with a Build.prop editor.
Side note: When it is "charging" the AndroidOS doesn't see it charging but the port lights up orange. Doesn't look like it puts out full amps.

TYVM for the attempt... then it's just that Nvidia totally made this feature out of nowhere... Well, let's have hope in the Android Development comunity...
Oh! And thanks for the correction! OMG I misstyped it... Gonna correct it on the GeForce forum ATM.
So, does a USB hub works with the Shield? Charging while using wired peripherals..

My Samsung S9 has had some screen damage and the touchscreen mostly does not work.
In order to navigate it I must use a mouse that I connect to the phone using the supplied USB C- A adapter.
I wish to get my phone repaired but I wish to backup all the data upon it first.
If I plug my phone directly into my PC, it asks for my permission to allow the PC access. However, since the touchscreen does not work properly, I cannot press the button to accept.
I could not plug both the mouse and PC simultaneously.
So I bought a USB-C hub. (Actually I've bought several, none of them have worked, this latest one is the most expensive and I had hoped it would work - (https://www.amazon.co.uk/gp/product/B07ZVKTP53/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1).
It has a separate port for USB-C Power Delivery and a separate one for data.
I plug the attached USB-C cable from the hub into my phone, and then I plug my mouse into a regular USB port, my charger into the USB-C PD port, and another USB-C to A cable from the USB-C Data port on the hub into a USB port at the back of my (new) PC.
Now my computer does not recognise my phone at all, nor does my phone seem to acknowledge it is connected to a PC. The mouse still works upon the phone and it charges fine through the PD port. If I plug the phone straight into the PC, it is recognised, so I do not think the problem lies there. The hub seems to block communication between the phone and PC.
I would like to backup my data and get my phone repaired. If anyone can solve the USB-C Hub issue or propose another solution to my problem then I would be grateful.
A mouse and keyboard will take priority over anything else in a hub.
I'm betting the hub's power is 2000mA or 2.0 Amps.
What does your fone charger state its power is? Add the mouse, keyboard, and fone's milliamps together. If it's more than the hub's power pack supplies....
In this situation, I would use Vysor, this will defo solve your problem, it allows you work with your fone on your pc/lappy by providing a lovely window that is a duplicate of your fone screen, you'll be glad you found this!!!
I can provide an old cracked version I used for my emergencies, if there is no objections?
Then you'll only need the mouse to use as your finger
Google Vysor. case closed lol.

Hi
Thanks for your reply
It's not a battery hub, but just a USB-C hub (check the link). Power comes from the PD USB-C port which is hooked up to my phone's original USB-C charger.
It also fails to work even when a mouse isn't attached to it.
I will look into Vysor. Also thought about the possibility of using a standalone bluetooth mouse which would free up the cable.
Your fone will suck the life out of a poorly powered hub, by using vysor, your pc/lappy mouse will work your fone using vysor, best app I've ever seen for working with broken screens, just plug phone direct into lappy, vysor works if you've no screen at all!!!!!
Use
Vysor

Dont pay for mouses/hubs in this scenario. Just pay for a top quality tool. I would place this as my number one android tool for ANY fone.
Again, if all your doing is data recovery (saving your stuff) I have a patch for an earlier version to unlock full version I swear by, you could use this once if only to try before you buy
The hub supports 85W fast charging directly from mains, which is what it is getting.
How do I enable USB debugging specifically for the app?
I have enabled it in developer options but when I connect my phone via USB to my computer as per the Vysor app, another window pops up on my phone asking to allow USB debugging. Ask there is no mouse attached to the phone at this point, I am unable to allow it.
