[Xoom2] Usb Hub+uHDMI Adapter - Xoom Q&A, Help & Troubleshooting

Hello there!
Guys sorry if already has something treated about this around here ( I did not found), The problem: My Xoom 2 are starting normally but the touch screen not "answer" the commands..
Its did not down or was kick out or something like this... ( at least were what my wife said ).. The workaround:
I can't buy the new screen for now, so I put one usb hub (It is energized) , on this I put mouse and keyboard, and still are using micro hdmi adapter for the monitor, on really its on micro hdmi adapter + dvi on the other side ( because my monitor dont have hdmi port , just vga or dvi )..
Although of all this , are working, but its froze the screen after some minutes( 3 / 5 minute +/-).. I already left some option "on" in settings( not turn off , usb depuration..).
Please, what would can I do to make its works less stoped? Can I turn off the screen on the Xoom and let just working on the Monitor?

[Q] Wifi Sleep Policy [+ USB Adapter]

Hi all, i've got two newbie questions.
First: if I set WSPolicy to "When screen turn off" it means that my TF will disconnect when I close the screen, whatever is it doing in that moment?
I mean, if i'm downloading a file, will the download be interrupted OR the wifi sleep policy works only when there isn't data trasmission going?
Second: I've got my TF101 without the dock. If i buy a female-female USB adaptor and use it with the USB cable that I usually use to connect the TF to my laptop, could I use USB host? Like read an USB pen, or playing with a joypad?
Thank you all in advance.

for your 2nd Q, the tf uses a USB 3 cable, and AFAIK there isnt female to female USB 3. they are selling a USB adapter that plugs into the charging socket. http://liliputing.com/2011/08/asus-eee-pad-transformer-usb-adapter-other-accessories-coming-soon.html .
for you first one my tf has continued downloading even when screen is off. i've set to never when plugged in, but i've notice that when there is no activity it turns off the wifi, cause when i turn on my screen it take a sec or 2 for the wifi to turn blue.

HDMI and USB at same time

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.

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..

HDMI MHL - Shutting off phone display while connected to Sentio Desktop?

Working on a project to turn my phone into a desktop without a need for too specialized adapters and without root. Using my LG G5 for testing this. Have a MHL USB Type C adapter that contains USB, HDMI, and Type C in (charging). The setup works well, and I'm able to hook in my keyboard, monitor, and mouse perfectly. Screen resolution is slightly cut off on the top and bottom edges. It seems to mirror the display of my device. Could imagine it troublesome for taller phones like the S8.
This can be fixed without root, as you can give Sentio Desktop permissions to edit the display settings.
HOWEVER, I don't see anyway to turn off the display when plugged into the adapter and keep running the same.
This is more of a long-term problem. Having the screen on for extended period of time will cause heat issues, not to mention wear on the screen.
Is there any kind of way to turn off the phone's display when hooked in, akin to closing the lid on a Mac when hooked to a monitor (without root preferably)?
Did you ever find out how to do this? Bugs me too!

Anyway to backup with black screen/dead touch screen, no usb debug? HDMI to type C?

Hello everyone,
I would really like some help advice/experience from other here regarding the HTC U11. I was just using the device normally one day and the screen went black completely. I think the touch screen is dead as well, as it doesnt seem to respond when I attempt my usual pattern unlock from muscle memory. I am sure the device is still working normally as I had... accidentally connected to emergency operators, could still use Whatsapp Web and my PC does show HTC U11 but I am unable to change the option to MTP to transfer my files.
Does anyone have any advice on how I can access my data through enabling usb debugging/ changing the connection mode to MTP? Apart from repairing the screen only.
While I am not sure about the software options. I am attempting to output using a Type C to HDMI hub to output display and use a mouse to access the phone. Since it was rather hard for me to find answers about the compatibility and usage so I was hoping to get some experiences so can quickly attempt this method when the few cables I purchase arrive.
1) Are these type C to HDMI cables generic? I have seen some articles saying there are type C to hdmi with MHL and others with digital output and I confused if those I bought will work with the U11. (Seller says works to Macbook, Xiaomi, Huawei P20)
2) Are these adapters simply plug and go? Do I have to unlock the screen or install any firmware (as I clearly dont have a screen haha..)? Does this apply for both the HDMI output and using a mouse
3) Would I specifically need a SMART TV with HDMI to get output out or any monitor with HDMI would work fine?
If anyone have a working U11 and using HDMI to Type C would really love to hear from you!
Thank you for any advice/experiences in advice!

Control phone with broken lcd

Hi
I have Galaxy Ace 4 (kitkat 4.4) with broken lcd. The screen is blank but touch should work. Earlier something was visible on screen and as I remember touch was working.
Moreover, the system had some failure due to permanent "application xxx stopped working" and factory reset should be made.
I would like to use this phone as wifi hotspot. Is there any way to access the phone after factory reset? I have found application like Visor to control android via usb on pc. But developer mode has to be enabled and I'm not sure if system should be rooted.
Thank you for any help
If you can still see the screen, but the touch screen does not work:
Buy a cheap USB adapter so you can connect a PC keyboard or mouse (probably a USB C to USB A adapter). You can buy these adapters from China on eBay for $ 1 (but you may have to wait a month until they arrive in the mail. In this case, buy from a seller in your own country). I suppose you have a keyboard or just use the keyboard and use the arrows to move and select things, so I think the Windows button will become the home button. Press Enter to select and Escape to return. Or you can simply point and click with the mouse. The problem is that not all phones support "OTG", so you may not be able to read the adapter. If so, then I think you have no other choice. . But most of the stores themselves definitely support 100% OTG, so it should work normally. The problem with Bluetooth is that you need to pair it first, which requires touching the screen. Therefore, if you cannot touch the screen, using a Bluetooth mouse or keyboard may not work
If you can't see the screen, but the touch screen works normally:
Unless you change the screen, don't think that there are many things you can do. Android phones that were previously compatible with MHL allow you to use a dongle to connect it directly to HDMI. But the cell phone no longer has that function. If you have a Samsung phone, I think you can buy a Samsung Dex docking station, which will allow you to connect it to the screen via HDMI. If you can install applications on your phone, you may be able to control your phone from your computer using a screen mirroring application (there are thousands of different software that can do this, but you need to install applications on your phone). Same as Google Chromecast screen mirroring. .You need to access the application on your phone to perform this operation. Therefore, there is nothing you can do except replace the screen. If you are lucky and your smartphone supports some type of HDMI dongle adapter or some type of desktop docking station with HDMI output, you can view the phone's screen and access it.
