SM-T550 capable of OTG and charging simultaneously? - Samsung Galaxy Tab A series Questions & Answers

Hello, so I recently purchased one of those y connectors off ebay for a very pricey $0.99 that supposedly will allow otg and charging at the same time. Despite the sellers claims of it being compatible with "any phone/tablet that has otg" I can't get mine to charge, no matter what order I connect everything. Otg works, but no charging. I also tried on my LG K20 Plus, and same issue. Am I doing something wrong or missing something here? Thanks for the help.

Hey Escott31, Did you ever get an answer to your question? I have been on and off thinking about this for a few years now but never gotten much further than trying a 100K resistor from ID pin to ground which I couldnt get to work. Any luck on your end?

Car Chargers Compatibility

Done a brief search on here and cannot find the answer to my question.
I have a standard car charger which I used with my my XDA Orbit (Artemis) - i'm presuming I can use this with the Touch HD? Just that I read that the connector is slightly different on the THD....
I'm also quite tempted to get one of these CC-C100 models with the HTC logo at the top (i'm not vein, honest ). Would these would work too?
May sound like a stupid question with an obvious answer, as I know they all have the generic mini-USB connector, but just wanted clarification.
Thanks
I was wondering the same.
I picked up somewhere that the normally unused B pin of the 5 pin mini USB needs to be connected to ground to enable 2Amp charging. Othewise it may max out at 500mA. So many of the chargers sold as HTC compatible will work but will not charge full rate.
The nice one with the HTC logo do have a ExtUSB connector and are rated for 2000mA so should work full charge. I am waiting for my eBay order to come in to validate.
Any miniusb car charger should work. I bought a satnav car charger and it works fine.

[Q] Is my micro usb port broken? Help!

Guys,
I have a A501 32GB 3G model and I think my micro USB port might be broken.
I can't remember when but at some point, my computer stopped recognising my A501 when I connect to it via micro USB. For awhile I thought it might the custom ICS rom's fault as the normal USB port wouldn't work either, but when I reverted back to Honeycomb this week I noticed the normal USB would work, but my PC still couldn't recognise the tablet when connected via micro USB.
Is there any way to test the port? I don't even have a spare cable I can try to see if it's the cable's fault.
I'm planning a move overseas in a few weeks time so I don't think there's enough time to send it in for repair under warranty. What a hassle....
Has anyone experienced same problem? I don't really use it much but it bugs knowing something's broken when it's only 4 months old...
Thanks in advance.
Mine has intermittent issues, but in my case, it is the cheap cables I'm using.
I would go to Best Buy and pick up a cable (normally I would say order one from Newegg or somewhere like that, but it appears time is of the essence in your case) and see if that isn't the problem. Or...borrow a micro USB from a friend. Either way, try to eliminate the cable quickly (as that is the easiest and quickest route to go).

Sounds good. But, I also might try re-loading the PC's drivers for Android also.
Never heard of a micro-usb going bad. Not yet anyhow.
Micro USbs fail on phones all the time, it usually happens when the user isn't delicate with the connection while unplugging or plugging in the cable. The port technically doesn't fail, but the soldering connection to the circuit board does. I would first look at a bad cable. Don't you own a cell phone?? Even Crapberry uses micro usb for its charging data cable now try your cable from your phone or digital camera??

HTC ONE OTG not supported/MHL playing up

Any info on this would be well appreciated.
Don't know if this is already covered somewhere but I can't find it. I'm well gutted about this, Just tried watching a film on HTC ONE with OTG cable and it doesn't work. I get a warning notification saying " unable to charge device, please use supported charger " Gutted. I thought this would of been covered since the one-x supported OTG when it got 4.1 update. Also, don't know if it's related but the MHL (an official HTC 1) isn't working properly either as it did on my one-x. It wil be playing fine for 20/30 seconds and then cuts off for 10 seconds then comes back on. It's does this repeatedly which makes what ever your trying to watch - unwatchable.

It supports OTG
Haven't tried mhl, but otg works fine here.
Tried it with my memory sticks and fiio dac.

Seem to be working now. Must of been the memory card adapter I tried, tried another one and ok now but still getting error notification " unable to charge device, please use the supported charger " Don't know what that's all about. Keyboard and mouse work fine with OTG, never tried them before.

Definitely something wrong with MHL.just tried again with official HTC adapter and flawless on one-x, unstable on the ONE.

Isn't the one purportedly MHL 2.0? Maybe the adapter needs to be different...

I just tried MHL on my One using the official HTC M490 adapter (NOT the M500 which I think won't work). I have no problems at all with MHL. It is stable. I don't know what difference MHL 2.0 makes, but I did notice that the phone seems to be capable of outputting something different to MHL out, vs what is on the phone screen.
For example, and I have no idea why, I seem to have a free copy of Thor on the phone under the HTC Watch application (freebie?). I found that when I choose Thor as the film, the phone screen is showing a synopsis, while the TV is showing a still frame from the movie. However, when actually playing the film, both are showing the same thing. Nevertheless it is a good indication that dual screen gaming applications may be possible for example.
Also tried the OTG using a Samsung usb adapter. No problems functionally but I can confirm the misleading error message about not being able to charge the phone. No problems accessing the USB storage though and Gallery automatically will find pictures on an externally mounted SD card.
HTC M500 adapter has 12 pins and was the adapter for HTC tablets (Flyer and Jetstream). The majority of connectors use 5 pins, except Samsung (SIII and Note 2) that uses 11 pin, which allows for MHL and USB OTG simultaneously.
Regarding MHL 2.0, it has the ability to pass 1080p video at 60Hz (up from 30Hz of MHL 1st generation) and charge up to twice as fast. Samsung SIV has it, but I haven't find anything official that shows HTC One also has it, or for the need of a different adapter.
All the MHL adaptors i've seen (mine included- Cablesson) have a micro USB slot so you plug in your charger* to that, then the device to your phone, and it charges as it outputs.
Are you all doing that, or trying to output with no charger attached.

I have no problems but to confirm the adapter won't even start-up if you don't connect the charger...it is totally ignored. I am assuming the original poster either has a bad USB/MHL port on the phone, or the adapter is slightly out of tolerance with its connections hence working on some phones and not others.
I've bought an adapter on ebay for my One X. Besides ths usb charging port having issues, it messed my One X usb port - it only worked with the adapter pluged in. I had to reset One X. So, mhl adapters can be really a mess.

First day with phone today so briefly trying lots of things, I had pre-bought cheap ebay MHL adaptor and tried it with a few youtube videos seems to work OK (confirm you must have a charger micro-usb MHL).
It did give about 20 secs of white snow interference at start almost as though it was tuning in channel but steady after that.
More investigations to follow I think.

How did you get on after more tests?

if anyone else has a 100% working MHL to HDMI can you post which one and where to purchase.

Sucks that I don't have mine yet. I have two different MHL adapters I could try.
I just experienced the original "HTC AC M490" MHL-Adpater with my HTC One (Stock ROM).
It was working straightaway, but the device display as well as the TV screen where a little bit slow and choppy.
Is it possible to change some settings (like resolution or frame rate) to improve the performance?
THX
Edit: Is it MHL 2.0 ? (Regarding to this thread it seems to be only MHL 1.0)?

No, it isn't.
The S4 will be the first MHL 2.0 spec device.
Is there any way to set the output resolution manually to 720p?

With a custom kernel you can do this. Flar2 did this for the one XL, I see he's starting to migrate over here.

Yes obviously plugged the charger in aswell with the MHL. The picture is perfect. It just play's for 20/30 seconds then cuts out for a couple and just keeps doing that. Even though the OTG works I still get the error triangle in the notification bar, which I don't on my ONE-X, but I can put up with that.

USB Cable Picky?

I'm going straight to the point.
Does the redmi note 7 is picky when choosing a type-C Usb cable?
I tried to charge the phone with the nintendo switch type-c usb, but it won't charge.
Last Saturday i went to buy a type-C cable a good brand around 12.00 $ but it didn't seem to work. i bought a random one from a store "miniso" the old telephone line cord ones. And it actually charge it.
what i want is a usb that is larger than the one that comes in the box (.
A. do i have to search for specific brand or something?
anyone know why? need had seen this problem before

Sounds like you were the victim of a proprietary cable followed by a faulty one.
Redmi Note 7 uses any standard USB type C cable.

Any cable works for me. I've used the macbook cable as well as a 3rd party one.
My RN7 won't charge with micro usb cable and USB-C adapter.
With another device - Huawei - it is working without problems.
I think the RN7 is picky

Dead usb port?

Hi guys, I'm new here and could really use some help
I finally upgraded to the 6T from my OP2 yesterday. I got a T mobile variant (in great condition) and wanted to convert it to international. The problem is I can't seem to connect it to any computer. I have tried 5 computers and 3 different cables, the phone just doesn't get detected. USB preferences remains grayed out and windows doesn't even detect something is being plugged in.
I have tried installing the OP drivers, and qualcomm drivers, made no difference.
I also noticed that the usb-c to headphone jack doesn't output any audio through my earphones. Dash charging isn't working either.
Is my usb port damaged? It seems like theres no data going through it at all

Well if it's not even charging or playing audio then yes, I'd wager the USB Port is damaged.

Regular charging works, just not dash charge. And the buttons on my earphones can play/pause music, but there's no sound output. I've been reading a few pixel forums, this seems to be a common issue with pixel 3's. Was just hoping to see if others here have faced similar issues and how they got around it
Have you tried to clean port with toothpick or brush also your dash lead or charger may be faulty, dash charging will only work with dash lead and dash charger. Also usb type c are prone to failure i would clean and replace lead and go from there before juming to charge port replacement, if necessary ctdi in poland do a great job and authorised repairs for oneplus
