Hi, I'm planning to build my own docking station and need some informations about the HTC Desire micro USB connection and the internal resistance of it!
The USB charger by HTC in Europe has 5V @ 1A max and I have original standard battery.
I've only one microUSB cable now (none to cut) and the connector is to little for my multimeter
Or is there a technical information data sheet for the Desire by HTC?! That would be awesome!!!
Thanks in advance for every hint!
I would definitely go for the official agreed specifications, as microusb is an EU standard agreed among manufactures. It would suggest that the pinout is also standardized and available. Google it.

Hi Stefan,
Thanks for your quick answer, I checked the USB specifications at www.usb.org already and also the pinout. But I don't want to damage the battery. It seems that there are a lot of different chargers for all the microUSB smartphones.
I will build my own charger, so I cannot buy a standard charger for microUSB - That's because there will be some extra features and It's also a project to learn something for university
An E-Mail to HTC is out - hope they give me some technician sugar
If not, I'll buy a cheap micro USB cable, cut it and let my multimeter do the work...

if it helps at all i also use a micro usb cable from a Nokia without any issues so i would assume the pinout is the same and standard.

Thanks coriron! That's good to know
If somebody needs service manuals: http://www.mikechannon.net/page1.html (nearly all HTC devices, but Desire and Nexus One)
If anybody has the servie manual for Desire/Bravo or even N1 pls post it here.
The main problem here is, that i don't know the internal resistance while loading the battery. Maybe i can only check the battery with my multimeter, but I think the battery is not the only thing connected to the microUSB while loading...so there is a risk to damage something...and I don't want to buy a new Desire
edit: and of course I want the maximum loading power - and there are chargers between 4-12,5V/0,2-1A - (I've seen so far)
edit2: Okay, found some infos about the chargers - when plugged into PC there is communication through the 2 data channels (D- and D+) - When loading on charger it can happen that there is no charging (because of missing information through data channels) - so one has to connect D+ and D- with Gnd - like in most third party usb chargers! Then it should work. Maybe that helps someone later...
edit3: If someone is interested - one possibility to build a charger (european symbols!):

Already had this problem a few couple of weeks ago with the car charger i got for the desire. All i did was open the charger up and short the 2 data pins (middle pair) together, not to ground, and it works fine and i now get the full current instead of the usb limit.
why don't you plug a normal usb jack into the htc original charger and measure everything you want to know?
it should be cheap (you must have some unused cables around) and you have enough space to use the mutlimeter.

Anyone has any personal experience on this? I supposed that due to the 11 pin arrangement of the S4, most generic MHL HDMI adapters that you get from China wont work?
From what i've heard also from S3 forum, the official one from samsung also needs to be plugged in with an AC plug that can supply a good amount of current for the adapter to work?

I have on genuine samsung that I bought for my old S3 and you have to plug it to the charger indeed. And most forums and reviews said the old or generic cables wont work since samsung has changed completly. Dont know if meanwhile China was able to replicated, though. Aliexpress has some deals where the sellers say it works but I wouldnt trust them.
I just got a Official Samsung MHL HDMI Adapter from shopandroid and it came with an adapter for the SGS4. So I would presume (and I could be wrong here) that IF you just buy the 11 pin adapter it should work. Here is a Google search for the one I received today http://cdn-store.smartphoneexperts.com/store_images/product_images/accessories/large/11843.jpg
As you can see the little USB part is the adapter needed for the S4

I have one of this model and it works perfectly on my TV and in my S4.
Most mhl adapters will work with an 11 to 5 pin adapter. However most mhl adapters other than Samsung's new official are mhl 1.0 which is 1080p24. Meaning at 1080p you'll only get a capped frame rate of 24; terrible for gaming.
The S4 has an 11pin which is 2.0 compatible and allows your phone to use a 2.0 adapter without your charging wire and enables the HDMI on your TV to charge the phone (only if your TV is mhl supportive - most new ones are) otherwise it won't charge your phone.
Mhl 2.0 allows 1080p60. Meaning a perfect 60 frames at 1080p. Ideal for gaming, especially if you're using a controller and planning to use your phone as a gaming console. Definitely buy Samsung's 2.0 mhl adapter.
Gets the link to the official 2.0 adapter on Samsung's website.
http://m.samsung.com/us/mobile/cell-phones-accessories/ET-H10FAUWESTA
Amazon is the best deal I've found. Watch eBay, lots of 2.0 ripoffs that are really just a 1.0 adapter.

Thank you for the recommendation, I was meaning to buy one for some time, just slipped my mind a time or two !
was thinking OTG and hub , but what about a together ?
getting my nexus player tomorrow , and realized i only own right angle OTG , considering the below OTG/hub , i know it requires a power adaptor , but i am a junky for ports and power .
any owners see a issue with this ?

A good powered hub is near a must for a device like the NP as there are so many uses for peripherals: hard drives, keyboards, mice, USB keys, Flirc IR controller, usb ethernet, etc. I highly suggest getting a decent powered hub with a lot of ports and a good track record. Monoprice sells a pretty good powered 7 port unit that has great reviews (I have four all over my home) and is relatively cheap:
http://www.monoprice.com/Product?c_id=103&cp_id=10307&cs_id=1030702&p_id=5328&seq=1&format=2
The hub you were looking at above is limited to 3 ports and doesn't come with an a/c adapter. I'd look elsewhere, imho.
So far I have had good results with a bus powered hub. Granted, it's not going to work for a bus powered power hungry accessory, such as an external hard drive. But it powers my wireless dongle for my F710 and a USB flash drive just fine.
I've noticed my Logitech K400 had some pretty bad range issues when the receiver was connected directly to an OTG cable, but when I use a powered hub it's working great. So, it may be worth considering, if you notice any problems with an unpowered setup.
Just want to update. This cord works fine
http://www.amazon.com/gp/product/B00B4GGW5Q/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
I have this one and it works great. I broke my rightangled one trying to force it to fit with the hdmi plugged in...glad they are not expensive.
I bought my right angled USB OTG before I got the unit and also had some trouble getting it in there. The problem was that the power cord was in the way. I resolve it by simply plugging the USB OTG in first and then inserting the power cord.

You are lucky because yours bends towards the power cord and not the HDMI cable like mine did...there was no way of having both installed at the same time.

Hey guys.
This thread is about my Galaxy Note Edge but since it is basically the same as your Note 4's and this forum is more popular I thought someone might be able to assist me quicker
Before my Galaxy Note Edge I had the original Galaxy Note (N7000) and connected it via MHL to my Pioneer AppRadio to fully mirror my phone and it worked perfectly.
The Pioneer Android kit looks like this and comes with MHL...

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
So today I tried to connect my Edge to the AppRadio and it does not work :crying:
I have checked the power and when I connect the MHL power cable to my phone my phone charges so that is fine.
I have tried connecting my Sony Bravia TV to my Edge via MHL using a 'fresh HDMI cable' and it doesn't do anything.
Is the Pioneer MHL incompatible with the Edge (is it a 1st generation MHL) and the Edge can only use the current 3.0 generation OR is the Pioneer MHL compatible but mine is broken? Is the Note 4/Edge backwards compatible?
I really appreciate your help.
I have a note 4, and the appRadio 3 also.
You will require to use the Samsung MHL adapter as the phone requires 11 pin connector for the video output.
I tried many 3rd party adapter, but neither of them are stable. So, I just stick to the OEM one.
Just connects this adapter to the HDMI cable and the USB powered cable and you are good to go.
Hope that helps.
Benny
Thanks for your informative reply.
Having conducted some more research I have found the following:
The original Samsung MHL adapter for smartphones. Released in 2011 for the Samsung Galaxy S2, this adapter has a 5 pin layout. External power is required.
Click to expand...
Click to collapse
I believe the Pioneer MHL provided is Generation 1 (5Pin)
Compatibility with 2nd generation phones is possible with 5-11 pin adapter.
Click to expand...
Click to collapse
The Edge needs an 11pin, like you said and the 5pin will not work on its own and so rather than use a rubbish adapter I have ordered the below.
This is the one I use and works great. I had a Samsung one, but the way the micro USB for charging plugs into the same side as the MHL connection to the phone is awkward. Also, the USB on the back of the head unit doesn't put out enough juice to charge the phone while running GPS/streaming and the like. So with this you have a little extra length to plug into a fast charger if you want, and run the MHL cable to a convenient spot since its a LOT thinner than an HDMI cable from the back.

Thanks for the advice. My original Galaxy Note charged to 100% when under full load with the standard power from the AppRadio. However your right in saying that the new Samsung MHL adapter will ruin my set up because during installation the HDMI/USB Power are in the same 'section' of the centre console and I can't stretch the USB power cable without an extension lead.
So I will use the below that I have fitted in the centre console for power.
So although I won't know if my Edge would drain using the AppRadio power (my N7000 did not do this) this is rated @ 3.6A / 18w and it should be fine.
I have just seen on Amazon that you can now get 4.2A / 20W car chargers which is crazy!
My new Samsung MHL device will arrive sometime today (thanks to Amazon Prime). So I will let you know what happens and take a picture of my current set up.
Ps. When you say 'Fast charger'... what in car charger or power output (e.g. 3.6amps) would you consider being equivalent to our home wall plug fast charger?
Can someone help me by providing a circuit for building a charging + otg cable. I mean some sort of cable which can charge at the same time while using otg functions

Simple, buy a powered USB hub and you can use OTG plus charge at the same time. It must be a "powered" hub, not a normal hub, you may also need to get an adapter to convert regular USB to microUSB if you can't find a hub that connects to microUSB

Do a google search for:
"Powered USB hub for android"
There are many different kinds, there are some cheap ones on eBay. Make sure it is a powered hub, you won't be able to charge if it is a regular USB hub.

This is something like I'm talking about. It has a microUSB male to connect to the device and 3 normal USB female connectors to connect USB and OTG devices then an additional microUSB female to connect your charger.

Ugreen USB C hub
Hi guys,
I recently got this nice hub, so I thought I could share it with you, because it is really cheap compared to Samsungs' original parts. I got it for around 20$ from someone who was selling it new, but they go for around 25-30$.
It allows you to use DEX mode and it has all the necessary ports -> HDMI output, DC input, several USBs, some even have ethernet ports and SD card ports, but I don't care about them.

Hi there,
Yes, it has a charging port and it works.
Cheers!
This thread is pretty old, but I'm finally looking at upgrading and have some questions about the Ugreen UCB C / USB 3.1 + HDMI Adaptor.
I'm looking at the USB C - 5 Port Adaptor here:
https://www.amazon.com/UGREEN-Adapter-MacBook-Matebook-Chromebook/dp/B077FZQS95
In the notes it says that
USB C PD fast charging is only for laptops but not for phones. Phones only support normal charging.
Do NOT recommend you charge phone through USB 3.0 port as USB port only can only offer max 1.5A current and will charge your phone slowly
So I'm trying to figure out, is this like a powered USB hub that needs a PD brick to power the hub and then the hub powers the tabled (with 1.5A max), and separately powers the HDMI adaptor, UCB 3.1 devices etc., or is this a power-pass through that powers the tablet (slow) and then the tablet powers the USB devices?
In other words, is there an advantage to buying a $20-30 PD wall brick to power this hub, which the tablet doesn't support, or am I as good as I'm going to get with the original Samsung Lightning charger that came with the tablet?
Thanks,
Joe

So this is interesting in that the British version has a warning:
Please read carefully before use:
Use the original AC adapter of your device to charge your device via the USB-C Power Delivery Port on this hub
The Tab S4 (my device) original charger is NOT a 100W PD charter it is a Samsung Lightning Charger not quite QC 2.0.
Again, it isn't clear to me whether these PD powered hubs are acting as pass through for the power to the tablet/phone, and then the tablet powers the peripherals that are plugged in, or if it is a powered hub, that independently powers the peripherals and the tablet/phone - and is smart enough to power the tablet/phone with QC 2.0.
The UGREEN adaptor implies that PD is downconverted to QC 2.0, but doesn't say anything about the peripherals. This FLYLAND hub says not to use a PD charger at all.
This is So much more complicated than it should be!

I am using Tp-Links usb 3 hub, it works great. It uses external power source and its not draining too much power. Ugreen has only 10cm long cable. So pros and cons.
---------- Post added at 07:42 PM ---------- Previous post was at 07:41 PM ----------
Ugreen has good solutions also
I have used a number of different USB Type-C docking station with my Note 8 N950N and they all work with Dex Mode. It even worked using a official Lenovo ThinkPad Type-C dock station.
This update continues:
I've been using Hub Ugreen CM511 for 3 months. I connect (in addition to my laptop) monitor, speakers, mouse and keyboard, sometimes a flash drive. I'm satisfied, each input works, file transfer without lag and it doesn't heat up. Any questions?
