Hi all,
I'm looking for an Android tablet that has a separate (DC-in) charging port. Or maybe two independent USB ports, one for OTG and one for charging.
I've seen devices with round DC-in jack before but don't remember brands or models. Tablet-specs databases usually don't go into much detail regarding charging ports.
Any advice?
TIA

A similar question has been asked on modaco but I don't think a solution was found. Therefore I am going to ask if this would work here.
Is it possible to connect a micro usb (male) to mini usb (female) adapter up to this thing (HTC 4 in 1 adapter: I can't post link because I am a new user but just search it on youtube). This would connect to the tg01 micro usb and provide a 3.5 mm audio out in addition to a mini usb connection where one could potentially hook up a charger. I was thinking of testing this out as it would cost about 10-15 dollars but I do not want to damage my phone in the process. I have no electrical engineering knowledge but maybe someone else can explain if this would work before I order anything.
On a side note: I order samsung WEP870 bluetooth headphones on sale as an alternative to this. Note sure how sound quality is but I will try answer any questions you guys might have.
Any input is welcome.

I was heavily involved in the discussion running on MoDaCo you refered to; unfortunately there has been no breakthrough on this issue to date.
I did look into the the HTC adapter you mention, but it actually uses the proprietary HTC ExtUSB plug on the input end (connecting to the phone) and NOT a normal mini-USB. The ExtUSB has 11 pins which include a discrete audio output (being used to feed the 3.5mm jack socket) and also hard-wired power (used to accept the charger input).
In the case of the TG01 uUSB socket, it is too 'intelligent' for its own good. Every function, charging, audio out, USB data transfer, etc., is under procesor control. Different functions are triggered by the device 'seeing' a certain resistance across the sense pin and ground; depending on this the processor then configures the use of the socket pins accordingly.
I am after what you are trying to achieve also; there is a chip supposedly available which is intended to fulfil exactly this functionality, but I've been unable to find any devices on the market which use it and attempts to contact the manufacturer with a view to getting a few samples to try and build an interface have so far been unsuccessful.
I've attached a couple of documents which explain the uUSB Charger Adapter and also the chip spec sheet for reference.

If anyone else knows anything to help move this one forward, will be much appreciated !
Thanks for the nice explanation,
Hopefully one day there will be an adapter that can make this possible.
Hi all,
Has anybody got any of these? I have my old diamond 2 htc car charger and would like to be able to use it on the desire via an adapter. I understand most adapters only support charging?
Please post your experiences with any you have tried.
Thank you
The adapters shouldn't be a problem. They should have a full set of pins. Some cables only have the pins that are used for power.
BTW - someone is likely to ask why you are syncing your handset with your car cigarette lighter

i've bought some mini to micro usb adapters and they are great for charnging and sync as well. they are made in germany, delock is the manufacturer.
Have a look at my post in, "Not a Standard Micro USB power cable"
There is an adapter available from CPC in Preston (Mail order available, but don't know how much they charge) and also a couple of USB -> Micro USB leads available from them.
Also available, from Maplin is a 'micro' cigarette lighter to USB Adaptor to plug into your car which is quite a bit smaller and sleeker-looking than the one I currently use. For £5.99 it seems a reasonable deal.

i sincerely had to laugh at that comment
I bought a couple of cheap generic USB cables, one a retractable micro USB job and the other a standard USB that splits to both a mini and micro USB at the other end.
Both cables charge my phone just fine, but the phone doesn't register either cable as a data connection and no notification comes up.
Is the micro USB cable that comes with the phone industry standard, and if so does this mean that my generic cables are likely to be just off spec enough in some way that the phone doesn't register them?
Strange thing is that the mini USB end of the split cable seem to work on other things like cameras and other phones. I'm confuzzled.
when plugging in cable did you activate usb mount in the notification bar
i bought a mini to micro converter as I still have quite a few devices that need mini and thought I could save on convenience by just carrying round the adapter and plugging into existing computer cables and chargers I have around the house, car and work - Same thing with that power only, no data.
Got it from ebay some of the listings on there state "power only", still dont understand why, it cant be much more expensive to wire all 4 pins. As micro is becoming the standard.....

That's the problem, I plug the cable into the N1, but don't get a notification, no tone, nothing to suggest that the phone sees the cable as a data cable at all.
I'm guessing that if the phone doesn't think it is a data cable there is no way to persuade it otherwise.
There's essentially 2 types of cables: Charge-only or Sync & Charge. This is true for the adapters as well.
It seems you folks mistakenly bought the Charge-only cable/adapter.
After some research, I found this cable (it's blackberry branded, but works 100% with my N1 for Sync and Charge):
http://www.amazon.com/gp/product/B001UC9NOQ/ref=oss_product
It's cheap ($3 shipped), it's made by a trusted brand (Blackberry) and the actual cable is rather thickly insulated so it's durable too.
Read the user reviews, especially the guy with the high helpful votes count, for more details about charge-only and sync-n-charge cables.
Just tried both cables on a Nokia E623, and they both worked fine first time, charging and data.
Now it' looking like there is something slightly odd (or perfectly on spec) about the female Micro USB plug on the N1. Perhaps they are just made to only accept male plugs that exactly meet standard specs, and if a plug is out slightly in say it's contact positions or sizes the N1 won't detect it.
Anyone got any ideas?
Hi guys,
I'm trying to figure out how many products do actually use the 11 pin microUSB connector. I know the S4 and the Note 2 do, and I guess I'm pretty safe asuming the Note 3 and S5 also have it. Do you guys know any other device having 11pin microUSB connectors?
For the rest, the advantage of this connector is the capability of having an HDMI connection, with space for additional (and simultaneous) USB connections. That means, with the proper adapter/dock, you get to have a full fledged "computer", with monitor, USB mouse and keyboard, and you can even plug external drives, all at the same time.
The ports with 5 pins on the other hand don't seem to be able, so you either have HDMI or USB, but not both at the same time.
So yeah, any other model? I'm seeing now on the search suggestions it seems the HTC Hero also has something like that...Is there any list or compilation somewhere?
Hello All,
I'm a new owner of a Galaxy S6 Edge, coming from a S4.
I had a Samsung multimedia dock for my S4, that had 3 USB ports, a HDMI Out port and a 3.5mm audio Out port. I purchased a wireless keyboard / track pad and plugged it into one of the USB ports on the dock to make typing texts & navigating the phone easier while at my desk.
Unfortunately, the male micro-USB plug on the Samsung multimedia dock does not fit the micro-USB port on my S6, rendering my wireless USB keyboard useless.
I've looked all over the internet and can't seem to find a similar docking station for the S6. Does anyone know of a docking station that has USB ports that will work with my USB wireless dongle & keyboard?
Much appreciated!
Hi,
Thanks for your report. It seems strange to me that the S6 micro USB port is different, should be the same old 11 pin that the Samsung used. Stupid question, but did you try inserting it the other way around, with the phone back facing you?
For your exact problem, with the keyboard, I assume the old USB On The Go adapter will work on S6, same as it does on S4, S3, Note2, etc. It's this one: http://www.samsung.com/us/mobile/cell-phones-accessories/ET-R205UBEGSTA .
There's also a HDMI adapter, http://www.samsung.com/de/consumer/mobile-devices/accessories/connectivity/EE-HN910FWEGWW. Maybe those 2 can be combined, instead of using the dock.

Thanks for the reply!
Way ahead of ya on making sure the micro-USB plug on the docking station is facing the right direction. I tried docking it backwards and the plug n' port absolutely do not fit that way. It's facing the right direction, just that the port on the S6 is not able to accept the plug on the docking station....despite both being Micro-USB. I did notice, however, that the plug on the docking station had two small grooves indented in it, that looked different than any other standard micro-USB cable plug. It could be that those indentions made the device proprietary to the Samsung range of phones that released during the S3 / S4 years (including the Note 2 & 3). If you look at the compatibility of that docking station on Samsung's website, you'll notice that only the S3, S4, Note 2 & Note 3 come up.
I suppose the USB dongle you linked could work, but reading the device laying down flat, while trying to type on the keyboard might be problematic. You'd think that someone would make a universal micro-USB docking station with USB ports...but I haven't been able to find it.
I'm pretty sure the S6 no longer supports MHL which probably explains why the dock doesn't work either.
You can still go USB OTG, which should let you use your keyboard and trackpad mouse devices.

Interesting.....so are you saying that the micro-USB male plug on the Samsung docking station also had MHL connectivity integrated in it, which is why it's form factor is slightly different than a standard micro-USB plug?
The only times I've ever seen a MHL port on mobile devices was as a separate, similar looking, but different port than the micro-USB port.
I supposed all the wireless mirroring tech out now makes including hardware mirroring functionality not needed.

That's correct, it has to since it offers an HDMI out on the dock.

You're also probably right in your assumption that MHL isn't really needed anymore due to the widespread wireless screen mirroring technologies.
