Charger Recognized As USB Mass Storage - HD2 Android Q&A, Help & Troubleshooting and Genera

Hey guys. I seem to be having a problem with my Android HD2. It seems that the phone recognizes certain chargers as USB. The phone allows the option to enable USB Mass Storage and turns on debugging mode.
Normally, this wouldn't be a problem since the phone still charges fine, except for the fact that it limits the incoming current to 280mA. The main charger for my HD2 is a powermat which puts out 1A but when the phone is dropped onto the mat it recognizes it as USB and limits the charging current to 280mA so it charges rather slowly. All the powermat receiver door is connected by is 2 pins. The little 3 pin interface that is underneath the battery door is where it interfaces at via thw two outer pins one for + and one for -.
I thought I had seen this issue on XDA before but for the life of me I can't find the article. I thought I remembered someone saying that you had to short something with a resistor to stop the phone from thinking the charger is USB. Does anyone know of this problem?

I have the same issue and looking for any answers. Using Android 2.3.2 on HD2.

I've had this issue with apple chargers. I am guessing here but I think it is because the iphone chargers send some sort of authentication data to the phone as a measure against unauthorized chargers. See this link for more info
http://www.ladyada.net/make/mintyboost/icharge.html

makes total sense i have heard of that its sort of a self protection

Yes, the new batch of apple chargers have some of the USB pins connected together to indicate that the device may draw more than 400mA from the charger.
It prevents my eBook from charging completely!
The only real way to fix it would be to butcher a USB cable to only connect the 2 power lines.

there are a few threads that talk about how to make some in car chargers NOT get recognised as a car kit, and that uses the same technique mentioned above, , ,namely shorting some of the pins. I assume the same principle will work here. You just need to find out which pins it is.

Fast USB Charging on O2 XDA Mini

HI Friends
Do you hv any software to carry out fast USB Charging option, to charge my XDA with same speed as done by AC Adapter...
I have seen that other WM2003 models has this option.... like in HP 6515..
Thanks
Manmohan
Interesting... I've got a desktop holder which has to modes: charge-only and normal sync/charge mode. I wonder wether charge-only mode "enables" fast charging or wether the AC adapter does something special...
If i'm not mistaken, the typical USB port outputs 5V of power at 500mAh (milliamp-hours). And in my case, my shipped charger outputs 5V at 1000mAh . using the supplied charger would charge my Magician twice as fast compared to the USB (explanation below). I think even USB2.0 ports still give out power at 500mAh.
The Magician's battery is rated at 1200mAh. Charging through the PC's USB port would take roughly 2.4 hours. Using the supplied charger, it would take 1.2 hours. Simple equation for charging is, battery rating (mAh) divided by charger rating [so that's 1200mAh/500mAh for USB]. Disregard the voltage for now unless you plan to make your own standard/portable charger. Rule of thumb, refrain charging the battery with a higher mAh rated charger.. It will damage the battery in the long run.
Hope this helps. Cheers!
Although if you could somehow control charging via software that'd be a nifty tool...
i doubt it since max current USB can provide is 500mah as any more would damage the port and probably the board.
Hello
Yup, jedhonx your right! Its the amount of power supplied! There is no way that you could use a software to charge the device in USB at faster rates.
The only way it could be thought of is like, if your device processor is running at certain spped, it consumes some power. When it runs at lower speed, it consumes lesser power and so if the software could make your processor run low or to shut down other programs maybe would show you an incresed speed of charging!

One of the following three thing WILL happen if ALL of them...
1-Fried Motherboard
2-Fried Battery
3-Fried Device
The first can happen because the USB ports will send energy to each other, the other two because voltage WILL duplicate... Think like this, when you have a device that uses "normal" batteries like a remote or a portable cd-player that uses two or more 1.5V batteries they use it because the device works with 3V (2*1.5V batteries)... Hope I made myself clear, because my english is quite rusty...

Well if you link USB ports to increase voltage it's true that it'll probably kill the mb. But linking 2 UBS connectors to increase amps is no problem and often done. You end up getting 5V 1A output. You could even link more ports to further increase the maximum supplied amps, alltough I never tested more than 3.
Linking 2 ports in a way that increases amps will NOT fry the mb, will NOT fry the battery and will NOT fry the device.
I'd say give it a try and see if it charges quicker.
Actually I think it depends on how many separate USB chips are connected to the USB ports. On one chip (or better say channel) can be more than one port be connected on the computer (like with a passive hub). In that case, connecting two USB cables in parallel doesn't change anything. Otherwise you could connect the cables in parallel and simply get more current at the same voltage (not to mix up with setting batteries in serial).
There are USB chips on the market that supply more than the specified 500mAh, but I suppose the Magician itself detects a USB connection to the computer. I remember that the first ROMs could only be loaded by USB chargers when Pin5 was connected to Ground, which was never necessary when a real USB connection was established to the computer. USB connections to the computer only use 4 Pins. This tells me that the Magician distinguishes between a connection to the charger and a connection via PC USB and limits the power drain correspondingly. If that is the case, connecting a cable with two USB ports doesn't help, it's still recognized as PC USB connection by the Magician.
it maybe OOT, but still relates. my magician can only be charged by usb cables. wont work on ac adapter. it has been going for few months and it really bugging me since it takes 4 hours to charge through usb cables.
i did try hard reset and no change .
HI Friends
I appreciate that you are trying all your mind to find the solution..
I believe that O2 provied AC Adapter wont pass additional current to screw up the battery life as it is provided by O2 Manufacturer itself. If Adapter takes 2 Hrs to completely charge the O2 Mini, then this can be done by USB cable also.
Also if you see in any other PDA running windows mobile 5 you will see an option of "fast USB Charging"..
It means that it can be done, but we need to find out how it can be done.
Thanks

Full Charge or trickle?

Is there any way to see if the unit is being fast or slow charged? It seems that the HTC charger uses an extra pin on the charger to enable fast charging and that MAY be why some aftermarket chargers (wall and car) do not seem to keep up with the battery discharge when running even if their plugged into a charger with sufficiant current capability. The HTC Wall caheger is rated as a 1 Amp charger. I have other chargers that use an external USB cable to connect, both rated as 1.5Amp (1500mA) chargers but seem to charge very slow. Soooooo I'm looking for the difference between the HTC charger and the aftemarket ones to see if I can make the ones I have work properly.
Thanks for any help

<edit> in Looking at the Mini USB spec I find 5 pins labeled 1-2-3-x-4 with 1being VCC (5v), 2 & 3 being Data + & - and 4 being Gnd. Does the Advantage use the X pin to enable fast charging? How? Does it provide a second 5v line to cause/enable the Advantage to fastcharge? I think I need to look at the wall charger mini USB pinouts.
After talking to Pocket PC Techs and looking around online, it looks like the x-pin (next to pin 4(gnd)) is shorted to pin 4 to provide the advantage with a sense line to tell it to fast charge. The also shuts off the data lines in the unit AFAICT. Still don't know what the current capability of "Fast Charge" is or how to ask the unit to query the port for status. USB ports are generaly limited to 500ma and the stock charger is 1000ma (1A) so it seems that to ensure the MAX charge, the cable connected needs to have the x pin and pin 4 shorted. This is usefull if you are NOT wanting to do a data transfer (car GPS, stand alone charging, etc).
Here is a link to the connector http://pinouts.ru/PDA/pda_miniusb_pinout.shtml
Anyone can add to this?
Joe
I just received the Lil Sync DUO Mini-5 Adapter from PPC tech and it works perfectly. I'm now getting a fast charge from my PC (no sync) and I'm able to charge my S705 bluetooth headset.
Interesting news on the pinouts. I've never heard of any utility that shows fast vs. slow charge.
I wonder if anyone has a utility that can sense a gnd on the x pin (next to gnd) of the input connector. Does anyone have a schematic of the advantage side of the input power/data connector. It would me that there might be a pullup on that line sothe unit see's it as a high untill pulled low by a ground applied tothe x pin.
here you have "hot to do it"

HD2's data cable.. is it micro USB?

I can't seem to find a usb to "whatever it is" wire selling..
is it a standard micro USB port?

yes... u r rite... itz a MICRO USB...
But it can't supply power to a USB device, so it can't be used like a PC USB port. It's only good for recharging and syncing.
so if i want to buy an additional wire, i look for a USB to MICRO USB wire right? no need to buy from HTC right?
cause i saw one usb that is smaller but it doesn't fit.. is there a MINI USB port too?
am confused

Erm yes it can,
Actually better take the device with you. Sellers here told me there is like 7 different very similar connectors. However this one should be the standard micro USB, which is supposed to be universal charger/sync cable in the future (at least in EU).
And yes, of course, there is mini USB. And there even are more versions of mini USB, for example HTC used their own.
You had better use HTC cables. HD2 is microusb, but not all microusb cables are good for HD2. Like iPhone, it takes a large charging current, and many no brand cables cannot do it. I've got a third party cable that syncs only, but if charged from the PC, the HD2 will say that the charging current is too small. Battery actually drops when I connect HD2 to PC using this cable (because my options set it that backlight is always on when HD2 is connected). Other combinations are OK:
original cable + AC plug: charging OK
original cable + PC: charging OK
third party cable + AC plug: charging OK
third party cable + PC: "insufficient charging current"
Be careful with cables- you'd be better to buy the genuine HTC version.
Many USB/MicroUSB cables are for charging only, and don't have the data pins connected. Thats OK if you just want to charge it while you are away from your main PC or power supply.
You can also buy a miniUSB/MicroUSB adapter for charging using and older miniSUB charger, but again these don't have the data pins connected.
I bought a number of 3rd party USB to microUSB cables a month ago for sync and charging (office, PC, bedside charging), so far so good... no issues (maybe I'm lucky). The OmniaII uses the same connector, so I'm using the HTC car charger to charge both.
I bought Nokia's cable (for E71,N97,etc.) and it work just fine with charging from laptop. much cheaper than HTC in here.
if you are going for the cheapo option...

charger from iPhone
The iPhone charger coud be used for charging HD2. Just plug the microUSB cord instead of iPhones and ... voila. The same outputs
N86-8megapixel cable doesnt work..
So I managed to leave my HTC cable at work (2 days after getting the Telstra HD2 in OZ) and now I am on 4-5 days leave from work and really want to tinker with my phone. I think I may end up having to go back to work to collect the HTC cable - as below... challenge to get non-HTC cable to work.
I found that my wife's N86-8megapixel nokia has a similar micro-usb cable.
When connected to the PC the phone starts charging and the PC does the "doo-doop" sound a "appears" to connect to the phone, but active sync cannot detect the phone \ sync.
I see others have had success with nokia cables - I am wondering if there is something wierd going on.

Car Charger?

Does anyone have a confirmed working car charger for this phone?
My motorola car charger that I used for my GNex and GS3 isn't fully compatible with the G2. I get a message saying "slow charging" when I plug it in.
What do you guys use to achieve full charging speeds?
I realize there's a Q&A forum, but since this is directly related to accessories, I wasn't sure if it was better suited for this forum.
Nobody has a working car charger?
Both of these work for me.

The powergen dual port works great. It has two 2.1amp USB ports, one that works with Android, and the other with Apple products (when using a data cable --> detecting USB vs AC charge mode). I have custom USB cables where I shorted the data pins so I always pull at AC charge rates regardless of the port type. In any event, this charger should provide you with the same capability as the OEM wall charger.
I have a 2amp car charger and it works fine, no message about slow charging.
the issue im runnin into is find a usb cable that enables fast charging
i have a dual usb car charger that put out 2amps per usb but cant.find an aftermarket usb to micro that can support more amps (fast chargin)
the oem lg g2 cable works...as well as the nexus 7 cable
i got this cable but doesnt charge more than 1amp

To short the data pins, I actually cut a USB cable, stripped back the insulator, re-soldered the +5V and ground wires, soldered together the data pins on the microUSB side of the cable, and stagger cut the data wires on the other side. Prior to the re-soldering, I slipped some shrink tubing on one end of the cable to re-insulate everything. Not for the faint of heart.
Background for those that don't know... Typically, Android phones look for little to no resistance on the data pins to detect a high current charger. Any other load triggers USB mode since most PC's are only designed to supply 500mA via USB. I assume this is a safety issue to prevent overdrawing a PC's port. Apple operates differently. They look for some nominal resistance as USB and switch to fast charge under open or some higher resistance. Most chargers >500mA are designed for the iPhone market unless they explicitly state other compatibility. Therefore, the data pins are floating. Any charger can be used at its max rating if you trick the Android phone with the homemade cable described above. Of course, then it becomes a power-only cable, useless for data. Clearly, OEM chargers for Android phones short the data pins internally so your OEM cable can be used with a wall charger (fast) or with your PC for data connections and nominal (slow) charging.
So the powergen mentioned above has two 2.1A ports, one labeled NA (non-apple) and A (apple) so you don't need to worry about mix-n-match devices and cables. Any USB cable will fast charge on the appropriate port. With my homemade cable above, my Galaxy Nexus will fast charge on either port.
Fast forward to the G2... Just got it yesterday and while in the car, I noticed my homemade cable only permitted SLOW charge on either port. Huh. Kinda a head scratcher. I ran in the house and got the OEM LG cable and both ports worked with FAST charge. So I tried one more thing, I grabbed a regular USB cable and observed the following: the phone went into FAST charge on the apple port and SLOW charge on the non-apple port. I can only assume that LG is detecting fast charge in a different way. The fact that a standard USB cable doesn't work with the data pins shorted at the charger but the OEM cable does makes me think there is something about LG's cable that allows it to pull max power from the charger. FYI, I plugged the OEM LG cable into a 850mA Motorola AC charger and it registered as SLOW charge.

I have pretty much the same thing, had a cable that would only do slow charge, so I stripped the wires back, and on the micro usb side I cut the green and white(data) and twisted them together. Now its fast charge no matter what charger I plug this cable into.... not sure why urs isn't....

I tried the USB plug in my car (Scion 2012) and two different Belkin cigarette/USB chargers today. The USB and one of the Belkins gave slow charging. The other Belkin did not -- worked fine. They were supposed to be identical, but I had suspected one was a fake. Guess I was right.
I just use the usb cable that came with their phone and plug it into my auto usb or the car's 110 outlet.

No wireless charging?

Since it has a titanium body, it looks like Wireless charging will be missed
Or will it?
It look like it has a charging pad, BUT it looks like it will a magnetic connector will allow Qi-ish like charging where you lay it down without having to connect a usb cable, but the back docking pins will charge the phone. When charged you just pick it up and go without having to disconnect anything, WHICH I FREAKING LOVE ABOUT MY QI wireless charging right now with my Nexus 6.
The back is ceramic, not titanium. So it could work, and does work, but you need to connect with their pins for the phone to recognize the pad. It's wireless but I think without the pins it doesn't work. We will have to wait and see..

Just buy a cheap $15 Bluetooth aux. No more wires in my car, besides the charger if I need it.
You know, The phone supports Wireless USB. How exactly do you suppose they accomplish that? Its already been stated by Andy that the two connection points are magnetic for aligning accessories. Now, I don't think anyone knows for SURE how this phone's tech actually works yet. Since Andy went on record to say this tech will be open source, who is to say this wireless communication couldn't support Qi charging with a software update. It's entirely possible that this phone supports that out of the box. Really I am not confident that this could be answered with a " yes it does" or "no it does not" quite yet. Unless I am uninformed? can anyone else chime in?
EDIT** pins do provide power infact too.
When the phone website first launched there was an accessory for a wireless charging dock that said coming soon..... It's not there anymore. I thought it was supposed to transmit power thru the connector pins. But maybe the pins only transfer power from phone to accessory not accessory to phone.

Your right.... It is still there....I overlooked it. Well I'm not really sure why every review says there's no wireless charging. Assuming this dock actually comes out.... It is charging without a cord/wire... Which is essentially wireless charging. It's just not qi wireless charging technology.... It could basically be described as proprietary wireless charging.

It will be interesting to see what they do with the adapters. If they do that, I hope it includes a 3.5mm jack. For a lot of people that's still the only way they have to tap into their car audio system.
I am pretty sure the 2 pins are just for power, and any wireless bit is through the 60hz system which is more than likely data only.
So no Wireless charging parse', but with the dock, it has fancy pin charging lol.
I do also look forward to seeing what else they use that expansion ability for. Heck If they wanted to add a headphone port to the phone how easy would it be to just build a slim plate that attached to it that barely is thicker than the port itself, but is a bit wider to include a nice DAC and AMP? Doesn't take up the USB port for charging and could have really good audio to boot. The possibilities are endless and unlike some of the other modular designs, this one seems to make good sense and not be an eyesore when not in use.
Wireless data transfer and wireless charging are not even remotely the same thing. Data transfer is radio waves with a transmitter and receiver. Qi charging is electromagnetic induction (a magnetic field around a coil of wire will induce a voltage in the wire).
