I'm going to look stupid here, but ...
Received HD today in USA and wanted to charge it. But I do not know HOW ???!!!!
I plugged USB cord into HD itself, and other end - into AC Adapter.
Now AC Adapter looks strange to me ... the pins are INSIDE of adapter, so I cannot plug it into the wall electric outlet !
I do not have any plug to put it into AC Adapter! It suppose to come with one ?
What do I do now ?

Did you plug the power-pin adapter into the AC adapter? You have to put the wall-adapter onto the AC charger itself, then connect the usb cord to the ac adapter, then plug in the phone...

I just received mine today too. The piece that goes into the wall plugs into to piece that you plug the USB cable into. Now the plug that comes with the HD is for the UK or maybe Europe in general I am not sure. Mine came with an adapter that plugs into the two round pins that come standard with the HD. I hope that is clear. In other words if you did not get an adapter that looks like a regular two bladed electrical plug then you will have to get one or you will have to plug it into your computer for now.

That power-pin adapter which I suppose to plug into the wall AND into AC adapter ... it suppose to come with the package ?
Where can I buy USA plug that I can insert into wall outlet (one end) and other end goes to HTC HD AC Adapter ?

early on, some owners noted that the HD wouldn't charge that way, even though the display said it was charging.
Don't recall if we ever got to the bottom of if it was via direct USB socket on the PC, or via a USB hub - but basically the phone wasn't getting the full (5.5v?) voltage from the PC.
To charge the HD from the mains, you need 3 pieces of kit, which should all have come in the box.
1) the USB lead
2) a small box sized unit, about 5cm by 3cm by 3cm. It has a USB socket on one end, and the other end has 2 prongs inside a cut out section.
3) the plug bit. This should look like a regular plug, but on the back (the other side to the prongs), you have just a small box, with 2 holes in it. These holes align with the 2 prongs on item 2 above.
Slide 3 into 2, and 1 into 2 too
Depending on where the HD was sourced from, them item 3 may have 3 prongs (if its UK spec) - which obviously won't fit into a US socket.
The writing on item 2 seems to indicate that it will take an inout voltage of 100 - 240V - 0.2A 50-60Hz.
No idea if this means it will work with US mains voltage, sorry.

Mine does, I've never charged it off the mains
Having said that, a lot of motherboards don't allow charging off them, for whatever reason. Maybe they shut down power if there's no data connection after a while, or don't provide enough current etc etc.
could be
Mine seems to charge ok off the (powered) USB hub - but some owners have reported that theirs didn't
I'm just paranoid about batteries (probably overly so!), and like to make sure that the very first charge is a blinking good one
Thats not an issue with lithium ion or lithium polymer batteries, they dont have a memory effect, the first change is not important.

It seems that I'm missing piece# 3 - the plug. Is this some specific plug for HTC HD, or generic ?
If it is special for HTC HD - where can I find it ?
I recommend purchasing the TC P300 International Travel Charger Kit. It's available on Expansys or HTC's accessory store. It's the highest quality kit available and the TC P300 is the actual charge provided with the Touch HD. You only get the EU or UK plug. I could not find a kit of just plugs. A cheaper alternative is the HTC TC P200 International Travel Charger. Also, available from HTC accessory store or Expansys.
This is driving me nuts. Go to an electronics store Best Buy, Future Shop, Circuit City, and take your charger with you, they will hook you up. You might even be able to get a universal charger, I think the ones for Iphones have a USB attachment on them.
I have plenty of USB chargers, so I don't mind UK plug. You may buy a new 1000mAh USB charger here: http://www.dealextreme.com/details.dx/sku.25 just for $5.25 or just adapter for $3.46 http://www.dealextreme.com/details.dx/sku.17840
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.

Does anyone know if you can use the g1 car charger with the Samsung Vibrant? I read that the Samsung vibrant uses mini usb but of course that does not mean it will work properly. Thanks
No, the Vibrant is micro usb, not mini.

Yeah, like it was said, micro usb, but on ebay you can find mini to micro usb converters... I bought 2 for .99 cent a piece shipped and they even transmit data, sadly one has some loose connections but the seller refunded me right away for it.
Other than that I am not sure it's the most efficient (I haven't looked at what the g1 power supply sends amp wise, nor the max the vibrant can take) but it would work, as long as you get the right male end (again, micro usb)
Also, there is a accessories forum that this would have been better suited for.
EDIT: Sorry, I may have spoke too soon. If it was an HTC charger it might not work since only one corner of the male end is cut and the other is straight, that is their proprietary male connector that has extra pins and will not fit in a female mini usb port. Now if it was an aftermarket that was a true mini usb, then you can get a converter... Otherwise you can just get a car charger that has the standard female USB A port and plug in any USB A to Micro cable... Point is, if it is USB you are on the right track.
Looks like the streak might have usb host... if you look in the sdcard settings it has the option to unmount ums (usb mass storage) devices and the option to format them.
Im on the 8105 2.1 o2 rom on a us att dell streak.
Ill make a cable soon to test but was wondering if anyone else tried th already

If the option can be found in 1.6, I may already have the hardware to test it.
This would be a beautiful thing!
I just so happened to have the correct hardware on hand to try this so I gave it a go, looks like it does! I'm actually typing this message with a USB keyboard- I can't get it to mount a USB drive yet, but I intend to brush up on my Linux commands and syntax tomorrow and try again- if I can get it to mount external storage, all of my dreams have officially come true (minus the Froyo, that is).
Edit: I'm on the MoDaCo custom ROM r2, 2.1 build 8105, for those interested.

Hey there, real interested in what you did to mod your cable to handle this. Was it a matter of tying the OTG pin to ground?
Did the streak supply power over usb? Many android devices cant, but I believe given the right cable mod the streak can.
I didn't have to do any mods on mine, I have the home dock (which converts the Streak's port to miniUSB) and a dongle that has male miniUSB on one end and female standard USB on the other. Streak on the dock, dongle in the back of the dock, and keyboard into the dongle.
I don't know if it supplied power or not, what would be the best way to check? Multimeter across the power/gnd should give 5V regardless of if it's powered, do I need to check the amperage as well? I was thinking I might just try firing up the ol' G1 and plugging it in, to see if it charges.
Sent from my Dell Streak using XDA App
A good test would be to not have the dock plugged in to any power source. Dock your Streak, then use your adaptor with USB keyboard. Does it work? if so, the power is being supplied by the Streak.
If not, it doesn't prove that there is no way to get powered USB host out of the Streak, it would just show that it may require different connections (a modded cable or dock).
Then yes, it supplies power, my dock was unplugged the whole time. Rejoice! I foresee emulators with a USB gamepad in my near future...
Sent from my Dell Streak using XDA App
That's great to hear! Game controller for EMU's is what I'm looking to do with it as well
Funny though, I tried the same with a gender changer a week or so ago and it didn't work for me. I think the difference must be that the cable you're plugging in to the dock must ground the OTG pin.
Unfortunately that probably means I'd either have to get a dock, or dissect and solder my USB cable to get the same.
Glad to see it works as i suspected. now all we need is some to make it mirror the display over the hdmi out

Ah, I wondered what that meant. I have the home dock and saw Win7 did something funny... it's all a bit beyond my abilities so I look forward to someone doing interesting things with it

Unfortunately I don't think a female to female adaptor alone will do the trick with the Streak USB Cable. I have one here, and it's not working.
I believe the reason is the USB OTG pin needs to be grounded to identify that we are in USB OTG mode (pin 4 as identified here http://en.wikipedia.org/wiki/PDMI).
I think the reason it's working with the dock for that person is because the dock exposes that pin at the mini B port and the cable adaptor he's using is an OTG cable that grounds the pin.
I haven't tried modding my cable for this yet, but will soon. My soldering iron is in storage right now unfortunately.
Ok; I understand that we have to connect OTG pin (no 4 on PDMI) to GND (no 2 on PDMI)
Is that correct ?
Is there a way to do it on the other end (not the PDMI side but USB side) ?
Because I don't want to break my only Dell Streak data cable...
Unfortunately, no. only 4 wires run through the cable and are exposed at the other end. You would need a 5th (the USB ID, aka OTG lead).
So I just finished creating my own modded cable and it is working great.
I've attached pictures of the build here. I found that this only works in Android 2.1 (8150 build for me, may work with other 2.1 builds). 1.6 seems like it doesn't have the drivers for this.
DISCLAIMER: If you try to duplicate what I did here, you're taking the risk of damaging your cable beyond repair, and if you do something incorrectly and plug the cable in to your Streak, there is a definite possibility you will damage your streak permanently. So anything you do, do so carefully and at your own risk!
I will say this; this cable is HARD to de-shield! It has metal shield all around the parts we need to get to, and I had to cut with metal clippers and desolder parts of it to get the shielding off. Not pretty, and pretty risky for damaging the cable. I would advise you buy an extra cable before trying this. I didn't have an extra, but I was really risking not being able to charge my device or something if I broke my cable.
After removing the shielding you can see that there is a small PCB with traces marked 1 3 on the left, and then 2 5 on the right. These correspond to the PDMI specification at http://en.wikipedia.org/wiki/PDMI .
For my build, I chose to solder a switch to bridge the OTG pin 4 to GND pin 2. This way, my cable can still be used as a normal USB cable as well. In one image I have flipped the opened PDMI connector over and you can see an orange wire I have soldered on to pin4. (One side of the PDMI connector has ODD pins, like 1,3,5,7... the other side has EVEN 2,4,6,8...). Pin 2 is the first pin on the right on the EVEN side, and pin 4 is the second.
As was stated in earlier posts, you can use a female to female gender changer for the other end of the USB cable, rather than soldering on your own connector or something.
Note that having the cable in OTG mode when plugging your streak in to your computer or power adapter over USB could damage something because OTG mode will start outputting power over the same pins that it's usually inputting from!!!
0TheRain0,
This is great !
Thanks for sharing your findings.
I sent you a PM; please check it when you have time...
When I built my Dell Streak Mini USB adapter, I brought out PDMI pin 4 to the OTG pin on the Mini USB.
I tried it with 2 different cheap Mini USB to Standard USB ("A") female adapters, and tried several devices including a Apple Mini Keyboard/Hub, and USB Flash drives.
I also tried the same components on the Dell Home Dock.
They did not work, but I suspect that the Mini USB to Standard USB female adapters do not short the OTG pin to ground.
What we need is some that do. Then it would be plug and play at least for dock owners.
Edit:
These claim to enable USB host mode when Connected to a N800:
http://www.electronicproductonline.com/catalog/product_info.php?products_id=2043
Therefore Should require no modification to use with the dock, as long as the dock brings out pin 4, which as far as I remember, my testing said it did.
This thread is currently of great interest. Should it, in theory, be possible to hook up my Canon digi SLRs as mass storage devices then?
Sometimes being able to get the image onto a bigger screen has it's benefits. The Streak's screen is actually very well calibrated as well, compared to my hardware calibrated monitor!
In the ideal world i'd be able to tether and shoot using the streak (like I can with my laptop) but I'm realistic and know that's not likely to happen!
What I DON'T get is why Dell have put in USB host functionality without implementing it in the lead?
Well, I was going to hold off on cutting up a cable to try something, but I just had a cable go through the washer and dryer... and it was looking pretty bad and actually cut through the jacket and shielding on the wire... so I cut off the PDMI lead and about 3" of cable (right before the break).
Inside the jacket are 4 wires. Black, White, Green, Red. Obviously they correspond to the USB 2.0 spec... so I guess in some way, VDC, Ground, Data+, Data-... but no OTG wire.
Would anyone that opened up the connector know how these wire colors correspond?
What I really want is for my 80GB iPod to have it's music available to the Streak in my car, so here's what I was planning:
1) Cut up the Dell PDMI cable (done).
2) Cut up an old iPod to Firewire cable I have laying around
3) Splice VDC+ and Ground on the iPod and PDMI to the corresponding VDC+/Ground USB end of the original Dell Cable. This will plug into a 12V->USB Adapter (probably the Dell one) to power and charge both devices.
4) Splice the corresponding PDMI and iPod data transfer wires.
5) Ground OTG on Streak side and add a micro switch, like TheRain did...
I can then wrap this up in some custom cable thing shround thing that I'll figure out.
Little bit of research led me to the micro-AB receptacle that basically determines if a device is acting as a host or slave. So, I would say the preferred way to do this, instead of wiring in a switch, would be to find a receptacle and hack into it... so here's one you can get cheap:
http://www.retractablecables.com/US...ro_AB_Female_Adapter_for_USB_OTG_Devices.html
This should be able to wire up something that basically puts the device into OTG mode when you connect a micro-A cable to the device, and a slave device when you connect a micro-B cable.
So solder/wire that up.. connect the Streak with a micro-A cable to a powered USB hub, connect the peripherals to the hub, and you should be good to go without a micro switch.
On an edit note, I also found a bare micro-AB female that you can buy... but it's more expensive than the previous adapter, so uh I guess it depends on how much time you want to spend tearing the adapter apart.

Hi,
I made my own usb otg adapter from a plain usb a to micro b adapter. You have to connect pin 4 /which is not connected/ to ground to fire up host mode.
Edit: It is not easy to dismantle a usb connector or adapter and it requires soldering. So I guess anybody with the necessary skills will find the pin on his own. I will not post photos because my solution is far from being pretty.
For everybody else: the nokia USB OTG cable is wired the same way so it is very likely that it will work. (on Hungarian forums I saw references that it works, but I can not guaratee it.)
Tommorow I will go buy one and report.
USB Host mode will allow to connect USB pendrive, mouse, keyboard etc. to the SGS II.

this is very useful for people like me who knows how to solder things, but for the people who have absolutly no Idea what you are talking about, you should add more details/pictures to the OP so the people who doesen't know much about electronics know what you are talking about, and what benefits it brings for them.
I myself will probably make one or more, so I don't have to always take my USB OTG with me all the time.

OTG Cable USB (B) to Micro USB (A) Powered with AAA batteries
As one knows, Samsung has promised a HMI Cable
You noticed it is not only a cable but a box out of which you may plug in an extra power supply.
The obvious reason is if the passive monitor does not furnish 5V, the phone will rapidly be out of power.
Now you know that to obtain video rather than anything less, Pin 4 (sense) and 5 (Ground) of micro USB (male A) must be connected with a 365K resistance.
I suppose the dock Samsung is selling for I9100 (yes, I have it) is grounded at 1000K as it provides audio with remote, and yes, the dock provides power supply via extra micro USB as well.
I come to my point: If I want to access any USB data On the Go, I need a cable OTG with 2 ports: USB 2.0/3.0 (female, B sided) to a micro USB (male, A sided, grounded but with no resistance = 0K). Many of them exist on the market out there.
But it is quite impossible to use because of lack of power supply in the passive device (let’s say a handy 1T HDD usually powered via Host connexion !
Would it be possible to insert some sort of receptacle for AAA battery in the middle of such a cable to provide for power while you are for a long time out of access to an electric plug ? Does such a cable exist somewhere to buy ? What would be the sheme to mount this ? HELP !
Instead of shorting pin 4 and 5 from within the cable head, would it also be viable to short them from within the device itself? Say if I disassembled the phone to access the back of the female usb micro connector and soldered the pins. Would there be any damage caused if the permanently shorted pins 4 and 5 (within the device) is connected to a charging adapter/PC?
