Hi,
Just purchased a cradle for the universal which has a USB and an AC adapter connection.
The USB works fine for charging the Universal.
The AC Adapter connection on the other hand doesn't charge the PDA at all.
I thought I remember reading something concerning a fix for this but can't seem to find the post for it.
Any body got the solution for it or do I have a faulty cradle?
Thanks.
I would change usb cable

Did you ever find a solution to this?, I have the desktop charger jobby. The grey one that looks like a docking station. It has an ac adapter and a usb out on it .. but like you the charger doesn't seem to work.
p.s its the one with the stylus that stands up straight at the back.
Nope.....
Never found a solution for it.

Does your original jasjar/xda exec charger work? mine doesn't.. only my 5v dc 550ma motorola charger works ... oh and the usb direct cable works..
Does you pda charge while sat in the cradle with just the usb attached?
Here's what I have working:
FYI, I have the Qtek 9000.
Original Power Charger - working
Aftermarket Car Adapter charger from Proclip - working
Aftermarket Desktop Charger (AC powered) - NOT working
Aftermarket Desktop USB plug - working
Aftermarket USB cables - working (at least the ones I've tried = 3)
Joe,
I remember reading that you should be careful of what you plug in to power up your HTC-Universal because the voltage needs to be regulated.
Also, don't even go buy those Alkaline battery powered travel charger - they don't work. I even tried with a 9V Altoid Tin Battery Charger (with the required 5V USB regulator) and it didn't work.
I just gave up and carry 2 batteries with me. Planning on getting a bigger battery later on.
Hope that helps.

Thanks for the reply,
Just checked on the web and the moto charger is regulated so it should be fine to use, I was thinking that my original charger may be buggered but because my new desktop charger doesn't work either I don't know what it could be. I'll need to try my cradle with just the usb attached tonight and see if it charges... if it does thats ok .. I can live with that.
My Cradle has a built in usb cable for the pc and a separate dc in socket for the wall adapter so unless it switches between the two i'm thinking that maybe the pins for charging are hardwired to the wall adapter and the data to the pc so it will only charge from the wall and not from the pc..
Maybe I shouldn't have bought such a cheap one
Joe,
I believe I might have the same cradle as you do.
I've open up the cradle to see how the connection is soldered and the points for the ground and powered seemed soldered into the USB port correctly.
I do remember reading something concerning the pins for the USB are wired differently (last 2 pins are shorted - on the Universal-wiki I think) for powered USB charge. Maybe that's why the cradle AC charger doesn't work while the USB cable works.
FYI, I've tried putting both the AC and the USB and you'll find that having the AC in is useless....you're just wasting electricity cos the PDA is still being charged by the cable (just turn off you PC and you'll find that the PDA is not charging).
Does your cradle have the annoying blue LED?
I think all aftermarket cradles are created equal = "CRAP"
If somebody out there have a cradle that have AC that works, please post where you bought it so that others will know which one to get.

Sounds like I have the same cradle as you fella , I've tried the usb on its own and it seems to charge ok .. I tested it by putting a movie on and leaving it plugged in, started at 67% its now 77% so its charging through the usb.. dam it .. I could probably send the cradle back since I wanted it mainly for AC charging. Wish there was another one I could get that worked!
Thinking of getting this one instead:

What dya think?
joe....
According to this guy on this thread:
http://forum.xda-developers.com/showthread.php?p=1097137&posted=1#post1097137
his is working just fine.
If you can return it for another one, maybe you'll get one that's working properly.
i'm thinking maybe we have pda's from the same manufacture date.. and the hardware revisions are different and thats why our desktop chargers dont work, surely its not coincidence that both of ours dont work?
And if thats the case getting another of the same won't do much good.. theres just no way to be sure about any of this, think I may just send it back and try a different one entirely
Joe,
Good luck!
Hi all,
I am trying to find a spare USB cable for my TP2 and not having luck locating one here in Jakarta. I want one to leave plugged into the PC for syncing and the original one I will use with the charger each night.
Anyone know if a standard USB cable will work with the TP2. I am concerned that the 2 row of connections gets shorted on the plug even though it appears to plug in. I have tested it with power on so no idea of it actually works or not. Don't want to risk damage to my brand new TP2.
Cheers,
Dave...
Don't worry, a standard cable will work! I have used one for the past 3 years with my tytn ii and have been using them with my TP2. It was designed to be compatible as far as I'm aware!
As you can see if you look when offering the cable to the hole it fills the whole thing and fits snug and theres a gap of .5mm or so between the underside of the plastic bit in the phone to the metal of the cable or plug.
I hope that made sence!
The 5 connections on the underside are for audio, just incase you where wondering!

Is anyone aware or the physical way to fool the desire to go into car dock mode either by rewiring a usb cable, or does it use the same magnetic sensor as the nexus, I currently use a boadit iPhone cradle that fits perfect and i have a charger mini usb cramped and srewed into the bottom, I would like to be just be able to drop it in and it go into the Navigator app and switch on bluetooth automaticly and kill both when i remove it ..
thanks

The droid/milestone used magnets to detect the dock, but the google car dock uses bluetooth and doesn't even use the usb cable (it uses the gold 3 bits on the bottom of the phone). I too wished you could do the same, but my brodit holder fit the phone so badly, I've decided to shell out and try the original car dock - just waiting for it to come.
Thanks for the reply, so the million dollar question is how does the desire's dock sense when its dropped in the cradle, any ideas people ? I read somewhere forgot now doh !! that it might be a case of grounding one of the data lines in the usb cable, can anyone confirm this ?
I'd like to know this too.. Dockmode/Cardockmode
Look at this thread - probably the id pin, but i need someone with the same charger and a multimeter to check some things
I have 2 chargers (work & home) that I use that plug directly into the wall, the one at home brings up Navigator where the one at work doesn't, so it must have to do with the pins in the USB connector.
Can you do some measurements with a multimeter on that charger that opens the navigator???
oh this sounds like what we wanna hear, my betting is one of the usb data lines gets grounded as ive mentioned before !!! plz test to see if more than one of the pins in the usb plu is being grounded .... pretty plz !! heh
Hey Guys,
yes it looks like the Desire can be fooled into thinking its connected to a car dock, my car charger seems to do it when the usb is not properly inserted.
I suspect HTC might release a car dock for the Desire. If not some one should really monopolise on the fact that this can be done.
I will be experimenting with it soon but currently have way to much uni work to finish for the end of the month
Ok went into the workshop and stripped the desire usb lead, I tried every combo of pulling the data lines to ground even both together, the installed navigator.apk didnt kick in , but looking at a reatime system dump i could see usbconnected and type(0) , type (1), type(2) had been triggered, on the differnt combo's i tested, why its not kicking in is anyones guess, maybe cas the Incredible navigator.apk is strictly configured for that device, guess the Incredibles navigators.apk has to be recompiled with new settings !!
I will try it with the cardock.apk tomorrow ripped from the nexus we might have more luck with that me thinks !!! fingers crossed !!!
Keep up the good work! I FINALLY get my Desire delivered tomorrow (after waiting 4.5weeks for stock!!!), so I can have a look at this too... let us know how you get on.
I'm interested in a homedock/multimediadock trigger as well as the car dock trigger. It should be included in the Desire as well as the cardock.
Here's an emulator that could be helpful in the process of developing a dockapp or finding out what's really happening..
http://www.androlib.com/android.application.net-geekherd-dockenabler-pBmD.aspx
I'll try to find the homedockingtrigger if there is any to use in my homemade dockstation
Hi
Wonder if there has been any progress on this? I'm keen to hack my Brodit active cradle to be a fake real dock!

Same here! Any progress?!
after upgrade to froyo, i pluged my car charger in my desire and the car mode icon showed up, even when the other end of the charger is NOT pluged in the lighter. I use a charger for my old HTC Diamond and added a little thing that convert a mini USB port (wich is on diamond) to a micro USB. And the cable on my charger is too short for me so it has been moded (extended) by my self, there is only two wire in the cable for power, so there must be something in the plug itself that triggers the car mode. if only plug the converter into Desire, nothing happened
It's the ID pin that needs to be connected to ground, as indicated in this thread: http://forum.xda-developers.com/showthread.php?t=744636
Finally find out how the car mode is triggerd
short circuit the ID Pin of the micro usb conector to any other pin will make my phone into Car mode and the car panel will popup if installed.
The ID-Pin is the 4th pin of the conector wich is the 2nd from left when desire facing up. Since the pc end of a data cable doesn't have the ID-pin, it won't work like this thread said

can someone confirm that
Can you confirm with pictures or diagrams?
So this means that an amended cable would do it every time?
yes, just like my car charger did, even when the charger is not pluged in the car lighter.
Can you please post pin-out schematics?
Thx.
i think the menu is hidden by htc as the desire does not have the copper pins at the bottom like the nexus 1. hence the nexus 1 car dock wont work on the desire. the nexus one can be charged with the pins and does not need the micro usb for car dock chargings / docking. i guess the car dock software options shown on the desire by accessing the settings widgets are a hangover from the similar software on the nexus 1 hence hidden on the desire by htc.
i have the car dock app installed (dont remember from where though) and it works fine instead with navigation / voice search icons etc.

HTC is coming out with their own car dock. That is why their 2.2 ROM has the necessary support for it.

something like that has been on th expansys and other websites since april / may onwards! so i wouldnt take that too seriously till it actually arrives and car dock works when docking.
at present i use the car dock app which has to be triggered manually but works fine. i use it with the car mode app.
Yesterday i was driving with the car charger inserted in the Desire, when i was moving the cable sometimes the Desire gave a little car icon and my NavApp was activated. Sow i think i has something to do with the 4th pin, and you don't need a certan resistor attatch to it to get it in a certain mode.

That is probably because it needs 2.2 to to work properly. That's why the timing just happens to be after the release of said ROM.
Seems very overpriced if all it does is hold and charge the phone + short some pins together to enable car mode. Seems like anyone could make something to do that.
I some how triggered car mode on my desire yesterday. It must have been as I inserted the charger as I pulled away so may have shorted a pin. but went to car doc mode and had car symbol on status bar and I had to push to exit even after unplugging charger. I have not been able to replicate this since.
I bought 3 mini usb to micro usb adapters from eBay to allow me to use my existing car chargers and all three of them put my Desire (2.2) into car mode but don't appear to work as data adapters in my quick test.
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=310237922332
I see the car symbol and the notification tells me that I am in car mode but what does it do for me?
Thanks,
Since Froyo update I keep getting the car icon in the task bar when I plug the charger in...
Following the instructions I've made a "car dock cable". I intend to use it with a usb car charger when that arrives. I just soldered pin 4 and 5 together, which now gives me the icon and navigator pop up.
I used one of these cables : http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=260636551302 as they have an easily removable micro usb end, plastic cover.
Can you give more details - 4 and 5 on the non Desire end?
Yes, more details please. Would be interesting if I can modify a Brodit active charger..

I also bought an active Brodit charger and it doesn't seem to trigger the car mode, so I am curious if it would be possible to modify to charger in order to achieve this.
Edit: I just sent an email to Brodit and asked them if its possible. Let's see what their answer will be. I post it asap.
I bought 2 different Mini usb to micro usb converters from Brando.hk.
Carmode triggered on both types when i use it with my old Athena charger.
think i paid around 6$ for a converter.
This might be easiest way without cutting cables and soldering.
theese are the converters.

Some chargers just wont charge my phone, for example: iPhone's original charger or a powerbanks portable battery...
My guess is that the voltage is little bit different than the original wall charger and the phone wont charge from it, is there any soft\hard mod to overpass this issue?

What? Iphone's original charger? I don't think it won't ever can be used by our phone. Because it is for iphone. If it is a blackberry charger it can work but not all of it.
For powerbank maybe there is something wrong with the usb cable because mine can work well on every powerbank. Except the last one i used it didn't work but after i change the usb cable it works flawlessly.

wierd
By "Iphone's original charger" I mean the wall plug that you can pull the USB cable out:
[see attached image]
I've tried with three different cables.
BTW, I tried Powerbanks super magic stick, nothing happens when I plug it in...

Why don't use the original charger from the phone? It is definitely compatible though. But for the powerbank i don't seem to know. Sorry for my limitness

I've opened this thread especially because of the Powerbanks issue...
iphone's cherger is only an issue that I've mentioned because it may help to understand the problem.
why?
May I know why you keep calling your charger as iphone's charger? You realise that you're using an Android based phone right?
Is your original Android's charger broken? Why not just buy a new one? Or maybe asks for replacement if it's broken from the beginning.

Oh okay. Is your powerbank working on other devices except your wonder?
Pressing "Thanks" button will be much appreciated if user's posts useful for you
found a way to make it work
I solved my own problem..
It seems that if the connected device is not sending data (like PC or car host) to the phone the device wont charge.
Also I found out that the charger short circuit data+ and data- pinouts so the phone knows its the charger.
All I had to is cut a usb cable in half and connect green and white wires together (on the phone's side)
Not the chargers side! (to prevent potential damage)
