I got a problem with a docking station I bought.
For a while it worked fine, and then when the power cable and usb cable were both connected at the same time and I docked my T-Moblie MDA touch (elf), my computer shuts down.
It's hard to imagine that I have tweaked the device in a way that I caused this problem, but "what the hey" doesn't cost anything to ask.
Any ideas or suggestions?
Thanks
Try using the USB Cable plugged in a HUB with other devices instead of direct to PC.

HI
I bought a USB SYNC AND CHARGE cable from http://www.pdaaddons.com.
The cable is able to sync the PDA but not charge it .
http://www.addonsworld.co.uk/product.php/21603/578/
I am not sure if I have been cheated or is there something wrong in what I am doing .
I had a cable for my IPAQ 6315 and it use to work beautifully .
Can anyone tell me if they have bought cables from PDAADDONs.COM and if they have worked.
Dhruv
hi..
Im not an expert but i think the charging might have something to do with your computer, i dont think all computers are able to sync and charge through the same USB port...
Have you tried any other cables???did they ever work??? as i say im just kinda accurately guessing the prob...

Subject: i've got the solution!!!

Hi everyone, i think i have the solution of XDA II not charging on USB port using XDA sync/charger cable... if u want the XDA II charging from USB, just open up the connector and disconnect the 20,21,22 pins from USB bus power line. After that, u can use XDA sync/charge cable in any USB port and they will sync and charge the XDA II.
How i know this??? 'cos i "reverse-engineered" the connection of the cradle... i was wondered y using the same usb port, the cradle can charge while the sync cable can't... so i test all the connection of the cradle and found that pin 20,21,22 and also pin 2 is disconnect. The pin 20,21,22 only connected to power when u plug in the DC into the cradle. This mean that pin 20,21,22 connected to DC (+) while the pin 2 is connected to DC (-) only when u plug in the external DC supply to the cradle.
I've modified my XDA sync cable and now i can charge my XDA II on any USB port even from my laptop. Hope this helps for those who purchased the XDA sync/charge cable to use with XDA II.
To those who like to go further....
The only problem that i can c now is that if u modified the cable and u use it with a car adaptor, will it charge the XDA II as fast as possible like when u plug in the external DC supply? OR will it only trickle charge the XDA II as using USB port? i really don't know 'cos i don't have a car here with me to try it out... but i think it will only trickle charge the XDA II only...
Therefore, to those who like to get charge faster in the car, u can install a small switch connected between the USB power line and pin 20,21,22. By switching the switch, u can choose between trickle charge and fast charge.
I can somehow understand what you are trying to say .
1. Why are these websites selling cables when they dont charge.
2. Can i do something at home to make it work.
3. How do I know if my cable has the right connections.
4. Can there be something abt usb 1 and usb 2.
Dhruv
USB 1 or 2 is not an issue. I charge and sync with my cable from proporta.com on my Dell laptop which is only USB 1.
Some computers don't kick out enough down the USB to power external devices so I presume charging might be the same. You haven't said if you've tried it on other PCs? If you only have 1 PC, go to a friends and plug it in. It'll ask for drivers but cancel out of it and it should be charging. If it doesn't charge off a full size desktop then its fair to say you've been 'stitched up' or it was never meant to charge. Simple really.
Dhruv and others....
There is a simple kit, now a days which we get in market, which has a USB cable, a car chaqrger and a power plug.The Cable can be used with both Car and Power pluag and for Syncing AND IT BLOODY WELL CHARGES THE XDA TOOO....works with XDA II as well as with Blue Angel.If one uses universal USB 2.0 a Magician can also be then compatible...
Price!!!!!! 12 USD....!!!!!!
Usb Sync
do u have the link

Hi Dhruv,
Go to Gaffar Market or Palika Bazar...and ask for it...u may get it for Rs 400!!!!!!!.
USB SYNC AND DATA CABLE
what is suprising the cables did not work on my notebook or my pc at home but when I used it in office it works just fine.
So there is something to think about :-
is it the usb power managment that creates this issue .
or
windows 2000 patch ....

I have a tomtom bluetooth gps receiver that I used to use with my xda-ii for my satnav solution. I had a car charger that charged the xda and tomtom unit at once. I have now upgraded to the Exec and am hoping to find a similar car charger but couldnt find any on google/ebay - does anybody know of one that exists?
Thanks
Allan
Cannot be of help, but looking for the exact same solution. I had an iMate JAM and a cradle that charged that (mini-USB) and had an output for TomTom Bluetooth. If all else fails I could try taking apart the adapter because it has the correct output, just the Exec won't fit in it!
assuming the TOMTOM gps receiver uses a round 5V center positive connector to charge it ( which it almost certainly would do )
then check out my posts in this thread,
http://forum.xda-developers.com/viewtopic.php?t=29351
the cradle even comes with a wire just for charging BT GPS receivers
Ouch! Thats a little pricey!
I already have a mount that holds the unit, so I am just looking for a calbe charger solution. Anyone have any links?
Thanks
Allan
in that case I have seen a car lighter plug on ebay that has a USB socket in the back, it was on £3~£4 you could then use a regular sync and charge cable to charge it
o2 shops are now stocking the car charging lead... complete with natty o2 shaped blue indicator!
To get round the problem of daisy chaining mounts and receivers, I got a great car charger - dual usb adapter from eBay (I searched for "dual usb car") which gives you 2 usb sockets for about £8 all in. Having bought this though, I'm thinking of installing a spare cigarette lighter socket behind the dash to power it from and cut down on cables in the cabin...
Funnily enough, the many Sync and charge cables for the Sony PSP would be able to simultaneously charge both a Jasjar and a bluetooth GPS unit
here is an example

Universal charger- special
The Universal as well as the Typhoon, Wizard etc. need special wiring for the mini USB. when connecting to the computer the the driver is activating the proper pins in the Mini USB socket and you can see the "charge" light on. However when connecting to a USB Poer Supply, pins need to be manipulated (some to ground or perhaps to Vcc). I'v looked into this issue many times (searching in the Internet) and could not find a proper wiring diagram. although I know for sure that they are exist as there are some Car working chargers offered for Universal / Typhoon.
In any case refering to this thread, a car charger that works for Jam/XDA2Mini most probably will not work for the Jasjar/Universal unless i is apecified as a Universal car charger.
If any of the memebers has come a cross a wiring diagram for Typhoon / Universal charging scheme it is appreciated if you could provide details.. as many of us would like to build their own car charging units.

Dude, what are you talking about !! I use the sync lead from my kodak camera to charge my JJ from my laptop it works fine but is slow (my laptop hasnt got much umph) and the same goes for the PSP power lead I mentioned earlier, I use that in the car with my cradle that happens to have USB sockets in it, (pictured in another thread)
It seems that either your usb lead has the proper connection to fit the requirements of the JJ or I am doing something wrong that I am not aware of.
Here is the test: Just take a Powered USB Hub, connect XDA1, XDA2, XDA Mini, XDA2S (all the models that I could test right now) and It seems that the Powered USB Hub can charge these devices.
Now connect the JJ (I suggest with a traditional USB syc cable that comes with either ..) and NADA I got no indication for charging .. than connect the HUB to the your computer which has the ASYNC installed and you see that immidiatly the JJ is being charged. Both feeding measured at 5.15V.
The Typhoon behaves the same for me as well.
Further more, I have few USB chargers (other than the one equipped with the JJ) which is in fact a PS with a USB port . The result of connecting the PS through the traditional sync cable is "No Charging".
The same applied to many Car USB charger that I'v tried.
Perhaps your Kodak sync cable is special (in fact I am looking for the schematic diagram of a cable like this)?.
I tried (just now again) also with Dopod 828 and it seem the same (no charging unless it is connected to the computer).
Please double check your charger cable and try th sync cable that comes with the JJ.
I dont see why kodak would have used a special sync lead, because on the kodaks it is used for data only (power comes in via a diffrent connector) when I get a chance I will buzz out the cable for you !!!
PS I think you shold plug it in and wait, mine starts charging instantaneously when used with the mains adaptor which has 1 Amp of current available, but takes a min or two to start charging when I am using my laptop/in car charger, both of which only have 500mA available.
Car Charge
From reading other threads, Pin 4 in the Mini USB is shorted to ground and that's probably turn on charging ..
I suggest that you read threads about the power charge / car charge in other forums... here is an example I took and although it talks about the Typhoon it is relevant to JJ as well and it suggest to connect pin 4 and 5 to ground. I can't have a good explanation why your JJ starts to charge after 2 monutes. I suspect that it has nothing to do with the current that can b drawn from the PS.

Here's what I've found on modaco.com forums, posted by richwookie on Oct.4 2004:
QUOTE >>>
...I've hacked open my C500 mains charger (quick, where's the superglue), and sure enough there are only 2 wires leaving the box to the mini USB cable, GND (black wire) and VO (white wire). However, after very careful probing, with a very tiny probe no less, I've established that the GND wire is connected to both pins 4 and 5 of the mini USB connector.
Now usually pin 4 would be not connected to anything as pin 5 is normally GND. So next I probed the C500 data cable to see if pins 4 and five of the mini USB were connected together. They weren't of course.
So what does all this mean?
Well, from what I've discovered I conclude that the C500 will only charge if:
1) There is data on the line (even if it isn't saying anything :wink: )
OR
2) Pin 4 of the mini USB plug is grounded.
So what's the solution to making the generic car chargers work?
Do nothing to the car charger. Mod the data cable so that pin 4 at the 'mini' end is connected to ground.
This IS all speculation and I suspect that it is easier said than done. I haven't yet hacked open my data cable, but I expect there are only four wires in it, and the only way to ground pin 4 (mini end) is to somehow bridge them at the connector. I think that is beyond my soldering skills (have you seen the size of the contacts on the plug?!) but I may give it a go anyway.
Anyone else want to try? Let us know here.

... and the 2 hours later:

Posted from my SmartPhone while it is charging in my car using a 1.49 cigarette lighter USB adaptor and my newly modded C500 data cable!
I'll let you know if it still works as a data cable when I get home. ;-)
....
Modded cable doesn't work for data now.
When I connect it to the PC it just charges. I suspect that when the phone is in 'charge from adaptor mode' it inhibits the data lines.
<<< UNQUOTE
Well, I guess it's simpler to mod a USB cable, than either carry around a charger, or install Activesync everywhere.
With all this chat about modifying pins etc call me naieve but why not just buy a dedicated charger from expansys or an o2 store ? both cost between £10 - £15
:shock:
Just an observation I have made... I have an O2 EXEC, and charge it quite happily (sort of) with the Standard USB Synch cable and a Car Lighter Socket USB thingy.
The only thing is... It will NOT charge if the EXEC is on (screen lit up) when the USB lead is connected or power connected. Switch the device off, connect the lead, and the charging light comes on.
I find the same when I connect it to the computer with the Synch lead too. It won't connect to ActiveSync or Charge if the EXEC is on when connected.
Hope this helps.
It's got USB, although the charging looks a little scary.
Anyone tried this one or tried any of this company's docks? They all seem to be built similarly.

I have it.
After buy: You can't use it with your gel case, or something like that, you have to connect it alone.
It's dificult to connect it right.
It isn't like the one of motorola, this one it's less stable, i think.
BUT:
Its work for what it designed to.
Usb and Power both cables work right.
If you can buy and OTG with mini usb you win
PS Sorry for my english.
PS2. I have it, right now its connected to my computer
I don't like the fact that it looks like you could accidentally inject 12v DC into the USB port by plugging the power into the wrong mini USB socket. If it had a coaxial power plug I'd be all over it, but since I added a usbotg cable to my stock zoom cradle I don't think I'll be getting one.

i dont even know how that would work, it must charge it brutally slow since it's mini usb...
it looks like a 12v plug with a mini usb plug on the end of it.
I've had that dock wishlisted for a while.
@lfiuse
Thanks for the quick review. Are the ports at the back clearly marked for power and USB? Like zn706, I'd hate to plug the power adapter into the usb port...
OTG would be nice...
Hi guys
I bought a charger (Sony/Ericsson) for my car that has given some trouble. For some reason my Galaxy Nexus switches off when I try to charge it using my new car charger. The same happens if I use the same cable from my laptop.
A colleague can use the cable to charge but his phone (Galaxy S II) is no longer recognized by his PC (his own cable works fine). I can charge using his cable without any problems.
Another colleague started talking about different cable versions... but really... it doesn't make sense to me.
I have had the same problem with the original cable that came with the charger and with a new cable I bought as I assumed the original one was broken.
Does anyone here have any specific usb/micro usb knowledge and can tell me if there's anything special I should look for when getting a(nother) new car charger/cable?
Thanks in advance
./kroogar
I know one can short a USB port and cause a computer to reboot on the spot as if it lost power. It's done by inserting like a key so that the key connects the 5v + and ground contacts within a USB port. Maybe that's what's going on here- the way the cable is made, the micro USB part makes contact with all the pins, but also inadvertently connects the two for power?

I tried taking my normal PC cable to the car and it worked like a charm. So I guess I must have gotten hold of two (!) flawed cables... what's the odds?
Thanks
Hello, I'm sort of the opposite of an expert, more like the one that needs an expert. I have been searching endlessly for a hub to connect multiple devices, in my case my A70 and a PC or TV or soundbar while my phone is reading from USB and is also charging its batteries. I ordered hub that promised that anything with this kind of USB C connector would work but of course, it does not work. What if anything works? Alternatively, the same thing applies to the Samsung Tab 10 (2016). The point is that I want to run my music from the music app on the phone (or tablet) while it is reading the music from the USB and plugged into a power socket. (?) Thanks for any help!
