USB SYNC and DATA cable does not work

[dhruvkataria]

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 .

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.

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...

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.

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.

Hi Dhruv,
Go to Gaffar Market or Palika Bazar...and ask for it...u may get it for Rs 400!!!!!!!.

[dhruvkataria]

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 ....
