I used to have a XDA2i and was always aware how flimsy the dock connection was. What type of connection does use USB or some other type.
Thanks

Artemis uses Mini-USB which is becoming the standard choice these days, its quite robust, small and saves you lugging around dozens of different chargers and cables when on the road. If you are looking for a device that uses standard USB, then I am not aware of one, way too big - Mike
Mini usb was what i was on about.
Thanks for the info

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.

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.
Hi,
I am looking for cable that I could use to connect my JasJar PDA (USB mini port) with GPS (USB mini port) and car lighter. This cable should transmit data between PDA and GPS. Also it should power PDA and GPS from car lighter socket. Look at attached picture for better explanation.
Do you know where I could buy it?
Best regards
Marek S
Cześć!
Myśle, że nawet jeśli masz taki kabel, to będziesz mieć problem. And there my Polish runs out!
(trans: Even if you had such a cable, you'd still have a problem).
Or at least I would assume so... Even if you made a mini usb to mini usb cable with power spliced in from a car adapter (easy enough to do after all) then you would still have the problem of persuading your pda to use the usb connection for rx/tx gps data, which I would have thought was a drivers problem...
Anyone?
Hi,
As I read on some forum this device can work as USB host and WM 5.0 has many drivers also for GPS devices. Is that true? If it is, problem how JasJar will communicate with GPS is not a problem. The problem for me is that I cannot make that cable myself and I need sombody help.
Best regards
Marek S
Sadly, this device cannot act as a USB host... I am frankly disappointed that they decided not to implement it, but I guess there always has to be a reason to upgrade to the next model!
I'm afraid I don't know about WM05's support for GPS devices connected via USB, although I think I have read in other threads that people have tried without success to connect GPS receivers to their Universals.
I bought a BT gps receiver to use with mine, and am hoping to cover the cost of that when I sell my IIs, wired gps receiver, cradle etc. One thing that attracted me to the Holux that I bought is that it can apparently be used as a gps mouse if you buy the optional cable - a usb to usb mini that has a curious small plastic junction box halfway along it's length. I assume that there is some form of jiggery pokery going on in there (like swapping the 2 data lines or grounding something ) because I certainly can't connect my receiver to a laptop with a normal usb to usb mini cable.
Sorry I can't help more, but I think you may be stuck unless you can find someone locally who'll chop up some cheap cables for you to experiment with... :?
I am wondering whether if you got a Minu USB to USB B, plugged it into a cheap powered/unpowered hub, the to the GPS would it work?
If it is a cheap hub, when powered, it may have the 5V rails joined, in which case the power might run back to the universal.
However, before testing this, it would be wise to test that the USB can work with teh GPS on its own. If you do not have a mini USB A to mini USB A already and tested (I couldn't see such cables) then www.maplin.co.uk could supply you with the following, which would/should provide you with a connection if it is at all possible:
mini USB A to USB A (Standard with universal surely?)
Female USB A to USB B
Female USB B Female USB A
USB A to mini USB A (Standard with universal)
That is a lot of cables
This cable should transmit data between PDA and GPS.
WHy on earth would you want that?

Once you can prove that the PDA can connect to the GPS that way (one of the posters was not particularly positive on that) then the addition of the HUB would allow you to put the power onto the cable.

Hi Marek,
This is not going to work for DATA but this kind of cable may work to charge both JasJar and BT gps. Log in to www.allegro.pl , find covox in "szukaj użytkownika" go and buy the BT gps with the mini usb port (like G-Space GS-R238) and solder in second usb mini cable into the included car charger .
thats all...
This should charge both....ordered one and am waiting for it, doubt it'll sync though.....

Hi,
I'm looking for regular USB synchronization cable for Artemis. My Artemis was defective and HTC have replaced it, but now I have problems with connection Artemic <-> PC. It looks like cable disconnects from time to time (sometimes when I touch it).
Do you know where to buy more reliable cable? I think my original, shipped with device is connected to loose. Maybe plugs in cables made by other brands are made more solid.
Thanks in advance.
Any usb to mini-usb cable will do, just choose a more reliable looking one at your local pc store
I'm not sure if any mini-USB cable will charge and synchronize data. I saw cables only charging some PDAs (without data transfer), but charging and synchronizing other PDAs in some Internet shop.
Thanks anyway.
My standard USB to miniUSB cable does a perfectly good job of charging and syncing my Orbit.
Thanks,
I bought mini-USB too and it works without any problems (better then cable shipped with Artemis).
Quite a lot PDAs supporting USB-host, but for only a few an adapters or appropriate cables from the manufactures are available.
As these devices support USB-Slave as well I would like to know if there's a way to convert the USB male connector (used as slave e.g. for sync with the PC) to a USB-host female in order to connect accessories (keyboard, mass-storage devices...).
According to wikipedia the configuration of the pins shouldn't differ too much for slave and host mode.
Pls. see attachement, that's what I found regarding this question. It's a picture showing a similar configuration (as new user I'm not allowed to post external links, thanks to ab21cn
from xdaflameusers)
But it's a male-to-male converter and furthermore a converter from "big usb" to micro (mini?) usb. As there're already standard converters for the different sizes of USB I would like to start with the biggest size and to buy the appropriate converter as needed.
Does anyone has a circuit diagram or any other idea for such a generic converter?
Try adapters made for Nokie N800 series
I had a Nokia 770 a couple of years ago. It came as USB device only with mini USB connector, but online I found how to upgrade the software to USB host, and use a cable adapter. The plans I found online involved a 9V battery and 5V voltage regulator inside a metal case (they used a penguin mints case). I built one of those, even using the penguin mints case, and it worked fine.
I have never seen any indication that my HTC phone would work the same, but I am guessing that it might, if the USB host drivers are available.
Google couldn't locate the penguin mints-based converter I originally found, but this seems to be a similar circuit diagram.
Edit: Found it!
thx
thanks for the links. but i'm a little bit afraid of connecting something to my pda which has an own power supply, the risk of a burn-out is given. i've got a nautiz x5 with 4400mA battery which should have enough energy to supply usb-power to connected devices.
I think I'm going to contact the manufacture of my device, maybe this works for me, but a generic adapter would be of use for anyone.
the chips used for usb should be of the shelf as i don't think each manufacture develops an own logic for usb... but this doesn't imply that the cabeling is standard too.
what the heck makes manufactures providing features in their products which the users can't take advantage of?
do you mean using keyboards and so on on ppc?
because it's so simple if ur phone has a mini usb plug (the one u plug the power adapter into). i found a cable that plug into that and plugs a normal usb cable in on the other side and blam been typing on my phone using a desktop keyboard. it depends how much power your device requires however. i wish there was some software to feed a video line out so i could watch videos on pair of vizors that wud be rad. all i can find is a mini-sd card converter now whats the point of that. guess i need an itouch
yes
primary i want to connect usb mass storage devices to my pocket pc. gamecontroller or keyboard would be a good thing too.
my devices doesn't have a standard usb plug, the only thing i got is a adapter from the properitary plug of my device to standard usb male connector, but this is meant for usb-slave use only.
the underlying qeustion is, if there's a way to convert usb-slave to usb-host using the same pins. if it needs an additonaly pin then i don't see a way to convert it as i don't know anything about the pins cableing of my properitary plug.
a week ago i found an adapter which was able to convert the male usb to another male usb... but it didn't work.
the problem is compareable to datatransfer between two pcs via usb - it's possible, but only using properiatry hardware and drivers...
so i think there's no way to solve this problem in a generic way.
out of interest, do you already have windows CE drivers for the device to act as a host and mass storage? I wouldnt mind them if you can point me somewhere..
how to check if my htc (touch2) ca use usb host?
unit arrived on time and packaging was well done and i like the fact that Aukey uses materials that are recyclable which i thought was a great plus. the unit is aluminum and has a great look and feel and nothing flimsy like some other units i have had. unit has 4 usb ports and one blue LED to notify that the hub is connected to the computer, very simple to use and see that your connected. The port that is used to connect to the computer is on the left hand side while the ports at the top are used to connect peripherals. The bottom also has two non-skid rubber feet at the bottom which i really liked and made unit secure on my table and didn't move around when connecting a hard drive or other usb items.the 2ft usb 3.0 cable provided was plenty of cable but not too much so you don't have extra cable laying all over your workstation and unit itself uses its small size very well also. Package contents: Aukey 4-Port Hub, 2FT USB 3.0 Cable, Instruction Manual. Free lifetime technical support and 18 months warranty. the free technical support was a nice added touch you dont get with alot of other retailers and one i liked to see. data transfer rates of up to 5Gbps, you'll be able to sync files and interact with your Mac or PC more efficiently than ever; backwards compatibility with USB 2.0 / 1.1. overall i loved the simple design and great looking unit and highly recommend this product
