Hey
Does anyone know if its possible to have some kind of splitter so you can use your foldable keyboard AND have it synced to PC?
I do a lot of testing on the device, and keybaord input is very useful, but don't like having to unplug from keyboard and recradle everytime I need to transfer over a new build of the program.
I'm thinking of opening up my keyboard now... only just got it... but it would be so much better if I could still be cradled.
Anyhow, if anyone knows if its technically possible, ie, does the keyboard use serial and the pc sync USB only, is there any real possibility or am I dreaming.
No, you're not dreaming: a USB connection to the PC and a serial connection to the keyboard can co-exist. I would buy and modify a serial cradle if I were you, since the USB wiring is in there: only the small USB connector inside is missing. You could also just make a Y cable that hooks to the unit on one side, and to the USB port and the keyboard on the other: not as nice, but much cheaper solution.
OK, I just received some nice plugs for the device, anyone know where I can buy sockets? So I can make a part that goes between the keyboard and the device, without ripping open the keyboard and desoldering stuff.
Is the connection socket a standard part?

I'm not very up on how USB works. Is it completely standard?
I was just wondering if there is a mini-usb full-sized keyboard or any other accessories that might work with the universal?
Do PDA's just need drivers and an interface and they can run anything like a PC? With the mini USB port on the Universal is it likely that any mini-usb accessory could work? I saw somewhere that it works with an IBM external HDD, would this also apply to the ZIP disks and stuff?
This is interesting BTW: http://en.wikipedia.org/wiki/Universal_Serial_Bus
you can get cables which have mini usb in one end and any type of usb connector in the other
yes pda's require drivers just like pc's
but that may not be enough
if the pda dont support host mode it would be like trying to connect your
external harddisk with your usb mouse

Oh well.
I'm quite happy if someone wants to delete this thread by the way.
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

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

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.....

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?
with all the coverage the motorola laptop has been getting these days (google: motorola lapdock rikomagic or motorla lapdock raspberry pi )
I got one to toy around with it my self. I'd really like it to work with MHL devices. Thats the moment I found out that MHL's micro usb in is to charge the device and get the HDMI out to work, but doesn't pass though and more usb data though. I imagine the bandwidth is too great.
So as a consolation I thought it would be cool if the lapdock's mouse and keyboard were bluetooth, then i could connect to its display with hdmi, and control the phone with the bluetooth input.
Does anyone know if there is a generic usb device that allows you to connect a USB keyboard and mouse and then transmits though bluetooth? alternatively does any one know of any relevant mods that might help me hack this together?
The problem with MHL is that it uses the electrical path from the USB connection.
The problem is not bandwidth, it's wires.
All of the funny things that plug into a micro USB connector just use the same 5 pins that are already there and repurpose them.
This includes "Carkit", which is the analog headset/ handsfree connection or MHL.
usb flash is also possible to connect and then not get what you
If you wanted to be really hard-core you could add another micro USB connector to your phone.
You'd have to pick off the USB signals as they come out of the PHY interface and before the main connector multiplexer.
Or you could get the guts out of a trashed BT keyboard and wire it to your Lapdock keyboard.
You wouldn't have to get the layout correct, you could just fix /system/usr/keylayout.

I looked and haven't found one. However, during the search I found the KBtalKing Pro mechanical keyboard that solved my problem (well, when it is officially released next month)--it will allow me to use it as my main desktop keyboard (which should be great to type on due to the use of mechanical keys), and also pairs up to 10 devices via Bluetooth as well as one main USB device (probably the main computer). Looks like I'd be able to type on my Android, iPhone 4, PC or Mac simply by pressing a couple of buttons on the keyboard to switch over.
Probably not the economical USB to BT conversion you were looking for, but it's a solution and then some.
You can check out handheldsci com/kb it looks like what you want.
Hi,
Did someone try up this handheldsci adapter ?? It looks indeed as the solution to use any input device/combo without using the usb connection (very useful for smartphones).
Hey guys, I had an i dea on a case, first off im unsure if itll work, but want some feedback of what you think. First, i wanna basically make if a mini laptop type of thing..but still maintain the tablet as it is. The case will charge, have a keyboard, usb ports, and internal storage. I am going to attempt to make the usb box with the storage removable, on the bottom of the case. It would be nice if the keyboard were removable too but thats un important at the moment. For charging im going to utilize the qi(?) wireless charging, build this into the case. In order to power this i will remove the port off of the system and place a deans connector at the base of the case(all connections will use deans connectors cause they are easy and modular) the location will depend on the case, but they will either be at the back along the very bottom edge or on the bottom. The otg adapter will be built into the case so when you slide the nexus in to the case it connects to it. This will also run down to 2 deans connectors. These are how the usb hub will become removable. The usb module will house the port for the power adapter, an un-powered usb hub, an internal memory of some sort, and if the charger is plugged in there will be a switch to change the un-powered usb hub unto a powered one. (will not be using stock qi power adapter, will use something slightly more powerful in order to split the power between the qi and the usb hub. I will be building a circuit for that) All the connections will connect to a corresponding deans plug. Thus making it easily removable and turning it back into a regular case again. Add the wireless keyboard that fits the case, and a wireless mouse and possibly the tablet running full ubuntu(have a few ideas to fix some issues with it for instance the kubuntu desktop over the normal ubuntu desktop to assist in some lag). All of it will be encased in black leather( hopefully i can find the same texture as the manufactures case, if not i may completely strip the case and use only the hard parts(for instance the frame holding the nexus) and create my own case( may actually be my best route).
Also streaming out to tv will be covered via miracast.
So what do you think? Possible? Will it work? Worth while?
What case and keyboard would you suggest? Preferably something cheaper..

Does no one think this is a good idea?

Sounds like a good idea in theory, but if you want a laptop why dont you just buy a netbook
As the person above me said, it's a good idea in theory, but what is the impetus for designing or using this? Not being snarky, just curious what purposes you have in mind for this product or for what situations it could be beneficial. What would be a marketing strategy or hook to interest people that separates it from a laptop or netbook?
