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.

It's great that there's USB-Host drivers available for the PocketPC, but I can't seem to find the USB Host cable I need to connect USB devices.
Does anyone know where I can buy a Mini-USB to Female-USB cable so I can connect a USB mouse, USB digital camera (as drive), etc?
The USB Host driver for the PocketPC is here, although I'm yet to find out if they are WM5 compatible.
You could try Maplin for cables ( www.maplin.co.uk ).
I hate to imagine the effect that USB host activities will have on the Exec's battery life... :shock:
I would be very interested to find out if they are WM5 compatible !
Nothing about it on this site....

I hope you prove me wrong, but In heard that the CPU in the JJ supports USB host but the rest of the additional hardware to suppoort it was not included. basically the JJ will never support host activities.
Does anybody know whether it is possible to connect a USB GPS mouse via USB cable to the Universal? Universal should be able to act as a USB host, so it might be possible. If yes, any ideas on external power supply? Maybe via USB cable splitter?
Thanks, the Modifier
No-one's yet posted to point out that the Universal cannot act as a USB host, not sure if you've been PM'd yet - I thought I ought to point this out just in case someone saw this thread and thought it confirmed that the device did.
IIRC from reading other posts, it is not possible to connect a GPS mouse via cable to the Universal. I would imagine that this is a drivers issue though (?) as the 4 pins on a usb connector should be able to deal with v+/-, rx and tx...
Anyone care to comment on the feasibility, I would prefer to be able to use my serial GPS unit than buy a new one (well, ok, no I wouldn't, I want a battery powered SirfIII BT device I can use on my mountain bike and this is a great excuse, but I *ought* to use my existing gps box! :lol: )
It's not a driver issue, it's a hardware issue. Physical bits for a host are different than for a client USB device. The Jasjar (Exec) is a client device and you aren't going to be hooking another client to it.
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?
Hi,
I've been wanting to hook up my desire hd to usb hosting and have not been able to find a cable for it.
I was wondering would it be ok if i connected a micro usb (male) to usb b (printer version) (female) adapter
to a,
standard printer cable with usb female at the end?
This would result in one end being a micro usb male and the other end a female usb
I look forward to your answers
Thanks alot for reading
That probably wont work.
I in fact saw an article yesterday, but can't recall the link. (Will look now).
IIRC, you need to modify the USB cable somewhat to get the DHD's USB port to detect an OTG connection.
Edit:
Here we go: http://gigaom.com/mobile/how-to-add-a-usb-keyboard-to-an-android-phone/
I think if the software supports usb host mode, with a 'micro usb type a' to 'usb type b' cable you can connect to a usb device. That is if the DHD is equiped with 'micro usb type ab' receptacle.
oh wow, ok thanks ever so much!!,
however, i just need to confirm what three cables you need so i can go out and buy them, i need:
Car charging cable (which one is this?)
Micro-usb cable (is this with the microusb male on one end and a standard usb male on the other end?)
USB extender cable (is this with one usb male and usb female on the other end?)
thanks

I have no idea really, but if you are successful, let us know
I'm just having trouble understanding what cables are needed.
On the website you gave me, it says i need:
a car charging cable, a micro USB cable and a USB extender cable.
Is this effectively two micro usb cables and a USB extender cable?
or does one HAVE to come from a car charging kit?
please help!!
thanks

Nice find! I did see the mini one only
Gonna order and try it out. No great financial loss if it does not work.
Obviously we will need a USB Host module for the kernel if not already present. Will check tonite.
i've finally made my host cable!!!
i now need micro-usb dongle host module. Is this where you have to get hold of a car charger and get the end of it and unsolder bits?
The USB Host module is software. It is loaded by the Linux kernel.
ok well i need to get that too.
Also, whats the bit with the car charging cable? what that for?
I'd be really interested in this as well. Would be awesome if i could just connect a usb drive or my camera to my phone to copy data.
So does anyone know if a host driver is available for the desire hd.
I really have no idea how it would work, but it should, as loads of tablets are able to use 3G-Sticks to connect.
Today I recieve my USB Host adapter cable for the DHD.
When I plug it into the DHD and connect a USB Hub the car panle ("Auto Bedienfeld") starts.
Connecting a USB Keyboard to the USB Hub doesn't show any impact. But this is what I have expected. Next I try to integrate the patch from sonic74 to a kernel for the DHD.
http://sven.killig.de/android/N1/2.2/usb_host/
At the moment I use Android Revolution HD 2.0.9
Any progress?
I really like the USB host future on my Desire HD,
I want to connect my USB Drive to my DHD if this is possible? So i have 16GB More storage if needed ;D
I've ordered the converter thing from dealextreme, someone that could make a flashable zip to enable usb host functions?
Was also quite interested on this.
My wish is to connect my dSLR to the phone, and move all jpgs/nefs from there to a internal card. Or copy, and use the device for better visualisation.
As the camera has its internal battery, power shouldn't be a issue. It would be awesome
I am still working on this.
At the moment it is working for a short time, but then there a same errores.
This meens it should be possible, but same more research must be done.
My Kernel is based on the BUZZ 1.3.7 Kernel, and following patches:

Quick Q: What did you connect? Or you didn't connect anything ?
Hello -
I have been looking all over for a cable that will work for what I am trying to do but I just can't find exactly what I need. Maybe I am looking for the wrong cable type?
I am trying to plug my Seagate Portable 4TB SS HDD. into my Rooted Galaxy Tab S3 SM-T820. I dont really understand what cable type
I need when I look at my Tab. I guess it is a Mini USB Type 3.0 - C ?? The only cable that I have that fits it is the one that came with the tab.
Am I looking for a Mini USB C 3.0 ( adapter to a ) Solid State USB 3.0 ? ? ? - Please look at the picture to see what type of connection my HDD has.
It is 2 connections in 1 . I assume part of the cable is for power and the other side of the cable is the transfer side. ?
So I guess my main question is: What cable do I need ?? ALSO ... If I cant hook up to the Portable SS HDD, then how about just hooking up my Tab to my 3.0 USB slot
on my desktop?
Thank you !!
You have three concerns here.
1. Power.
2. Cable.
3. Compatibility.
*If* the tablet can power the external drive, and the external drive is compatible, a usb c to micro usb 3.0 cable will be all you need.
If the tablet and the drive are compatible and the tablet can't provide enough power to he drive, you will need a powered hub...tablet connects to the hub, the hub connects to power and the external drive.
as far as compatibility, you are *probably* fine, as long as the drive is formatted FAT or FAT32. If it's NTFS or something besides EXT, you are most likely hosed.
Good Luck!
Buy Type C adapters that are designed for Mac books. they work great with Tab S3. Just make sure it is USB 3.0 or above.
