I've seen this mentioned in another thread (to connect a CF device to the serial port) - does anyone know where I can buy one? Google/kelkoo/ebay searches aren't showing anything.
You mean something like this?

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.
So I found this Mini USB that plugs into the bottom if my T-Mobile Wing(HTC herald) I'm using the standard WM6 with no mods at this time. I was wondering if anyone here had ever used these for anything. IE can I plug a flash drive or camera into it and possibly with some app utilize my device to so. I searched and didn't find anything similar so i thought you guys might have some interesting ideas. thanks
in general no htc device (besides the 7500 and 9500) are able to host usb so far, as far as i know. i am not sure whether that is a real hardware restriction or a driver issue. maybe you could post a link where you found that, and what the actual purpose of that thing is and we could have a look into it, i would love for this to work, but i still doubt that
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 the announcement that ICS will support USB Mass Storage, I was wondering if anyone had found a Micro USB card reader similar in size to the USB Jig shown in this thread. I saw one a long time ago that was used to flash phones of a specific make, but I can't remember where I saw it. Can someone help me?
PS, I know this is a question, but I figured it fell under Accessories. Please don't burninate me.
Do you mean something like this one, http://www.amazon.com/elago-Mobile-...FKR8/ref=sr_1_2?ie=UTF8&qid=1322087237&sr=8-2 ?
Sort of, but a micro USB port, not a full size USB. Like the port on the bottom of the phone.
Well i don't think they make things like that for consumers, but from that video hey seems to have just used a regular microUSB cable.
As I said, I saw one out there for a specific phone maker that they use for flashing. I can't imagine that someone in China would not make them for sale. I'll keep digging, I guess. Thanks for the response, though.
wait, http://www.ebay.com/itm/Samsung-Gal...ccessories&hash=item3cbb7b1e8c#ht_2377wt_1163
is that what you're looking for?
No, but that's the size I'm looking for. An MSDHC reader that size with a micro USB plug like that has.
I have that on the way to put in the toolkit, though. A USB jig comes in handy.
I thought that announcement was that ICS, having usb mass storage support would mean that it's like how current android roms are. When you plug into the computer you can put it into usb mode to transfer files. It was previously thought that ICS would not have that and would require transfer thru MTP protocols only. I dont think it means you could just attach storage via micro usb such as external sd/hard drive.
No, they're talking about hooking up external storage. Someone was talking on Reddit about hooking up a dongle and a USB flash drive to their phone and how it worked for extra storage when they were going on a flight.
I believe what you are trying to do requires usb host support but I know what I'm saying is not the answer you are looking for so, I'll leave this be for now. Good luck in your search.
I'm pretty sure sure our phone does have host mode support. So you can get a USB host mode cable on ebay for $2 shipped, and attach a standard USB drive. Not the compact solution you are looking for, but it will work.
You are correct. It's not exactly what I want, but it would work. Thanks.
Did you find such a thing (micro-usb to microSD) ?
I have been searching crazy lately (like you, I can't believe that some manufacturers did not had this good idea ?!), but nothing !!!
And I am about to DIY one, based on the following example (but with micro-usb):
http://forum.xda-developers.com/showthread.php?t=1713914
I think, I am going to start with something like:

The final goal would be to create a micro-usb to microSD adaptator as small as possible ...
Any better idea ?
I know that there are a LOT of topic about USB OTG while charging but I haven't found a good answer to this "problem".
There are people which achieved it using this cable (Please check Y_Cable under attached files) but there are also a lot of people which say that it's not working.
While googling I found this schematic and I can't really figure out why this should not work
I'm under 10 post, please check Y_OTG_Cable under attached files.
I also had an idea about a separate charger for phone and usb device, here's my schematic, I do not know if it this can work but I really cannot see why
Please check OTG_Charger under attached files.
What do you think?
