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

Bummer
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.
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?

am I right to say that all wp7 phones have USB Host support ?
that would be real cool ( think of external key-board over usb)

This is more like a sampling of the goodness to come from the current crop of humble WP7 phones. The HD2 never had this A/V out ability. The HD7 clearly does have it...as well as all WP7 phones.

Snapdragon does support it-- the Toshiba TG01 had it, and the HD2 had a (buggy) implementation hacked in. Issue is that any client devices will need their own external power source, because these phones aren't giving out any juice on their USB ports. So even if software support is added, if you have to attach a Y-cable and an AC adapter to plug in a keyboard (or lug around an extra set of batteries), then what's the point?
Also, most of the point of USB Host support is to be able to interface with external file storage, which is useless with WP7, or external devices-- also useless, as WP7 has no APIs to allow for apps to interface with such hardware.
or make a real cool OBD2/CAN logger/writer (auto motive )

Not sure why this is just getting reposted around the web without question. A/V out over USB? Out to what? Nothing takes an audio/video input signal over USB-- it's not a video cable.
You can use the bus to transfer files or other data using your own protocols over USB, but USB 2.0 does not have enough bandwidth for (uncompressed) HD video output. If you send it compressed (presumably just in the original video format, as these phones are not powerful enough to transcode on the fly), then you're essentially just using the phone as a USB flash drive and thus would need a receiver (externally-powered) that can process the file and actually output the video. A simple MicroUSB port is not going to be able to output anything directly.

This could be like in Apple devices where thy can recognize what is connected to port (headphone jack) and switch it to different mode...

Apple devices can recognize that something's connected to the headphone or dock connector, but they don't reassign pinouts on the fly for non-proprietary connections eek. Using a MicroUSB connector to instead carry a video signal would probably require hardware changes (and violating the standard).
HTC's solution was to build ExtUSB, which fit MiniUSB ports but also added some extra pins for audio and video, and Apple of course has its dock connector, which has more than enough pins to reserve a few for video.
I am definitely pleased to hear about this. I am trying to get my wife sold on Android, but she wants an iphone just because it can dock with our sound system. *cringe*

All we need for that is serial bluetooth support.

well if you read reports, they are already using this at redmond for presentations so it must work somehow.

It does. The Droid Incredible has been using it since it was released.

Galaxy S supports micro-USB to HDMI interface.
EDIT: I guess you can scratch that, just checked with Samsung the earlier announced micro-USB to HDMI cable is no longer available, and the TV-Out currently supported is via headphone jack to RCA input on your TV, bummer...

That's a specific hardware feature of the Droid Incredible (the cable does nothing when plugged into any other HTC device), and it outputs through composite (NTSC- roughly VGA), not an HD signal.
I was thinking about this and I'm actually pretty excited about it. Sitting in the car waiting for the kids after school I could watch netflix on my stereo's 7inch screen, or at work, I could plug it into the breakroom tv to watch movies, etc.
I hope this gets added.

The point being made is that WP7 devices can output an A/V signal from the microUSB port. That's all that is being said. Someone said the USB port could not output an A/V signal. The Droid Incredible was mentioned because it does output an A/V signal through its USB port.

A model-specific proprietary use of USB pins for a composite video signal through a custom cable/port design is very different from Microsoft suddenly being able to enable A/V out on standard MicroUSB ports in WP7 phones on an OS level.

Did you ever consider the port might not be standard? I think MS can do pretty much what they want. They are the masters of this stuff.
Thats pretty nifty there buddy =]
Hello,
At work my monitor has a port for VGA and HDMI. I would like to hook up my handroid to the VGA Port to mess with my girlfriend via remote desktop. Due to the fact that this isn't very serious, I want to avoid purchasing a bluetooth keyboard/Mouse, and utlize the ones on my desktop.
That means I'll be running an OTG cable, to a splitter, splitting to a USB Keyboard/mouse.
Those bits work no problem. My question is if anyone knows if this video cable will work:
http://www.amazon.com/TRENDnet-Cabl...BSL4/ref=sr_1_4?ie=UTF8&qid=1337117122&sr=8-4
It's the cheapest one I could find.
Any help would be greatly appreciated.
Thanks,
Mike
