Hi,
I have a USB GPS receiver that is powered via the USB cable wired into my car which I occasionally use with my laptop.
I would like to connect this to my universal, but am worried about it draining the battery.
I have a small Belkin USB hub that has external power (which I can provide from a transformer in the Cig lighter socket) that has one mini USB socket which is usually used to connect to the PC and then 4 standard USB ports.
If I connect the GPS to one of the USB ports and then Universal to another they should both be powered, but will the Universal be able to 'see' the GPS?
I know I could go and just try it, however it would be useful to know before hand incase it doesn't work when it is supposed to due to some driver issues or something similar.
Any thoughts appreciated.
To My understanding this is not possible, the mini usb port on the uni is not capable....there is a word to describe it but cant remember at the moment. The port can onl charge and sync.
it won't work
Sadly this won't work as the uni does not support usb host - it can charge and sync but thats all as far as i'm aware.
that was it "usb host" :lol:
THanks. That's a shame, I'll have to get a BT one now.
Or look for a cradle that will act as the host for both devices. Sadly when I searched on google, most of the returned results are blocked by my work firewall, so I can't see for sure that one exists for recievers with usb plugs.
edit* Although thinking about it, the price of a cradle could well equal a new bluetooth receiver, and bluetooth would be vastly more practical use of your cash.
Thanks, already trying to track down a BT receiver.
Why not?
What makes me wonder is that when my MDA Pro is connected via activesync with my PC, I can browse with my MDA over my PC-Internet connection into the Internet. Why should it not be possible to use the usb connection of the MDA with other hardware? :roll: Isn't it just a driver problem?
Any ideas???
hm
My thought on that would be that your MDA is acting as the slave device when attatched to your PC, not the host.
Hey, here's a market opportunity for you USB GPS manufacturers - add USB Host capability and TCP/IP protocol to your USB GPS device... What? Can't hear you. Ah, Too expensive?. Ah, ok :-(
Anyone got a wm5/ce5 usb host driver for htc universal (pxa270 intel arm processor)? I'm trying to write one, but if someone could save me the effort, please do? I know it will work, as it does under linux.
USB Host on a universal will be great. Didn't know it works under Linux.
driver for view a universal as a sd writer and reader or a driver for the universal for attach a pendrive to a universal?
drivers for attaching a pendrive.
A USB host driver enables you to hook up USB devices like memory key, keyboard/mouse etc. to the universal. This feature is only available on a few pda models made by toshiba, fujitsu, asus, acer etc.

Correct me if I'm wrong but wouldn't it have to be supported by the hardware? As far as I know the Universal does not have USB host so getting a driver wouldn't be much help...
apparently it works under linux so the hardware must support it
Good question. I need the host driver and then a driver for mass storage (e.g. pen drive, hard driver, etc), HID (for keyboard mouse), etc. The htc universal has a usb host controller built into the arm processor (pxa270). The problem is that it also has a usb device controller build in which takes precedent for the mini usb out, so you can use activesyn. However, with the right bit of code you can reconfigure port 2 to act as a usb host. The other problem is that port 2 doesn't have any power (but that is easy to fix with an external power source from a usb hub or battery [I use a single AA battery, (giving 5 volts at 0.5-1 amp), that lasts for 2 hours]).
hi any success yet with the usb host function? is it possible or just a hoax?
nothing personal it just seems that some ppl like to make fun about this topic and spread hoax!
u have any evidences that it works under linux?
maybe this link is helping you in creating a driver!

Suspect that you will also need the proper USB host cable that is used on the Sharp Zaurus under LINUX to let the Universal know that you want the USB port to work in host mode, they are about £10 & available from here http://www.figlabs.com/catalog/product_info.php/products_id/33
I have the Zaurus & Universal so I know the cable fits but I don't have a driver to test.

The USB host is used by Linux on HTC phones, but not for the external USB connector

I have one for wm2003, I not if it worked in wm05.
Yuo can try it?
any success yet??
Dont think I would want to try a WM2003 driver on a WM5 device.

You can do one backup before installing it.
I have installed it in my Universal and I have not had problems with wm5, but it has not worked with my standar cable
I've had no success with it either.. I have a cable that has the correct connectors.. originally used for connecting a usb pen drive to my lcd picture frame.. but like I said no luck with this RATOC driver.

i think that this cable is not enough, what about a 5v power source for the usb pen drive you'd connect?
your universal couldn't supply that, then you need a usb cable that can connect to a power source aswell.
You need to use a powered USB hub if the slave device requires power, there are one or two hubs that run on batteries so you can still be mobile.
You will need a hub if you plan to use more than 1 USB device at the same time.

I didn't know we had it in Linux yet??
In any case, while many devices do use a USB Host or USB Slave chip from a higher level, I believe the Universal talks to its USB as a raw stream device, and therefore can (and does, on occasion) act as a pure Serial communication channel (no discernable protocol beyond 8,n,1) or, therefore, any other type of serial-based channel. Yes, what I am saying is that you could, in fact, hook up a Serial ATA hard disk to an RS232 or USB port directly, so long as the device with the port has low enough level access to the port to absolutely control the data I/O.
The problem you face, however, is that to use the USB port as if the device were the host, you would first need to remove or disable whatever makes it work as the slave. In Windows Mobile that's really not an easy job given the number of different devices and different drivers, some with USB chips, some without... On many devices I can imagine that doing that alone would really bugger up general operation. What happens, for example, to ActiveSync when you suddenly get rid of the port it usually talks to for sync?

Some USB devices have batteries, or have their own power supply You can also get USB cables with an extra (mains or battery) feed wired to the USB's power lines in parallel.
whatever happened to this thread?
allmycrud have you seen the thread from Zeno with USB host drivers?
there is at least one report of it working on a Universal, but I can't get it working on wm6.1... still have hopes though, as all reports suggest that USB host is possible on a uni... can never get verification from anyone though...
Ok,
If I were to make up an appropriate USB cable.....
1) Could I get my P3600 to talk to a USB control box that controls a light display which is normally driven by a Windows PC?
2) Is there any API facility in the Windows Mobile OS that allows a programmer to send and receive USB data packets or would I have to hit the PocketPC device hardware and bypass the OS?
3) Is any of the above possible?
Thank you very much
using usb it would not be posible
usb comes in 2 types masters and slaves
htc pda's are slaves they cant init comm with usb devices
much like that you cant connect an usb harddisk with an usb webcam
trinity have usb host...
you can see in samsung -
http://www.samsung.com/global/syste...roduct/2007/7/7/324600sc32442x__schamatic.pdf
in page 6 you have usb connection,
in trinity we have usb device, if you want to have usb host you will have to change the wiring inside the trinity.
for this change you will need to replace R75 from 470K to 15K, disconnect R83 and make a short from R76 to gnd with 15K(ohm), disconnect R82 and connect Vbus to 5V
(all the numbers of the resistors are for the Evaluation Board, in the trinity it will be diffrent numbers/connections)!!!!!
this will NOT work with your pc!!!! (need more modifications but can be done)
only host option!!!
you wont able to charge your trinity!!! (need more modifications but can be done)
but you can make switch like in the PDF
and then you will have usb host.
i have done some work on the sc32442 chip and it worked with usb host
(not the trinity).
no because the cpu have something dont mean that it's map'd out in the pcb of the manufacturers
and doing a hardware mod can kill the device and will 100% surely void the warrenty
and when all the hardware changes are then don then he needs to write a usb driver for wm to support the
hardware he want to talk to if non already exist
htc seem to use an external chip to do the usb stuff which is basic
only Athena and flame support it

uhm ... very nice impact!
are you know the jtag pins? must be the same like your embedded board.
This is not good...
What is the first HTC device to support USB Host?
Is it that big fat thing with a detachable keyboard (can't remember the name )?
Thanks for the replies.
PS One last question....
Does anyone make an SD or miniSD port based USB controller card?
Thanks again
Is it that big fat thing with a detachable keyboard (can't remember the name )? == Athena
and yes
I'm new in this forum and my english is no the best.
I'm searching for a system to enable usb host on dual. Something have an idea?
not 100% sure about nike but the only htc phone i know off which have usb host is Athena
htc dont connect the usb host connectors of the cpu's (those cpu's which support it that is)
no cure to fix it
Rudegar beat me to it..
no usb host mean that a device is able to connect and use other usb devices such a webcams, external harddisks, mice, keyboards and the likes
yes i now what is usb host, but if is only a problem of connection to cpu we can't study how to make it?I work frequently with electronic and if somebody help me we can try to connet it. The bus of usb are only 2 wire connect it to cpu is very simple if cpu is ready to make it! Somebody have a image of this athena chip and pinout?
wondering if there is an adapter somewhere to allow me to plug in my Evo4g(or any mini USB phone) to an RJ45 connector...for example a console port on a switch/router and use a terminal app to configure it.
is this even possible?
thanks for any info
Wow...
Wow lol, while that's a pretty cool idea I doubt it could work... I use a USB to Serial adapter on my laptop to connect to switch gear with a Cisco cable, this one specifically,
http://www.amazon.com/Keyspan-USA-1...1?s=electronics&ie=UTF8&qid=1318030317&sr=1-1
but the phone itself would have to have a driver for it, or you'd have to custom code one yourself... Either way I'm not sure a phone would even support serial emulation over its USB connection. Cool thought though!
