Cannt help but think that I am missing something very simple here.
I have just gone to plug it to the PC and notice that the socket on the bottom of the phone isnt mini USB.
However, the USB lead supplied with it is mini usb. I have tried to force it in, but it wont go
Am confused.
yer putting it in upside down. it's mini usb. trust me
<blush>
thanks
Its a special type of mini-usb called an HTC EXTUSB that allows voice as well as data...
Turn it the other way around. You've got it upside down.

Hi there,
let me first thank you for this great site you put up here!
And here comes my question:
I want to hook up my USB GPS Mouse (made for the notebook -
meaning it get's it's power via USB) up to my XDA.
And now I wonder if I can simply solder the data +/- cables
from the USB Mouse to the USB data +/- pins on the XDA plug
(so I could still use the same cable for ActiveSync on the PC),
or if I have to solder the data +/- cables from the USB mouse
to the serial RX/TX pins as described on the 'The XDA's connectors'
page of this site...
I was planning to hook both the GPS and the XDA up to my car
power adaptor in a kind of a Y constellation:
::::::::::::::::::::::::::::::::__________ Power
:::::::::::::::::::::::::::::::/
::::::::::::::::::::::::::::::/
::::::::::::::XDA ----------
::::::::::::::::::::::::::::::\
:::::::::::::::::::::::::::::::\___________ GPS
and use Power for both.
Maybe someone can tell me about the data hookup.
Thanks, Lars.
I don't have answers but some things you have to consider.
1) The XDA is a slave device. I presume the GPS receiver is one too. I really wonder if they can communicate with eachother
2) Based on how you describe this you want to power the receiver from the the car. I assume you have checked the right voltage requirements for the receiver and that the powersupply can deliver the currents required for both the XDA and the receiver. My personal experience is that the latter shouldn't be too much of a problem, but it can't hurt to check.
3) Combining USB and Serial the way you describe it is not a good idea. (mark the last character '.' as in PERIOD).

Power Supply
Hi Robert,
thanks for your suggestions.
Indeed both (the original ActiveSync cable from the XDA and the
USB GPS) get their power off a USB port on the notebook so
this must be the same voltage requirements.
This ActiveSync cable is a combined car charging cable with an
USB 'A' type connector on the end which you can plug either into
the USB port on the notebook (where it also ActiveSync's) or into
the car's power adapter (where it only charges).
So this both same voltage. And the car power adaptor should
nominally supply enough power for both...
But I don't understand what you said about it not beeing a good
idea to hook up the USB data to the SERIAL data.
When plugged into the notebook in WinXP the USB GPS installs
a 'Prolific USB-to-Serial COM5' to emulate to the programms
working with it a com5 (or com1 or com2 depending on your
hardware settings) communications port. So I guess the data
coming from the USB GPS is just the same as if delivered via
serial cable and all the driver does is faking to be a serial port
to any programm asking for data from com5.
And I think a USB device is 'not really' a passive device as it starts
popping out ASCII data strings as soon as it get's power (no matter
if there is a device to read the data or not).
So I figure when you plug it into the XDA and tell the XDA by means
of USB wakeup (USB_VDD pin 13) that there is an active USB
connection, that it will start trying to figure out what the heck the
connected cable is trying to tell it.
And here is the tricky part where I don't know if the XDA might not
believe it is beeing Sync'ed and therefore starts ActiveSync.
Anyone with any experience or suggestions there...??
(Sorry for the rather lenghty post)
Greetings, Lars.
Lars,
seems like you got the power all figures out
regarding the usb/serial discussion.
If I understand you correctly you can plug the USB connector of the GPS receiver into the USB port of the PC.
'somewhere' in the PC this is modified into a virutal serial port in order to enable serialport aware programs to work with the GPS receiver as well.
This is a good concept but at an electrical level that still means that the GPS receiver is connected in an USB fashion. There is nothing Serial Port about that. In a way you already pointed that out in your messages by using the word 'emulate'.
You can hook it up to the USB part of the XDA but still I doubt about the master/slave discussion of USB.
Regards Robert
No cahnce.
Save yourself time/money.
Forget it.

Guess U R right
Hi Guys thanx for the feedback,
I spent an afternoon researching on this stuff and am very disappointed that I have to admit you are both right.
Now way (other than putting some 'intelligent' converter between the USB GPS and the RX/TX pins of the XDA) to make the USB 'language' sound like 'SERIALean'.
I think there should still be a possibility:
Let everything run via the USB, persuade the XDA it's not ActiveSync talking to it and write a driver that talks to the GPS via the open USB connection and sends the proper commands to recieve the NMEA ASCII.
And then you would still need to tell your route software to take the incoming data from the virtual (or emulated) COM port...
And when I read the above chapter once more :shock: I find this is definitly not a job for me!!
So I will just get a serial GPS an hook it up the nomal way.
Cheers and thanx again, Lars.
Hi,
Just read your post. I am new to pda land. Just bought a xda2
I have a laptop which I use with a gps usb mouse via usb on the laptop. Am I right in thinking that I could have bought a ps2 mouse and used a ps2 changer to usb and it would have worked??
If so can't I buy a usb to ps2 changer in order to plug into a car connection cable which has the ps2 and the xda conection and a ciger lighter plug for power? OR is there a similar cable for a usb connect for gps?
Am I missing something here?
Thanks

Usually when i connect the phone through the mini usb cable to the pc it syncs and everything is fine.I tried to do it today.The specific sound when in plug in the phone is gone.The led indicating that the phone is charging is off.I have a HTC prophet and it works fine with same computer,same cable.I tried hard reseting the phone, it did not help.Ideas?
As expected, it was a problem with my mini usb port.As it is not broken yet i found that inserting the cable and rotating it a little bit (as much as the port itself allows) counterclockwise will reestablish the connection .The only question now is can i manually replace the mini usb port?
There's already a topic on this:
http://forum.xda-developers.com/showthread.php?t=709135
Oh Yea
I searched USB HOST related topics but I did not find this one..lol
Anyway, I hope My thread could raise this up again..
Hopefully someone can put this function in.
power for usb drive
why cant the usb drive be powered via the audio jack. some clever devs have managed to power a 400ma led via the audio jack on an iphone so i guess the power can be taken from there. i think making a file explorer that outputs a continuous loud sound should do the trick. the cable can be made by splicing an audio cable to a standard mini usb to usb cable.
if it works we can at least connect pen drives without using any external power source.
please tell me how to enable usb on the go . i want to attached my pen drive and my hard drive to my phone .
plug it into the phone, and u're ready to go.. hence the name usb on the go

You need a USB Host to go cable - they are pretty cheap off of ebay.
USB hard drives don't always work - at minimum you will need a powered hub.

i know wht USB on the means but how do i enable it. i have tried connecting with a pendrive with the help of the USb on the cable but it does not show .
Once you plug your on the cable in the phone will inform you that usb connecter s connected. Whatever you plug in at the other end of otg cable work run unless it is not supported.

Just plug it in and look in My files. It will show as usbstorage.
I have an official samsung OTG cable, it works fine on the SGS2, but doesn't appear on the Galaxy Note under usbstorage.
Anyone else out there having similar problems?
i had grab some ebay OtG but after unmount and remove the OTG it causes wakelock which drain alot of juice.
I am also facing problems with OTG . when i plug in the cable thr is not msg nor anything happens in phone. please could any one tell me how to enable it may be with kernel or custom rom or may be anything else.
I also want to know this as well,I have spent considerable time yesterday trying to make this work but no luck at all,I would appreciate if someone could help,as I have seen a video in this forum where the guy was able to.connect a mouse to it stating that it is supported out of the box.
I was able to get it to work with a pendrive and a mouse with no problems, but I couldn't get a keyboard or my 2.5" external drive to mount.
Details:
My OTG cable was from DealExtreme for $2.30 or something.
My pendrive was FAT32 formatted.
My mouse was a basic $10 optical one.
My 2.5" external was NTFS, which probably goes some way to explaining why it didn't work even when I gave it some extra power from my desktop PC too.
My keyboard was a standard USB. I also tried a Logitech keyboard with a wireless USB dongle but that didn't work either.
I watched a whole film off my pendrive with no issues. I messed around with the mouse a bit, but the cursor moved too slowly for my taste and the scroll wheel didn't scroll webpages, which is half the reason I'd plug a mouse in anyway.

If you get no message when the cable is plugged in on it's own, chances are it is a problem with the cable. I bought a cable of Ebay which didn't work, so I bought a different one and that did.

Does the USB port have any other function other than power?
Don't think so, only power AFAIK.
I plugged it into my computer and even tried pressing and pressing/holding the button on the Chromecast but my computer didn't indicate any hardware plugged in.
I wonder if the data pins are even wired to anything internally.
UPDATE: The USB cable that comes with it may not work for data transfer, tried it with my phone and it didn't work. So I tried a normal microUSB cable but still nothing.

It has bluetooth... so in theory that could be a simple alternative... we just need to figure out how to access hidden menus.

I tried this with a self powered USB OTG cable, just to see if the Chromecast would blink, bing, or do anything to show recognition, no dice. Also tried booting with a USB drive in, no difference.

Examining board
Based on examining the photos of the motherboard on ifixit.com...
Component EM1 appears to be a USB Common Mode Choke. That goes on the D+/D- pair which you can see routed from the USB port, so it wouldn't be present if there wasn't some use for data communication over the USB port. (Cost sensitive equipment.) The flip side of the PCBA shows TP1-TP20 (Where TP19 and TP20 appear to be GND). My guess is in that mix you have a JTAG port for programming/testing the unit initially with a pogo pin rig (evidenced by the dimples observed in each of those locations), and there might be more high/low GPIO pins where one might allow the unit to enter its USB data mode.

Looks like its already been rooted. With what looks like a dual usb otg. They don't go deep into what specific cable but, I would guess it is a generic dual usb one off ebay, or amazon, heres a quick one i pulled from amazon http://www.amazon.com/Micro-Cable-P...8&qid=1375052489&sr=8-3&keywords=Dual+Usb+otg
But if you read into it, they say you can root, but unless your a developer you probably wont get any benefit of rooting....yet, if at all.

Please correct me if Im wrong, but the cable you linked only charges the thumbdrive/keyboard/mice/etc NOT the Chromecast so how would one root it since it does need power from usb plug? I've been searching for correct cable and cant find it; link to correct cable would be greatly appreciated!!!
This cable wouldnt work, right? http://www.ebay.com/itm/Usb-type-A-..._USB_Cables_Hubs_Adapters&hash=item4857e3608e

I own that cable from Amazon and it should work. It brings in +5v from a charger connected to the female microUSB port and then splits it to the female full size USB port and the the male microUSB port so both the USB host device and the USB peripheral device are getting power.

I also bought that powered OTG cable off Amazon and it will power the Chromecast as well as provide the means to flash the Chromecast via a USB thumbdrive. When you apply power to the Chromecast, it automatically flashed the bin from the USB drive. There was no interaction required (or even possible). Of course this was on the original firmware - if your Chromecast updated itself, you have lost the ability to root the device at this time.
Clearly the Chromecast does sense the USB drive and pulls data from it during the initial boot sequence. However I'm not sure if it would ever work for other devices such as keyboards or storage devices, etc.
I'm not sure why anyone would want to hook those types of devices up to the Chromecast however. Once you have root, you can telnet into the device, so adding a keyboard doesn't seem that important. The whole idea of the device is that you send it media from other devices and control it via that other device. Adding storage for example doesn't seem important since it can pull media off the network already (ie a NAS or another computer).
Anyway. That has been my experience with it so far. It's a long winded answer to more than just your question about the OTG plug.
I would personally love the ability to send audio out without having an hdmi TV be on through the usb somehow...
