Develop Bugs

I am going to build USB port,need help.

Well guys,i am going (me and other guys who have good experience in e-circuits)to try build a USB port to the Himalaya..
Now I understand by the http://wiki.xda-developers.com/wiki/Connectors link that only the large connector have the pins for USB..
During this time,any help,new informations about himalaya's USB will be appreciated.

In fact the project "USB port" is actually at level zero. (really busy previous week)
I am trying to make this to connect especially a Mouse to XDA2
So,I really need a help from you,MattM and others..
Can someone build or convert a generic windows mouse driver to pocket pc?
Or maybe is more easy to make a serial connector for mouse?
Then does we need a pointer?
-Is this factible? or just a dream?
(Laucher Prog based on Flash like PocketWin has a Pointer add-on)
Waiting for your replyes!
Regards,Ser

i read something about it in this forum, try searching for home made keyboard or mouse & you might find some answers to the basic questions

Come on guys!
I will use the DC adapter connector and USB female connector.(You can see the photos attached)
-But first explain me closely about UDC- and UDC+ does they are for data transmission or power?
Also USB_VDD is for?
-If I connect a USB device to the XDA2 does it will give power to it?(for mouse,etc..) or do I need to connect an external power alimentation? If yes,6V?
-If I build a Serial port can you explain more about:
RS232_DCD
RS232_CTS
RS232_TXD
RS232_RTS
RS232_RXD
RS232_DTR
Maybe is simply make the serial cable like on the "Connector's Page" (http://wiki.xda-developers.com/wiki/Connectors) and attach a serial Female-Female to connect Mouses and others?
Please post your comments,suggestions,ideas.
Regards,Ser.

UDC- and UDC+ are data
USB_VDD is for power
I don't think anyone yet knows if the XDAII can work as a USB host anyway.
For rs232 you will normally only need RS232_RXD, RS232_TXD and ground.
I'm sure someone did a serial mouse program before....
Jamie

RS232_RXD, RS232_TXD are for data?
I hope someone did the program but i've searched over i-net and didn't find anything about it!
I've also read about the built-in USB port of Toshiba,some people connected their HDD and all went perfectly.
So,I hope connect a mouse will not be so hard..
Regards

Have a look here for a mouse driver http://www.windowsfordevices.com/articles/AT3401319437.html

Yeah,i've seen it before but don't sure if it will function properly,but let's take it for that moment.
Thanx!
After a short search over i-net I found the prog. that uses Toshiba for its serial devices like mouse,keyboards: Click n'type and Point n'type..let's figure more about.

OK,now I will connect the female usb to the connector like:
RED (USB_VDD +5V) to Pin 13
GREEN (UDC+) to pin 14
GOLD (UDC-) to pin 15
BLUE (GROUND) to pin 16
Correct me if it isn't.
But I can't find a scheme of the connector that I will use,I can't understand which is the pin 1..2..
Can someone give me help about?

Thanx to RUDEGAR that provided me the link,http://www.deje.gmxhome.de/software.html
I have the USB drivers and pointer for Mouse,also support for Mass storage.

i have disambled this connector 2 times
let me look it up for you
[UPSIDE]
[1] [5] [9] [13] [17] [21]
[3] [7] [11] [15] [19]
---------------------------------
[4] [8] [12] [16] [20]
[2] [6] [10] [14] [18] [22]
[DOWNSIDE]
now the upside is when you hold the connector flat and you see the 2 cutout lines in the plastic wich goes into the xda
topleft from that is pin 1

Well,the cable doesn't work! :x
-XDA2 does not give power to the usb device (tryed with a optical mouse)
(N:we verified with a VoltMeter and all cables seems to be ok)
-Also the DeJe Drivers (originally built to Toshiba) don't work. But the driver's are compatible with all WM2003 OS..
-I verified that on my pc(Win XP) when I connect the Optical mouse,it will no give power to the device once it load the drivers,so I guess maybe the same on Pocket Pc?
What do you think about?
-Probably I will build a Serial Cable for the Mouse
Regards, Ser

have you tryed a usb pen yet.. I see you mentioned storage before

yes,in fact I have't installed the Mass storage drivers for a Pen Drive,etc..
But I verified that no led (on pen drive) and no optical light was lightening so is easy to understand that XDA2 don't gives power to the USB devices... :?:

would they light anyway ? do they only light when the correct drivers are used and its told to light. I think it would be a awesome idea to add usb to the xda.. you could then use it for loads of other things..

It cannot work. Never will.
There are two different types of USB devices: hosts and clients. You can only ever connect a client to a host. Connecting client to client does not work. It's a bit like two people picking up the phone, none of them dialing a number, but still hoping they'd get connected. Not going to happen.
All USB mice are USB clients. The XDA II also is a USB client. The USB chip in the XDA II can only handle being a client. It does not support host mode, so no software in the world can change the XDA II to a USB host.
So, connecting a USB client to an XDA II will never work.
For serial communication (RS232), there is no such problem, so it may be possible to connect a serial mouse to the XDA II. The first thing you have to make sure is that the voltage is correct. "Normal" RS232 uses +12V/-12V, whereas most small devices (and quite likely also the XDA II) uses 0V/5V. You may have to add a MAX232 (or compatible) level shifter chip to your cable.
I strongly suggest you search the 'net for RS232 and read as much as you can find. If you just experiment with cables without really understanding the implications, you might damage your XDA II.
Once you sorted that out, make sure you connect all the handshake lines your mouse uses. I would imagine that some mice may need at least the DTR line assigned before they will start doing anything.
After that, the rest is software. Your driver will have to a) pick the correct baud rate, b) drive the handshake lines correctly, and then c) it can start receiving data.
Good luck!

well there are CF cards which have usb master support
and with the backpack the xda2 can use CF cards
of cause the driver issue could be troublesome and i'm
not sure about the speed dec going that interface to interface way
but i would not rule out that it could work
with the right drivers mind you

How about connecting a serial to USB convertor to the serial port on the XDA II?, surely that would leave you with a USB host port that you could plug a mouse into?

In this case is more simple to connect serial mouse to the serial port.
Dunno if how u tell the usb will work.. :?:

Would this do the trick?
It says host ports, can the XDA2 handle it?

USB HOST for pocket PC ????

Hi
i am sure for alot of people out they have searched for something to make their usb devices work on a pocket PC. i have gathered some information with regard to this topic and i hope that other users will add to it so that there is a greater awareness and mayb it will help someone figure out the best way to create 1 for the PPC
right now the there is no external USB host controller for pocket pc.
the reason we need the USB host is so that we can connect external USB devices. but i believe that we also need to load the drivers for devices as well.
wat i think is the way the device should work is the usb host for ppc should have drivers built into it so that when u connect a flash drive for example it can identify it and then send the necessary info into the PPC so that the PPC will then handle it in the correct manner. thereafter on the PPC we will probably find it as an additional drive.
I think that connectivity will actually work via the SDIO and not via the USB port.
If there are any other senior members that can elaborate on this it will be great, it will shed some more light on this feature.
I personally would love to have this feature, not for any specific external device but just the ability to have interoperability with all my usb devices onto my PPC.

there are usb host CF cards i believe
not sure if anybody ever made to test in a himalaya backpack which have a CF card
thing with usb devices is that usb mass storage one 1 generic driver
so one for external hd's sdreaders and usb keyring would be enough

CF USB host
Hi
http://www.ratocsystems.com/english/products/subpages/cfu1u.html
do you think that it can be converted from CF to SDIO ?
I actually searched for a CF to SDIO converte but no luck, however even if i do find it what are the chance that it will even work!!
anybody knows more about this ?
reo

it could easy brake because of the size diff
another problem is it would require 2.5watt to power a usb host
not sure if the sd interface can provide that kinda power at all

ok, but considering that we can overlook these obstacles will the converter actually allow for the CF USB to work ?
do you no where i can find a CF to SDIO converter ?
Ridi

I've got a question about "USB Host" as well... I read somewhere, that some processors are capable of USB Host but the companies didn't do the wiring in their devices. and of course the drivers are missing in Win CE.
So my question is: Can I connect USB-Devices to my PDA if I build a USB-wire where I inject 5V from outside and run linux on my device with USB-support built in the kernel?

RS-232 for Serial Access

Hi there,
I was searching the forums for an RS-232 for serial access and can't find any information as I was wondering if there is a RS-232 cable avaiable for serial access. Like the cables RS-232 to USB converter for laptops to config cisco, juipters and Huawei. I have a RS-232 to USB but it is using a regular USB A plug. So the other question is that is possible to use the regual RS-232 to USB converter with gender change, but I don't think there are any drivers for the accessory for WM6. So it sounds like I have answered my own question . BTW, I am using the Kasier and it would be a great help if I can buy one instead of DIY one like -> http://forum.xda-developers.com/showthread.php?t=257858
Kengie

would believe it is required for such a device to work that the pda support usb host only Athena does that

Thanks. I though that the Kasier has the OTG (yes it does), but you are right. It doesn't support the USB Host features. Thanks.

if you by OTG mean usb on the go then htc dont seem to use that feature in any of their devices even if the cpu have it included it seems they use their own usb chip

How to transfer pictures from camera to phone

I have a problem, that I hope someone here can help me with.
I have 2 devices, a digital camera and a phone:
- Canon Powershot G10
- HTC Touch Diamond
The Diamond is capable enough that I don't always need to take a laptop with me when I am travelling. But I still need to transfer pictures from the camera to the internet. The phone can upload to the internet if only I could get the pictures onto the phone! So I want to find a way to transfer selected pictures from the camera to the phone *without* using a computer.
As I can see it, there are several different ways to go about this, but I haven't found a solution yet:
1) Find a device similar to the iPod Camera Connector that would let me connect the camera to the phone via USB. Note that it is not enough to have a device that copies all photos. I need to select which photos will be copied. Copying 16GB of pictures onto the 4GB phone is not an option.
2) Find an SD card reader that can connect to the HTC Touch diamond directly.
3) Find a bluetooth adapter for the camera that will allow file transfers.
4) Find some way (hardware and/or software) to make the phone work like a PictBridge-compatible printer, so that I can "print" selected photos from the camera to the phone.
5) Find some software and/or hardware that will make the phone work as a USB host. If that was possible, reading SD cards is trivial.
I have searched and searched for solutions to this problem but so far without a result.
Needless to say, the solution needs to be both cheaper than a laptop and especially smaller and lighter than a laptop. Otherwise I could just bring a laptop.
I hope someone here can help me realize the full potential of my HTC Touch Diamond!
Best regards,
Mikkel

without usbHost nothing can make the usb connector in the diamond be
and activeparty
it can interduce itself to the camera as usbMasstorage but can connect itself to anything
so your camera would have to be the activepart no matter if you PictBridge, sdcardreader or iPod Camera Connector
the extUSB on your device is miniUSB input only when usbHost is not supported
plus audio out

Thank you for your reply.
As far as I know, neither the camera nor the Diamond has the capability to act as a USB host. Connecting them directly is therefore probably not an option. That is why I listed the various things that I have thought could go inbetween.
The iPod camera connector is such a device: a device that can connect 2 USB clients to each other. Unfortunately it only works on an iPod (as far as I know). I believe it may be using the USB OTG standard.
I know that a standard USB SD card reader requires a USB host to connect to. That is why I was hoping to find a non-standard SD card reader specialized for use with Windows Mobile phones or HTC phones. There is no doubt that it is possible to make such a device - I just don't know if anyone has done it. It would be useful for many purposes.
Here are some devices that come close to what I want to achieve, but not quite:
http://www.usbgo.com/
http://www.cooldrives.com/usb-otg-adapter.html
The main problem with these is that I don't see any option to select only a few photos to transfer.
So I was hoping that one of the knowledgeable people in here knew of a solution.

doubt any cable it do it as the cable it would have to init the usb connections to both devices and handle which files where to be transfered from to where
that would prob require the cable to have a screen and input option which would
pretty much make it a compuer or a pda with usbHost
my bet is that ipod have usbHost otherwise it would never work
unfortunaly the many posts in the forum about usbHost include as many hits about
usbToGo
and as much or little success

Connect a Usb host device with the camera
Hi.
Do you know how I can connect a digital camera with a device that has usb host. I own a X7501 with WM6.1. I was looking for a solution to transfer my digital photos taken in my 7 MP Sony Digital Camera to my HTC, in order to send it by mail.
Thanks for any suggestion
Regards

yes Athena is one of the few htc devices which support usbHost
http://forum.xda-developers.com/showthread.php?t=334024
it should work just fine if the camera support usbmass stroage
otherwise it require a driver for the camera
also you may have to use a cable which get power from somewhere else
then the Athena as it may not able to provide enough power

Searching for a solution!!!

Hello.
I try to connect my camera to the Athena, using the 4 in 1 cable adapter, It ask me for a driver name. I couldn't get anything.
Also I try to connect it via the docking station that has two usb ports for the USB HOST, in these I can connect a mouse and a keyboard. Also it has an external power, but the camera did nothing at all. I try to use all the connection mode that the camara has.
Also I try that some other recomend in this thread: USB Driver for Digital Camara.
I made a lot of search. Did you know somebody that can help me.
Regards.

you sugest you ask in the Athena forum
or pm some of the people who wrote in the
thread i linked to
as I don't have any first hand exp with Athena's or using usbHost

You can actually buy SD to Micro sd adaptors. I have one, they work really well.

Thanks a lot for your tip.
I'm trying a USB card Reader, but I'm looking for a solution that let me use the 4 in 1 cable, in order to carry the less of thinks with the me.
Right now I'm using a little bag with all that I use.

simple answer
Get a micro sd card that has an SD adapter. Plug the micro sd card into the sd adapter and plug the sd adapter into the camera. Take your pictures. When you are ready to email pictures, pull the adapter out of the camera, remove the micro sd card, and plug it into your phone. You are ready to email pictures. Keep things simple and just carry the micro sd adapter and forget all the cables and stuff. A spare card is always handy, too.

Second USB device

I tried connecting a USB keyboard using an USB OTG cable, but I didn't get it to work. The other USB port is in use by my external harddrive.
Is there a possibility to make the keyboard work?
Can immagine more people want to add a second USB device to their OUYA...

You'll need to buy a USB HUB (Get a powered one to future proof all your USB needs, you can get a USB 2.0 Hub pretty cheap). This will allow you to hook up at least 3 USB's to the OUYA. The Micro USB won't work for things such as hard drives or HID devices.
In the future, please use the search function before posting as this has been talked about in many other posts.

I have a 4-port hub and it works fine connecting 1 storage and 3 other usb devices

I had this issue where only one harddrive could be used and If you have a harddrive with 2 partitions ouya wont mount it. Luckily I found an app called usbotghelper which does all the above I mentioned plus read and write and ext3 support. I wish it would get submitted to the ouya store so I could use the paid version that will mount on startup.
