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?

Bluetooth enabled IDE peripherals... possible?

Hi guys! I don't know if this thing belongs here, but since I'm an owner of a Blue Angel device, I'll put it here anyway. Is it possible to create a simple device which has the following components:
- An IDE adaptor (don't know if this is the right term, but what I mean is a cable which can be connected to standard HDDs', CDROMs', etc.)
- A power input to provide external power to the HDD or CDROM connected to it.
- A bluetooth radio allowing a device (PDA, cellphone, laptop) which is bluetooth enabled (like my Blue Angel) to connect to it via bluetooth. I think the directory bowsing profile, or network profile should be supported.
The purpose of such a device is to allow my Blue Angel to read CDs' and copy data from hard drives. I know it would mean carrying an extra device, but considering the advantages it would give me (reading CD's and HDD's without the need for a PC) I would surely consider adding it to my gadget bag.
Does such a device exist? If not, is it possible to make something like this?

Sorry, but it can't be done. The Blue Angel's USB port is only a USB Slave port, meaning it only works if plugged into a computer.

I dont think a bluetooth drive adapter exists, but maybe something wireless could be used??
e.g.

I would also suggest WIFI. Bluetooth is way too slow

Toshiba used to sell a Bluetooth hard drive called the "HopBit". I don't think it was ever sold in the US but Dynamism imported it for a while. It seems to be discontinued though.

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

[Q] ???Remote Screen/Display Solution???

Hey Guys,
I need your help. I currently have a carputer running Windows XP in my car now with an 8" touchscreen interface. It works and does what I want it to but I'm thinking I want a cleaner solution. At first, I was thinking about loading Android onto it but then I was thinking I could probably go one step further. My EVO does everything I currently have in the car (nav, music, video, etc) and it'd be awesome to use my EVO as the CPU if I could get it working with a bigger screen. Is there some kind of device on the market that acts as a remote display/screen that allows seamless touchscreen functionality? I'm talking about mirroring the display of the EVO. Like via bluetooth or HDMI out with USB interface for the touchscreen function?? That would work so much better because all I would have to do is mount the screen and run power to it. I could completely remove all of the computer hardware saving space and points of failure. It'd be best via bluetooth that way I wouldn't even have to take it out of my pocket. If there was a way to get it to work with the HDMI port for the video/audio feed and the micro-USB port for the touchscreen interface, I could just run a dock in the car and work it that way. If anybody knows of a device or a solution that would accomplish this, PLEASE let me know! If you think you have an easier/better idea, please feel free to share that as well! Thanks!
-Greg

I know there are several developers on the brink of completely unlocking the HMDI port functionality so I know it can be accomplished...but getting the touchscreen to be seamless I think would be the most challenging part...

Ok, so after changing some search terms, I was able to find something similar: Mimo USB Monitor. The entire monitor (power, video feed, and touchscreen interface) is though one USB connection. I came across this XDA thread that pretty much explains how it could possibly work: http://forum.xda-developers.com/showthread.php?t=898418 Has anybody done any research on this or know anybody that has or is currently working on something like this??

Any ideas??

That wont work. The usb port does NOT do video out. Your only option for video out is the hdmi port, which as of right now, will only output video and pictures. As said above, there are dev's working on full hdmi output, but who knows when it will be available.

That monitor is a standard USB DisplayLink device. No special video out needs to be on the port, you just need a device capable of operating as a USB host with the correct drivers loaded (which are open source on normal Linux and thus should be portable to Android if someone was so inclined). Thus, any phone which could be used with a USB keyboard, mouse, thumbdrive, etc. can support that monitor.
That said, I've looked a few times and do not believe the Evo has USB-OTG support and it certainly does not have a standard host port, so we may be SOL there. N1 users can do it for sure, I'm pretty sure I've seen it used with an Ubuntu install, creating a kind of hacker's version of the Altrix around a year earlier.

Alternatively, it's not the fasted method, but there are a couple of software solutions that basically let you VNC to your EVO from the PC. androidscreencast is one (google that phrase, can't post links yet) but it seems as though it's stalled out. I think that Droid Commander (or something like that) also has a screen casting option. This way you don't have to worry about touch screen drivers etc.

I wonder how a cheap chinese tablet with a usb host would work.
I've considered just installed a cheapo tablet in my car then go out to rca's or a bluetooth transmitter. My line of thought on is most headunits/music is only stereo(2 channel), so you wouldn't lose anything there. The two big problems I forsee would be a reduction in the the output quality using 3.5 to rca and finding one with a fm radio thats worth a damn.

Well if you really wanted to go a tablet route. there is the smartq v5 you can pickup for around 250. it has full hdmi out usb host bluetooth and hardware video decoding (1080i hdmi video looks soo nice on a tv form it). You can download the android 2.2 firmware and run rocketplayer for allmost any video.
