Hey Guys:
Here is an old but challengable subject to discussion:
( before going to discussion I must appreciate GSM Coolhawk for his message on Modify any USB GPS to XDA Serial RS232, afterrnoon project and also chat with me)
XDA and many of other handhels and ppcs dont support SDIO. But we have ActiveSync Port that support USB and RS 232. However these devices act as a slave USB so we cant connect any usb prepherals.
IS it possible we use an "USB to RS232 Converter" to convert output signal of prepheral devices as a readable signal for ActiveSync port of XDA device?
Thanks
yes it would be possible
problem nr 1
usb1.1 is 12Mbit /Sec
usb2 is 480Mbit /Sec
old style serial rs232 is about 160Kb/sec
many a device would malfunction if it's return signals from the master were delayed that much
problem nr 2
even the usb to serial and parallel ports you can get for using on pc's are not 100% transparent and many devices have problems with them (usb to serial and parallel ment as in you connect old devices to your converter which connect to the serial port)
problem nr 3
drivers you would still have to write drivers for all usb devices you wanted to use unless the manufactor already had the same device in a serial version and therefor a driver which would control it using rs232
so yeah it's possible
not really worth it imho
and as a replacement for the lack of a SDIO it would be easier and cheaper to buy a new device

Is it or will it be possible in the future to connect a USB harddisk to the XDA II. There seem to be a few possabilities for it. But are any of these workable.
It would be great to hook up a 120 GB Harddisk to it especially in your car for PDF files, Tom Tom maps and lots and lots of music.
I have listed the possabilities that seem to be around please feel free to comment.
1. The XDA II has a video chip which supports IMAGEON 3200 USB On-The-Go ( designed for mobile interconnectivity by allowing a USB device to communicate with other USB peripherals (such as printers) without the need to go through a PC). Would it be possible to use this chip to connect to a USB hardisk.

2. Buy the expanssion pack and a "Dual Port USB Host CF Card" this would propably be the only working system at the moment.
3. There are already bluetooth > USB printer units on the market that allow USB printers to interface with a PDA using bluettooth. There does not seem te be a Bluetooth > USB host interface. :?:

ah you also saw the cf adapter ;-)
i was hoping they also could make an external version, so we can connect through the connector.
mabe we can hack it ;-)
i think the cf card only uses, power, and usb in and out data transfer
There are specs from transdimension in this pdf file, don't know if it is the same chip as in the XDAII

I was notice the USB OTG function in the ATI IMAGEON 3200 chip.
if the OTG function pins was connect to the CPU and layout on the PCB,
It is maybe add the OTG function,then we can use USB devices like mass storage drivers,HID drivers,Printer and so on!it enjoy!
If i remember correctly, the XDAII does not use the Imageon chip to provide USB, but instead uses the XScale processor (or was it just a seperate chip... I forget...) which does not support OTG, only USB slave.
As such USB OTG is not supported by the XDAII, so unless you can find a USB harddisk which does something clever to allow the harddisk to be the master device, this can't work...
Am I being Daft
I have been trying to solve this problem for a whhile (in a non technical fashion of course).
I synch my MDAIII with my PC but in the near future I would like to be able to save work from other peopls computers to my device and vice versa without the need for cables and cradles.
I have seen some usb pendrives that rather than actually containing memory as such are actually sd card readers (and other cards too). It looks like it would be quite simple to remove the sd card from my MDAIII and pop it into the pen drive reader' and plug it into a computer and vice versa.
Is this too simple - am I missing something and being dense or is this a viable possibility. If it is - its very cheap - it would cost me about £4.50! ???
Can anyone help me out here?
Hello,
I looking for a cable to add a serial port (RS232) on my P3600.
Do you know if this kind of cable exist ?
Thanks
Currently not possible - the P3600 does not have USB host capability which is required to work with any of the USB - serial adapters out there.
The P3600 allegedly has USB on-the-go (OTG) capability which is a new way of enabling peer-to-peer USB connections. However currently there are no drivers for the P3600 to enable this capability, and in any case no OTG capable USB-serial adapters...
Currently the only real solution would be to use a bluetooth - serial adapter - these do exist but are relatively expensive.
Hello everyone,
I am taking networking classes and I was wondering if it's possible, instead of carrying a laptop with me, to use my SGS2(rooted) to configure switches/router with.
I bought a female to female usb adapter, and i also have a USB to serial cable. So all the cabling is fine, but still when I open a console emulator i get nothing going there...
I believe it may be parity related, but there seem to be no console parity settings on any of the terminal emulators that i was able to find on the market.
Usualy, if you extablish a console connection from a laptop via USB, the usb port gets defaulted to COM3 or COM4. Do android devices have a defaulted COM port to the usb connection, Is there a config file where I can change it, or is it supported at all?
any help would be appreciated,
thanks
Hey, I'm trying to figure out how feasible it would be to connect a high powered usb wireless adapter that supports packet injection (Alfa AWUS036H) to my Xoom for some wireless kung-fu.
If I can find or hack up a cable to even connect the adapter to the small usb port would it be possible to interact with it and possibly port or even write a driver for it? If so, how non-trivial would it be, is Android driver development documented somewhere or does it need some secret magic sauce?
Hi, is it possible for Android to connect to other pc just like Windows do in this pdf?

You can set up Android PPP over USB by means of ADB.
Look inside here:

But will this work also on serial connection?
USB stands for Universal Serial Bus.
Bandwidth of standard Serial is 115 Kbps, whereas bandwidth of USB 3.0 is 5 Gbps and of USB 2.0 is 480 Mbps.
Wondering why you want to connect over standard Serial?

As other device only have a serial port, I may need to use a converter plug to connect to it. In this case I may need to set the baudrate, purity for the connection
