Obscure USB-serial adapter
 

Hi there. I'm trying to connect a mobile phone (Sony-Ericsson K700) to my PC. Most SE phones communicate with the PC via a USB-to-serial cable adapter known as the DCU-11, and fully supported by the pl2303 driver in Linux.

But, since i'm cheap, i didn't get mine from Sony-Ericsson, and instead bought some work-alike in a flea market. And it doesn't work. Once plugged in, here's what 'cat /proc/bus/usb/devices' says about it:
Now, what's with that vendor? It isn't even listed on http://www.linux-usb.org/usb.ids , which looks pretty up-to-date. And googling around takes me to the Ark Pioneer Microelectronics, which is in chinese.

Anyway, i think it might work with the same pl2303 driver just fine. Only trouble is I can't convince pl2303 to take it!!

My first attempt was "modprobe pl2303 vendor=0x6547 product=0x0232", but the driver doesn't support that.

Any ideas?

Hi:

I have a cable with the same chip for the Sagem. Have you had any luck yet?

Paulo

Unfortunately no. I hacked the pl2303 driver included with the 2.6.13 kernel, so it's now recognized and taken by it when plugged in. Then I tried using gammu and minicom to communicate with the phone, but had no success: minicom says it's offline; gammu --identify times out waiting for an answer (with the connection set to at9600 in the ~/.gammurc, of course).

I'd look into the windows driver, but currently i don't know how to test the cable when nothing is plugged in. Any ideas on how to test it?

This Sane site http://www.meier-geinitz.de/sane/misc/develop.html has some info and links on how to understand how a usb driver works under windows. I might try some of the tips. Perhaps it might help you too.

I am also looking for solutions.....I just use that cable for connecting serial console like Cisco device.

I got this device working (which is imho an ArkMicroChips device)

try inserting usbserial module with:

# modprobe usbserial vendor=0x6547 product=0x0232

this will create the appropriate /dev/ttyUSB0 link and you can work with that device from now on

Hope this helps?

I have the same problem (ArkMicroChips device) trying connect nokia cell phone

Configuration:

mknod /dev/ttyUSB0 c 188 0
modprobe ohci-hcd
modprobe usbserial vendor=0x6547 product=0x0232
modprobe pl2303

dmesg |grep usb
usbserial_generic 1-2:1.0: Generic converter detected
usb 1-2: Generic converter now attached to ttyUSB0
usbcore: registered new driver usbserial_generic

usbcore: registered new driver pl2303
drivers/usb/serial/pl2303.c: Prolific PL2303 USB to serial adaptor driver v0.12

but when i try to identify phone using gnokii the connection times out
Does anyone know how to use this cable under linux?

Hi

Can you please provide the complete steps.

Regards,
Sachin.

hi all,

have you already figured out how to use the cable on linux?
i cannot even pass the vendor, product params to it - it gives me an error... :/

i tried recent kernel (2.6.15) and still nothing... has anyone tried the driver shown above? how to compile this thing?

------

EDIT: I tried compiling that c file as a module, but no luck (bunch of errors from gcc) - any ideas?

------

EDIT2: Ok, looks promising.

What I did is:
0. I took the code from post above and inserted it into a *.c file.
1. grabed from my current kernel sources the usb-serial.h and copied it to my working directory.
2. created Makefile (yes - that's the name of the file) in working dir and edited it as shown on this site: http://www.captain.at/programming/kernel-2.6/
of course replace the sum-module in the example on that site with the name of the file you inserted the c code into.
3. run 'make' in working dir and you should get a compiled .ko kernel module.

now test it with insmod filename.ko - it worked for me, dmesg:

drivers/usb/serial/usb-serial.c: USB Serial support registered for fxusb
fxusb 4-2:1.0: fxusb converter detected
usb 4-2: fxusb converter now attached to ttyUSB0
usbcore: registered new driver fxusb

you can copy that to /lib/2.6.xx/kernel/drivers/usb/serial/ and run your update modules script (in my case this was modules-update or something...)

Thanks for the fix krisfx.

thanks,
Bartek

Hi Bartek,


Thank You. Your procedure worked!!.
But my phone is still not getting detected as modem

Regards,
Sachin.

I am having problems with gnokii as well - hope this is not the cable thing. anyways - I havent got much time to spend playing with this, maybe later...

Regards
Bartek

can't build the code... any ideas?
 

celafon, I'm having a bit of trouble with the procedure you outlined. I'm afraid I'm not much of an expert at these things -- any suggestions that folks can offer would be much appreciated. I'm working off of 2.6.11-1.1369_FC4, with the source RPM installed according to the instructions found at the following URL at mjwired (DOT) net (sorry for the ridiculous syntax; linuxquestions won't let me post real URLs):

/resources/mjm-fedora-fc4.html#kernelsrc

But I'm not having any luck building krisfx's code. The error messages I get when I run make--

Any help would be *greatly* appreciated.

SMBA44,

Try upgrading your kernel to 2.6.15 or 2.6.16
That should get the driver to compile but the fxusb driver posted but I still couldn't get the driver posted above to work with the ArkMicro adapter I have.

Thats what Ive got - arkmicro. I used this driver in windows - and it found the usb thing. unfortunatelly even on Winblows I cannot get this to work with my nokia 6100... I know this model has infra red but I need to plug in to pc permanently to make an sms gateway :D
