gumstix

It seems the gumstix need to be powered up already with the hub connected.

Subject: [Gumstix-users] Xbee module : Unable to enumerate








Hi,I'm trying to use the Xbee - Pro with the Sparkfun Explorer board (FTDI adapter) on Tobi. It was not reconizing so I installed libftdi.Now it shows the message "unable to enumerate USB device on port 2" and the is still nothing under /devThere is something else I must install ?
I don't think its a matter of power since I tried with a powered hub.
Thanks

The Xbee device appear as /dev/usbdev*.* instead of /dev/ttyUSB* .Can I open this as a serial port as I do on a PC?I'm having trouble to do this and I believe this has something to do to the group of  "usbdev" beeing "root" and not "dialout" as it is on the PC.
Somebody has an idea what can I do?

Did you check that you installed the "VCP" driver (ftdio_sio) and not the D2XX library. (libftdi) I think you want the VCP driver if you wish to 
talk to it via kermit or using open() calls. Otherwise I am guessing you need to use the API which is part of libftdi library.

Yeah, I had installed the libftdi, and it didn't worked.But now when I load the modules "usbserial.ko" and "ftdi_sio.ko" it does appear the devices ttyUSB* and it works to use open(), read() and write().By the way, how do I put modules to be loaded automaticaly on boot? 
Thanks,

Put module names in /etc/modules, one module per line

man modules for more info.

Hello Mathias Kriebel. 
I have to do the same thing, but with summit. Where did you find the driver
"usbserial.ko" and "ftdi_sio.ko" ? 
Did you met any problems in Xbee and gumstix communications ?
Is there any open-source stack which is already ready to use to establish
communication between gumstix and xbee ?  

Thanks for your help, 

ikuzar

maybe I missed a part of the thread, but why would you not use one of 
the RX,TX pin combos on the summit? I use a serial adapter with my XBee 
and just connect it that way. Not at the office in front of my UAV stuff 
to remember exactly the 2 pin numbers, but figuring that out should not 
be that hard. I only use the USB adapter boards for use on a 
laptop/groundstation.
