errrr how do I know which USB post my device use?


I need to know which usb port my palm device uses. I have four usb ports but I don't really know their order. I checked out my /dev and I have tons of /dev/ttyUSB*


so is there a way for me how I can access my palm device?

thanks

Open up a console, run this and then plug your device in, should tell you somewhere in there
Code:
tail -f /var/log/messages

I'd take a stab and say port 2, plug it into a couple of different ones and see which part of the output differs

usbview (gui)
http://www.kroah.com/linux-usb/

usbtree (command line)
http://www.linux-usb.org/
navigate to tools then usbtree. it's a perl script. just download then chmod and execute

or if you are really hardcore
cat /proc/bus/usb/devices
(this is basically that what the tools above do, they just have prettier output)

You might want to investigate using udev to customize the device name. Here is a decent rule writing guide to help you get started, but the basic idea is that hotplug can recognize the USB ID number of your palm device and then create a device in /dev that you named in udev. For example, if you always want your palm to be /dev/palm rather than /dev/ttyUSB?, you write a udev rule so that when hotplug sees that devices ID number, it creates /dev/palm. Basically, udev allows you to customize the /dev naming conventions so you don't have to go hunting for your devices. I've used it quite successfully with a digital camera and a USB memory stick.
