Question How do you Point to a USB Device??


I have MDK 9.0 and i need the location of one of my usb ports for a program
The default port (serial i think) it is set for is /dev/ttyS1
I need to change the ttyS1 to the location of a USB port.

in /proc/bus/usb/devices i got this

Ive looked around in the /dev directory and can not find any clues to what any of the USB's would be called.

someone help me figure out how to point to a USB device?

I'm guessing here:

Do you have a USB MODEM? It might be /dev/ttyUSB0. Verify the usbserial module is loading?

See www.linux-usb.org for support info on your device.

My USB ports are listed as /dev/ttyUSB0, /dev/ttyUSB1 and so forth.

To get my palm pilot working, I had to create a symbolic link to this, as Ximian insisted on using a serial port for it. I had to fiddle around with which USB port it actually was, though, before it would work.

If it is a usb mass storage device (compact flash reader) the device will be /dev/sdax
x = nothing, 1, 2 etc...
