been trying to use a rs232 device that uses the usb port. it calls for a virtual com port to be created. i am running on ubuntu 10 and get hella confused with the search results i have come across.
some call for the usbdevfs which apparently doesn't exist under lucid. another had me do use some "magic" in getting it to work. they provided a script mountusbfs.sh
# Magic to make /proc/bus/usb work
mkdir -p /dev/bus/usb/.usbfs
domount usbfs "" /dev/bus/usb/.usbfs usbfs -obusmode=0700,devmode=0600,listmode=0644
ln -s .usbfs/devices /dev/bus/usb/devices
domount --rbind /dev/bus/usb /proc/bus/usb
of course when i tried it the domount command doesn't exist so i modified the above script replacing the domount with mount and it seemed to do something things.
usbview is specified as the determining factor whether or not you have the usbfs mounted properly. it wants to use proc bus and ubuntu doesn't use that anymore apparenlty.
need a serial to usb port
a com1,2,3 or 4 to be created.
i have read that i need to enable a usbmon (flag?option?) in the kernel to be set. which it isn't when i followed the steps to check.
