Failed to open device /dev/usb/ttyUSB0: No such device
 
hello, i want to use my irda adapter, and i have to type #irattach /dev/usb/ttyUSB0 -d ma600 -s
but there is error saying Failed to open device /dev/usb/ttyUSB0: No such device
i look into /dev/usb, and ttyUSB0 does exist. so, how can i solve this?
the same thing happens when i try to #setserial /dev/usb/ttyUSB0, but if i do it other than root account,
the error would be /dev/usb/ttyUSB0: Permission denied.
please help me...

You probably need an entry in fstab with the user option set if you don't want to do it as root.

thanks for the reply. well, the irattach must be run as root. but when i run as root, it says that it failed to open ttyUSB0, even though the ttyUSB0 does exist. please help if you have
any clue, thx.
