udev rules error on BBB

ramanc51

Hi all

             In my BBB i written udev rule 99-usb-serial.rules at /etc/udev/rules.d to fix my usb-serial converter ttyUSB0 name as static(e.g printer), but this rules not create symlink as i given below, alos i saw error that unable to open '/sys/udev/ttyUSB0', is there glue to resolve this error?

 

my 99-usb-serial.rules

 

SUBSYSTEMS=="usb-serial", MODE="0666", ATTR{idVendor}=="0403", ATTR{idProduct}=="6001", SYMLINK+="printer"

 

Error

parse_file: reading '/etc/udev/rules.d/99-usb-serial.rules' as rules file

udev_rules_new: rules use 197880 bytes tokens (16490 * 12 bytes), 32369 bytes buffer

udev_rules_new: temporary index used 60680 bytes (3034 * 20 bytes)

unable to open device '/sys/dev/ttyUSB0'

debian@beaglebone:~$

 

Note:

        But i am able to open this device as /dev/ttyUSB0 only by my another java application on same BBB, but not as a printer

    Mike, VID&PID is belongs to my device, by the guidance on other sites that are referenced i came up, for command ls -l /dev/ttyUSB0 i found the device info is stored in /sys/dev/char/188.0, the result for above command is given bellow, are you telling my udev rules is not correct?
