Problem
I got below error when I run the Test script. Although Parallel port is enabled in BOIS Settings.
rmmod: ERROR: Module plcm_drv is not currently loaded
insmod: ERROR: could not insert module plcm_drv.ko: Input/output error
Please do as follow
1. Make clean
2. Type “cat /proc/devices” and check if number 248 is already used by a device.
3. If so modify the “plcm_drv.c” file and change the device number to which not already used.
For example : I changed it from 248 to 255
5. Insmod plcm_drv.ko
For example : I changed it from 248 to 255
