RaspberryPI IrToy - restore /dev/ttyACM0 interface in newer kernels
Raw
kludge_cdc_acm_irtoy.sh
cd /lib/modules/`uname -r`/kernel/drivers && \
mv -n media/rc/ir_toy.ko media/rc/ir_toy.ko.DISABLED && \
mv -n usb/class/cdc-acm.ko usb/class/cdc-acm.ko.DISABLED && \
env -i sed -e 's/\xd8\x04\x08\xfd/\xff\x04\x08\xfd/' < usb/class/cdc-acm.ko.DISABLED > usb/class/cdc-acm.ko && \
depmod -a
# reboot after doing the change.
#
# This changes blacklisting of USB ID `04d8:fd08` in cdc-acm, so IrToy gets recognized
# as it was in previous kernel versions, and `/dev/ttyACM0` gets created for it instead of `/dev/lirc0`
# For those who don't use lirc but IrToy directly and so need compatibility with that...
#
# works at least in Raspbian.org Buster raspberrypi-kernel 1:1.20211029-1~buster armhf
