I have also compiled LIRC with only usb_uirt_raw support and started 2 instances of the LIRCD servers with the following command line:
- Code: Select all
lircd --device=/dev/ttyUSB1 -o /dev/lircd1 -P /var/run/lircd1.pid -L /var/log/lircd1
lircd --device=/dev/ttyUSB0 -o /dev/lircd -P /var/run/lircd.pid -L /var/log/lircd
Everything seems to be fine except when I use irsend and the -d option to try to send a signal to one of the devices, BOTH of them would light up. When I check the lircd log files, only the intended lircd server picked up the request, so this is very puzzling. It almost looks like that there is a problem in the FTDI driver such that it will broadcast the signal to all USB-UIRT devices present in the system.
Anybody ever saw something like this?
Thanks,
