After configuring an open dmx dongle on FPP8.5 and doing a restart the following error occurs.

2025-04-29 16:57:53.210 (1321) [ChannelOut] /opt/fpp/src/channeloutput/USBDMX.cpp:103: Error 2 opening /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_B001QKLV-if00-port0: No such file or directory

Going into the outputs>other and just clicking on save and then doing a FPPD restart the log is happy.

2025-04-29 17:05:43.353 (2990) [ChannelOut] /opt/fpp/src/channeloutput/serialutil.cpp:184: /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_B001QKLV-if00-port0: Using custom baud rate of 250000

The fppd.log file is attached. It was cleared prior to the reboot to make it easier to find stuff. Each reboot does the same thing and each time a save and FPPD restart is done the dongle comes back to life. There's 2 log files in the zip file. 1 is before and 1 is after a FPPD restart.
