Hey,
I bought a zigbee gateway (home automation thing) that is using CH9102F USB to UART/Serial Converter Chip and I can not find drivers for it on OpenWRT software list.
It looks like there are drivers https://github.com/WCHSoftGroup/ch343ser_linux
I have not tested if this repo but could somebody build it for OpenWRT? I would test it.
Never mind, works now... I could not find exact driver but I tried what would happen if I installed them all
kmod-usb-serial kmod-usb-serial-ark3116 kmod-usb-serial-belkin kmod-usb-serial-ch341 kmod-usb-serial-cp210x kmod-usb-serial-ftdi kmod-usb-serial-mct kmod-usb-serial-mos7720 kmod-usb-serial-oti6858 kmod-usb-serial-pl2303 kmod-usb-acm kmod-usb-serial-simple kmod-usb-serial-ti-usb
and one of them worked... not sure which.
