Hi balbes150
Thanks for your great job!
I tried the 4.18.7_20180928 kernel, both debian & ubuntu, there is a bug: the PL2303 usb can not working.
I use lsusb, it shows PL2303 connect. But when I use Dmesg, the end of lines show nothing with ttyUSB0
BTW the PL2303 works very well in Armbian_5.44_S9xxx_Debian_stretch_3.14.29_server_20180729
