the back story
It seems that everyone of the USB serial devices I purchase nowadays
is based on WinChipHead CH340 chipset. The sad thing is the last
two orders I've placed for usb serial dongle have indicated they were
Prolific pl2303 based, but when they show up they are CH340 based.
Sadly none of them appear to work, whereas all the pl2303 ones just
work.
