When I insert a pl2303 adapter, my system loads three modules:
ch341, pl2303, usbserial.
If I disconnect the adapter my system doesn't unload the modules, and if I reconnect the adapter it doesn't work properly.
To solve the problem I unload the three modules,
with the command "modprobe -r ch341 pl2303 usbserial",
before of reconnect the adapter.
