2009-02-02 12:43:31 Gavino description 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. uname -a Linux veriton 2.6.24-23-generic #1 SMP Mon Jan 26 00:13:11 UTC 2009 i686 GNU/Linux Thanks.
