I had rmmod usbserial but the file was there.so i
deleted it and re-create it.
No this file corresponds to the lcd.i just unplugged
it and the file wasn't used.
Just a little note.Is there any solution via udev?
It finds the lcd as a usb device.My main purpose is to
have a directory /dev/lcd/ which will create and
delete the devices dynamically.that's why i'm using
udev.
ok forget it for now.can i do something else?nobody
ever had this problem in the past?
thx michael.
