How to FIX this bug ttyUSB ? Thanks for your help.

Its not a bug, it's the driver not knowing the device ID (yet).

If your kernel version is better than 2.6.26 you should be able to say:

Code: Select all

echo "12d1 1506" > /sys/bus/usb-serial/drivers/option1/new_id

This is the way to tell the driver a new device ID on the fly.
