Re: driver

The i-7565H1 device has a driver installation script from the device 
manufacturer. This script contains the instruction "modprobe usbserial". 
If this is not correct, could you tell me which driver we should use? I 
attach the script to the message. The link to where we got the software:

thanks,

igor
