USB serial communication with Roboteq sdc 2130 - Raspberry Pi Forums

hello all,
doing project want use raspberry pi communicate motor controller using usb connection. motor controller has functionality, having trouble getting work. posting here , on manufacturers website in hopes find issue. below code trying send via usb motor controller. asking motor controllers device id , expecting reply after send it. if there errors in code or how going this, appreciate can provide.

code: select all

import serial import time  ser = serial.serial('/dev/ttyacm0', 115200, bytesize = serial.eightbits, parity = serial.parity_none, stopbits=serial.stopbits_one, wiritetimeout = 0, rtscts = false, dsrdtr=false,xonxoff=false, timeout = 10)  time.sleep(2) command = '?fid' ser.write(bytes(command.encode('ascii'))) s= ser.readline print str(s) 

/dev/ttyacm0 uart on gpio pins (pre-pi3). device else. plug in running pi , type dmesg in terminal see if pi can identify , assign device driver it; should see /dev/ttyusb0 (or @ least device added).
