  1. Hello, I have used the digilent JTAG-HS3 programmer simultaneously with other device with FT232H chip and I have probably erased by accident the FT232 chip on Digilent module or there is a problem with drivers - the device is still recognized as Digilent USB serial converter by the system so I think is not damaged, but the cable is not visible in xilinx software. Could you please help me?
  2. Hi I have two of the HS3 both of them show as USB serial converter. What should I do?
  3. I am using an FT232 breakout board to control a rotary sensor through Python 2.7 If I plug in the AD2 first, my python code fails due to "no device found". If I plug in the FT232 first, and establish the connection with Python, everything works OK. How can I track down the cause and resolve it? The errors listed follow: C:\Python27\lib\site-packages\adafruit_gpio-1.0.3-py2.7.egg\Adafruit_GPIO\FT232H.pyc in __init__(self, vid, pid, serial) 148 if serial is None: 149 # Open USB connection for specified VID and PID if no serial is specified. --> 150 self._check(ftdi.usb_open, vid, pid) 151 else: 152 # Open USB connection for VID, PID, serial.
