Hello Everyone, I'm trying to usb an FTDI USB chip on Android following the instructions at:
http://www.ftdichip.com/Android.htm http://www.ftdichip.com/Support/Documents/TechnicalNotes/TN_134_FTDI_Android_D2XX_Driver.pdf I can setVIDPID so I'm assuming the FTDI library is installed correctly. But calling createDeviceInfoList causes the sample program to crash. /dev/bus/usb, /dev/usb/* all have permissions of 777 (I know that 666 is all that is needed) Log file snippet follows: D/Depth Reader( 774): Started application.
