I followed the CyUSB Suite for Linux document on Ubuntu 14.04, installed Qt4 and libusb 1.0, built the cyusb library. Tried to program the FX3 with cyfxbulksrcsink, write data at end point 0x01 and it worked fine. But when try to read from 0x81, it suppose to return some constant data, but I always read back nothing.
This works on Windows. Do you anything special needs to be done for this to work?
Thanks,
Frank.
