    FX3 BulkSourceSink can't be read Ubuntu 18.04



      My problem is same as: cyfxbulksrcsink bulk read from 0x81 not working on linux .

      I use FX3_SDK_1.3.4 on Ubuntu 18.04, use cyusb_linux_1.0.5 to flash USBBulkSourceSink example from https://www.cypress.com/file/140061/download into FX3 board (tested with both pre-built image, and clean/build by ezUsbSuite). After firmware is flashed, I can send data to FX3, but it returns 0 bytes when I read from Bulk OUT.

      The USBBulkAuto example (https://www.cypress.com/documentation/code-examples/ez-usb-fx3-usb-bulkloop-auto-example ) works, I can write & read using cyusb_linux application.

      I'm using SuperSpeed Explorer Kit FX3 board.
