    Intel Galileo USB client not detected when booting from SD Card

    muhammadnizami

      I'm trying to upload a sketch persistently, so I tried the "boot from SD card" instructions here: IoT - Step 1: Make a bootable micro SD card | Intel® Software


      I don't have a 3.5mm UART to serial and serial to USB cable, so I'm trying to connect the board to my PC with the USB client on the board.

       

      When the board booted from the board's internal flash, the PC can connect to the USB without problems. But, when the board booted from the SD card, the PC cannot detect the USB device. The PC runs Ubuntu 14.04.

       

      lsusb when the board boots without SD card:
