USB OTG - FTDI Device problems
Added by Travis Rawson over 3 years ago
Hello,
I am trying to connect a USB-to-RS232 dongle to the USB-OTG port on the MitySOM-5CSE-L2-3Y8 development kit with the reference sd card image running. Using dmesg results in the following:
....
[ 3.638224] usb 1-1: New USB device found, idVendor=0403, idProduct=6001
[ 3.643664] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 3.649476] usb 1-1: Product: TTL232R-3V3
[ 3.652175] usb 1-1: Manufacturer: FTDI
[ 3.654719] usb 1-1: SerialNumber: FTBVYXC5
....
It appears to be recognized, but no serial port is assigned to it. I have had this same cable running on a Ubuntu machine, no problem. Any suggestions?
Thanks!

Hi Travis,
I don't believe the reference project's kernel has built in support for FTDI serial devices. Looking through the kernel I believe you would need to rebuild the kernel with the following support: USB_SERIAL_FTDI_SIO, USB_SERIAL, USB_SERIAL_CONSOLE
