MangOH: USB-serial device doesn't create /dev/ttyUSB1

Hi-

On mangOH Rev8 with WP8548 mounted, I plugged in USB-serial device into USB host receptacle and got this from dmesg:
[ 2164.701693] usb 1-1.3.2: new full-speed USB device number 8 using msm_hsic_host
[ 2164.759560] ftdi_sio 1-1.3.2:1.0: FTDI USB Serial Device converter detected
[ 2164.772378] usb 1-1.3.2: Detected FT232RL

[ 2164.789714] usb 1-1.3.2: Setting MaxPacketSize 64
[ 2164.802441] usb 1-1.3.2: FTDI USB Serial Device converter now attached to ttyUSB1
and follow by lsusb:
Bus 001 Device 008: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC

However, I don’t have /dev/ttyUSB1 shown up. Instead, I just have /sys/class/tty/ttyUSB1 shown up.

Question is, how to create that device nod as /dev/ttyUSB1?

thanks!

Hi awneil,

What I am asking is /dev/ttyUSB1. The /dev/ttyUSB0 is actually the USB interface between mangOH and host PC.

In addition, I have mentioned that I am using Revision 8 board that is supposed to have the problem fixed in your link.

thanks

Hi Hui,
What is the firmware revision on your board and legato version ?
CM info
Legato version

Hi asyal

It is the latest. I followed the instruction of FAE to update the firmware in module a few weeks ago.

thanks!

Hi Hui,
Can you redowload to make sure everything is done properly?
I am wondering if something went wrong with your original process.

Hi sayal,

Here is what I have now:

And I followed the guide from
http://source.sierrawireless.com/resources/legato/wpfirmwarerelease10/

Please let me know if the process I used is correct.

thanks!
