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 Hui

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! Hui

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: [image] 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! Hui

Hi Hui Can you upgrade to the latest firmware : http://source.sierrawireless.com/resources/legato/wpfirmwarerelease/ cheers, Ashish
