UM7 - Unable to set CREG_COM_SETTINGS

edit

Hello,

I am trying to setup Um7 imu with my husky. It is a FTDI USB Serial Device converter.

output of dmesg | grep tty

[ 3.555666] usb 1-8: FTDI USB Serial Device converter now attached to ttyUSB1

Output of rosrun um7 um7_driver _port:=/dev/ttyUSB1

[ INFO] [1537164278.276594468]: um7_driver successfully connected to serial port /dev/ttyUSB1.

[ERROR] [1537164225.635399388]: Unable to set CREG_COM_SETTINGS.

FTDI udev rules (tried these two; presently using the 2nd):

#SUBSYSTEMS=="usb", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", MODE="0666", SYMLINK+="ftdi_%s{serial}"

SUBSYSTEMS=="tty", KERNEL=="ttyUSB[0-9]*", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", MODE="0666"

I looked into this post but it is a different robot and did not have any definite answer. Also looked into this um7 github issue and made sure my user is a member of the dialout and also my dialout is listed for ttyUSB1.

Any pointers will be appreciated.
