Hi all. I have problem with WP 7607-2 Seri. When I enable ADB port (“AT!USBCOMP=1,1,10F”) to use with SSH connection via MobaXTerm, after open ADB port successfully I can’t access to UART port. I can’t send AT command to it. When I trying to open UART port, it returned “Invalid argument comport”. But when I disable ADB port, it works correctly, I can send AT command and open UART comport. Help me please, thanks.
My firmware is: Legato Ver: 19.04.0_6fbb8d1e27e320ebcd2971fdae7df87f
Yocto Ver: SWI9X07Y_02.31.01.00 2019-06-14
Seems the ADB port is not supposed to be used.

It’s my logfile when I check usbcomp. My problem is UART port not work when ADB port open. If I set value of usbcomp to “0008010F”, then adb port will open and I can’t send AT command to module WP via UART port. If I set value of usbcomp to “0008010D”, then adb port will closed and disable and I can send AT command to module. ADB port and UART port can’t not working correctly at the same time. I trying upgrade and downgrade to new and old firmware version but problem not fix. 
not sure why I cannot see ADB port with WP7607-1:

Did you level 3 unlock the module? ADB port is not supposed be used by user.

Yes! I have unlocked at level 3. After I open ADB port successfully, I can’t open UART port and send AT command to it. Error message when I trying open UART port is " Can not open COM port: Invalid Argument".
But when I disable ADB port, UART port work correctly
BTW, how can you level 3 unlock the module?
I used AT!UNLOCK=“A710”
I can still enter AT command in the UART console:
root@swi-mdm9x28-wp:~# microcom /dev/ttyAT

Yes! I can do the same as you. But I want to enter AT command in the UART console with AutoPilot , not use microcom -X /dev/ttyAT. Because I have to run automations test case.
I don’t see problem in UART1 as AT command port:
