For the last few days, I'm trying to access two SIM7600E-H installed in the miniPCIe slots of the RBM33G card. The problem is that the router creates only one serial port for two modems, when there are 2 modules in the list of resources.
This problem was tested by me on two releases of the system:
[*] The jumper (Load for USB to miniPCIe) from the board was removed.
[*] I previously tried to enter the command "/system routerboard usb set type=mini-PCIe".

5 days without reply from the developers, my message was duplicated to the mail: firstname.lastname@example.org, but there is still no answer.
I found a similar problem on the forum, created back in April 2018:
viewtopic.php?f=3&t=133222&p=663477&hil ... 3g#p663477
This problem is of a massive nature and its solution should be immediate, but apparently the developers have a different opinion on this matter.
Yesterday, I received a request from technical support to send "Supout.rif". Sent in the reciprocal message on the ticket [Ticket # 2018070222003817], also I post it here.
13 days have passed, all that has happened during this time, so this employee of those. support has combined two of my requests:
a few minutes later..Your email with ticket number "2018070222003817" is merged to "2018062822003851".
This device has limited available USB endpoints.
In initialization process SIM7600E-H take up more than half of available points, that's why only one card can work correctly in Your setup.
Please contact SIM-COMM and discuss possibility of modified firmware that takes up less USB endpoints.
There is a feeling that no one is interested in solving this problem. Since if those support had carefully examined my request, they would have seen that these are two physical sim7600 modules with one port and one channel on one port. What are the end points in question (and their limitations) - it is not clear. Each individual device hangs at its 1-1 address and 1-2 on the bus of the built-in USB-hub 1-0.
