Weird, I cant think of something now.
I can try something in the morning
okay 
Do you want me to use your build for clarity - just in case?
No point if its from the same source
Oh its me. I didn't update image build source - my bad. trying now.
@robimarko: does flags need to also have RBSPI_HAS_USB to support USB mini-PCIe devices? My guess is that GPIO 15 toggles power for the slot, and the slot is either PCIe or USB depending on which interface the card uses.
Hm, haven't thought about USB to PCI devices as the SoC has a native PCI-E slot.
It could be added since it only registers USB port,but I dont think that maintainers will really like it
I meant that mini PCIe has pins for an actual USB device on it that can be wired directly to the SoC's USB interface. A lot of LTE cards are actually implemented that way and not as PCIe devices.
That's actually a good point. The R11e-LTE which comes as part of the wAP R kit has USB interface, same as EC25-E etc.
It's easy to try; just add the flag to robimarko's changes.
I'm building already!
Its allot better -

@dehrmann Awesome hint.
Will then add this to my branch too to be included in PR.
@borsss Can you note which LED matches what on the device?
Its the 3rd signal bar (led3) but I am not sure if this is the most relevant one to use.
LEDs 1,2 and 3 marked blue.
Ok, so LED1 is supposed to be power LED.
LED2 is WiFi.
And they are using the third LED in a combination of first two as signal strength bar.
Cool trick but I don't think that we have triggers for that.
User LED should then be the one next to ethernet?
Have I got it right?
User LED is next to the WiFi sign. I cant seem to be able to figure our what control led does tho.

Whats LED1 if left to the wifi is user?
I dont know whats control LED from GPL too.
LED1 is on my picture above - in blue. It is first in the series of LEDs allocated to indicate mobile signal strength. Or this is what I think at this time of the day at least!
Ok.
But then I really dont get whats user LED.
User LED is WiFi indicator - /sys/class/leds/rb:green:user
OK,got it now.
Only mistery is control LED.
