MC7455 v6.48.4 - invalid port

Mon Oct 04, 2021 7:36 pm


I have an RB912UAG-5HPnD with an Sierra MC7455 with all USB3 pins taped out, it is working fine in MBIM and PPP in v7.1rc1-4.

I am trying to investigate an issue with v7.1 and the modem getting stuck by checking if this issue happens in v6, I downgraded to v6.48.4 (also tried long term 6.47 and dev 6.49rc) but in all v6 versions I have a problem where the usb1 port is shown as invalid and having 4 channels:

I have some devices in the field using RBM33G and MC7455 running 6.44.2 where it shows 2 channels and they are working just fine.
I also tried playing with the "Ignore DirectIP Modem" setting but it didn't help either.

I also checked the AT!USBCOMP in both rotuers and it is the same 1,1,50D:
