new 2 different adaptors I have checked today and no success 
Status is like above. I have still the last adaptor to come and test...
Please wait until change: https://forum.banana-pi.org/t/bpi-r4-how-to-activate-key-b-pcie2-11280000-solved/17295/43 is not applied in OpenWRT.
it is misleading... pcie2 dedicated for modem 5g is working fine for me - I have 5g modem attached....
You should know this by now.... These slots support both USB and PCIe bus connections, like the docs say. Your modem shows up in lsusb and not in lspci:
So your modem is connected to the USB bus only. Maybe because it doesn't support PCIe, or maybe because PCIe doesn't work in that slot.
OK thx for make it clear. if pcie2 now is fixed (clocks) I will check also how it will be with my modem.

it seems I lost communication to my modem via USB and new device appeared and showing up as MEDIATEK? (https://cateee.net/lkddb/web-lkddb/MTK_T7XX.html ??)

infra_usb_pipe 1 1 0 26000000 0 0 50000 Y >>> in my old configuration on kernel 6.6 it is set to "N" and probably that's why my modem is not discovered now
and of course it doesnt fix BE200 - the card is stillnot found in system so no way to go forward with loading firmware...
The same behaviour I noticed for another Intel card AXE3000H (Chipset AX210)
Only this:
[ 10.122989] Intel(R) Wireless WiFi driver for Linux
and here I dont use any adapter...
