Hello

I have LtAP (big one) with LTE Card and Lora Card. All work fine

I like to use USB port for USB Flash memory to have extra space. Is it possibe ? To use USB flash when use 2 mPCI-e cards on device

No, it is not possible to use the top miniPCIe slot and the USB type A port at the same time.

See https://help.mikrotik.com/docs/display/UM/LtAP

MiniPCIe 1 (top slot) supports PCIe and USB 2.0 cards but is shared with the USB 2.0 type A port (can use either the USB port or miniPCIe slot at the same time). It can be used only for SIM slot #1.

In meanwile I try... LtAP doesn't see USB. To bad....It have small amount of memory for event store....
RB33G have USB and micro SD, M.2 card but no Wifi and GPS.

Thank for reply
