On 2 units same issue, with both 6.40.6 and 6.41.3 RouterOS versions.
The USB modem Huawei E3531 is detected when connected, but no usb ports are available.
This is the output on console:
/system resource usb print detail

I bought 5 pieces of this particular Huawei model because it is reported as “supported” on https://wiki.mikrotik.com/wiki/Manual:Peripherals ![]()
Any advice?
