Mudi V2 detects microSD cards as USB drive

Routers Cellular, USB modems

This is not a major issue, but an annoying one. Maybe not even a bug. I guess it is related with the hardware design. Since Mudi has a microSD card reader and a USB connector it would be nice if the system can differentiate them like on Puli to prevent false and accidental operations.

Firmware version is 4.7.2 beta.

Yes, this is related to hardware design.
So, we don't have a very good way to distinguish between them either.

Hm, now I see that Puli also detects memory cards as USB drive sometimes. I am not a professional, but I remember that udev can "mask" devices. Is it possible to mask that hub or device maybe? The hardware ID is static and it is independent as far as i understand.

Openwrt has removed udev for quite some time.
Perhaps you can use the hotplug script to specify the mount path and name to distinguish between USB drives and SD cards in the CLI.
