A SDXC card is connected to a USB OTG port through a SD-USB adapter.
This SD-USB adapter corresponds to USB3.0.
It is recognized as 0 GB and the contents of SDXC cannot be seen.
If it is unmounted and then mounted, it is mounted correctly and the contents can be seen.
If the SD-USB adapter of USB2.0 correspondence is used, this problem will not occur.
Is this a problem of a SD-USB adapter?
