Recommended firmware is very difficult to connected via USB

[ByronDong]

Hi, everyone

Smoothine board，there is a connection problem

according to this link

The same hardware environment using mark recommended firmware is very difficult to connected via USB. SD-card is always accessible through Windows explorer.

With the "official" firmware there are no connection problems.

Hi Byron,

are you saying that the official firmware does not show the SD drive in the Windows Explorer?
