Last time, I was initially exposed to the mounting problem of Android USB client, so I wrote the first article about the feelings. There are still some problems in many places, some of which are not clear enough, so I want to continue writing. First, the last verification shows that the device can be mounted, but only one storage device can be mounted at a time. Secondly, what I said last time about the driver of the device node, there is also a problem, in fact itself there is a tegra-udc.c cre

To facilitate understanding of the following description, Let's first look at the vold (managing periphera

It includes the transmission of event messages from the kernel layer to the user layer, and the introduction of vold. This article will continue to introduce the mounting of the SD card, but this article does not involve detailed analysis of the Code, because this part of the online information, I will post it at the end of the
