I have been using a virtual machine for a long time. Recently I want to experience Linux and FreeBSD operating systems on a real machine. Therefore, I decided to install these operating systems on the hard disk, so I had to use a USB flash drive for installation. Record the installation process. 1. Quasi-Work A.

However, simply looking at these two functions, we have to look at the context. In other words, we need to combine the context of the call of usb_stor_bulk_transfer_buf in usb_bulk_transport () to compare the parameters and real parameters, so that we can truly understand and open up this thick fog. Before carefully analyzing usb_stor_B
