Android USB Connections Explained:mtp, PTP, and USB Mass StorageOlder Android devices support USB mass storage for transferring files back and forth with a computer. Modern Android devices use the MTP or PTP protocols-you can choose which one prefer.To select a USB connection protocol, open the Settings app, tap Storag

Recently, as a result of the business relationship, we need to install an HP Server that was originally installed with win2003 into a red hat linux6.1. I thought it was a simple task. I ran into the data center with a CD. As a result, I was stunned. No one of the three DVDs was available, and all of them showed medium damage. (Mei's) it's troublesome now. Think that windows can be installed from a USB flash drive, so linux should be fine. The preparat

For the entire USB-storage module, the usb_stor_init () function is its start. However, for the USB flash drive, the function that actually drives the USB flash drive starts with the storage_probe () function. As long as the two parallel lines overlap, it is doomed to start a lifetime of entanglement, no matter whether the middle is a short separation.

The usb_stor_bulk_transfer_sglist () function is confusing. We have mentioned that sglist is used to improve transmission efficiency. As we know, SG aims to transmit a bunch of discontinuous buffers in one DMA Operation. In fact, this is not the case in the story of USB. However, if you don't care about the behavior in the USB core, it doesn't matter. Row 3 and row 3 do not pass data if you exit or break th

Come out and try again later. Basically, each directory in the Linux kernel has a Makefile.

Basically, there is a Makefile under each directory in the Linux kernel. Makefile and Kconfig are like a map of a city. a map leads us to know a city, while Makefile and Kconfig let us know the structure under this dire

Install ubuntu on a USB flash drive and start Linux from the USB flash drive. If we install the Linux system directly on our hard disk, the GRUB of Linux will overwrite the boot guide of window. It is not convenient to carry. So I want to install a ubuntu system on a USB flash drive, which can be started on any computer. Preparations: A 32g

First, verify the USB device is normal : If the laptop is plugged into the USB device itself, there may be a problem with USB can not use the phenomenon. Verification Method:Method One:Plug the USB device into another computer to see if the computer is available. If this device is not available on other computers, th

Install a Linux system to a USB flash drive or a USB flash drive for a linux System Step 1: First insert the usb flash drive to the usb interface of the Computer Host (it is recommended to insert the usb interface to the rear of the hosts box), and then open the UltraISO sof

USB protocol analysis, usb protocol 1. Description structure of USB devices 1. Logical Organizational Structure The logical organization of a USB device consists of four layers: device, configuration, interface, and endpoint. A device usually has one or more configurations. The configuration usually has one or more int

Rome was not built in one day. Before making the USB flash drive work, we actually made a lot of preparations for the driver. We continue to follow our feelings. storage_probe (), 972 to 975 rows, and a series of functions named init _ * are called at the moment. Here some lock mechanisms and wait mechanisms are involved, however, it is only initialization, but it is ignored for the time being. It will be explained later, but remember that each row o

With USB3.0 control chip motherboard, although has become the mainstream of the market, but for most users still use USB2.0, USB2.0 file transfer speed also seems to be unable to meet their requirements. In fact, now USB2.0 speed there is room for improvement, we can use the speed-increasing patch to explore the potential of USB2.0. USB 2.0 Why not reach the 60mb/s? We all know that the theoretical bandwidth of
