mtp usb device driver

the implementation process of the USB driver model and the sample program in Windows CE, based on the sample code, straighten out the development idea of the driver for the USB device. Similarly, the readers in this article are expected to be the readers and those who are r

H. If you are interested, read the source code. USB devices are actually complicated, but the Linux Kernel provides a subsystem called USB core to handle mos

devices in the Linux kernelFor the connection on the specific bus external devices have a struct device corresponding, such as platform equipment has platform_device corresponding to it, which platform_device structure is as follows: struct Platform_device { const char * name; Device name to match the name of the driver and, if successful, into the driven probe f

Linux USBDevice Driver Framework Analysis In fact, all the device drivers in Linux follow the same Convention-representing the structure of the driver program (which is more appropriate with the driver, it should be called a better driver, the struct should contain all the r

The USB host will enumerate the devices after it detects that the USB device is plugged in. Why enumerate? Enumeration is to read the various descriptor information from the device, so that the host can load the appropriate driver according to this information, so as to know

, the Windows version is too low For some friends who are still using Windows 95 or Windows 97 systems, even if the computer is equipped with a USB interface, because the operating system before Windows 98 does not support USB peripherals, install the driver anyway, Setting the CMOS parameters does not allow the removable hard drive to work properly. One workar

I do not know the USB audio device class before developing the driver for the USB audio device. I thought it was a hid driver and it should be easy to develop, later, I found myself in an unknown field. Thanks to the previous deve
