The first problem with using QT to make a Kindle annotation management software on a MAC is to detect the status of USB devices connected to your Mac. If the development is in Cocoa, there will be a corresponding system API to use, but because I was in the QT platform development, so it is a bit more difficult. Just then, I found a library:libusb LIBUSB IntroductionLibusb designed a series of external APIs called by the application, through whi

The software in Linux is divided into two types: User layer and Kernel layer. For example, the kernel compiles the driver of the temperature sensor, and the lm-sensors is responsible for interpreting the data submitted by the processing kernel at the user level. USB drive is a hardware-driven thing, and Libusb is a library that is provided for application development and USB drive interoperability (reading

also does not require you to write the driver, all the work can be done in the user state. The way to use it is simple, here's an example: Http://sourceforge.net/apps/trac/libusb-win32/wiki/libusbwin32_documentation#IV.Examples, isn't it simple?PrincipleLibusb himself with a kernel driver, named Libusb0.sys, placed in the windowssystem32drivers inside. The user program calls Libusb0.dll, and the DLL puts t

Using LIBUSB can achieve universal USB communication, but the implementation is more complex, you can use HIDAPI to encapsulate a layer, through HIDAPI call Libusb. The specific process is as follows: 1, compile Libusb Download Address: https://sourceforge.net/projects/libusb/files/

the beginning, and this function returns the number of devices. Usb_get_busses function definition: struct Usb_bus *usb_get_busses (void); This function returns the list of buses, which are not available in the higher versions, as explained in the following example 2.2 Operating Device Interface Usb_open function definition: usb_dev_handle *usb_open (struct *usb_device dev); Open the device you want to use, you must call Usb_open to open the device

, run the program, Effect:The last line prints out exactly the Tiny6410 USB device number.Attention: This can only list USB devices that have drivers installed with the Inf-wizard.exe build . At the beginning, I did not pick up the Tiny6410, the program did not output, plug a U disk, or no output, thought is the program or the library has problems, tangled a will, then a flash, plug in the Development Board try it, sure enough, the program run results as shown above.Continue to learn USB, 2 days
