I want to write a usb application on linux
I don't know the APIs provided by the Linux USB driver, such as the basic API for opening the USB port and reading and writing to the USB.

Open the USB device file directly, read / write read and write, but in most cases you can't read anything, because USB and serial port are different, USB device types are different, and different initial trials are required. Soy oil different operation methods. For example, if you are using a USB mouse, then you can use cat / dev / mouse to get the data sent by the mouse to the PC.

To borrow the landlord's treasure, please ask: how to correspond to the button event on the USB camera in windows.

The driver's open thread detects whether the device has a key (usually using the int endpoint), and if so, records. At the same time, the application must have a worker thread to query the driver at a certain frequency. Submit this message after inquiry. This is a tedious method. You can also notify the application through events.

Open a thread in the driver to check whether the device has a key (usually use int endpoint), if there is a record, and the application must also have a worker thread to query the driver at a certain frequency, and the driver will ask the next application after getting the key message. Submit this message after inquiry, this is a more cumbersome method, you can also notify the application through events
