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/libusb-1.0/ When compiling, to add--disable-udev parameters, we do not use this Lib For this machine use: ./configure--prefix=/opt/libusb1.0--disable-udev make make install If you cross-compile to arm Develop

Recently I am reading the spec of USB hid: Http://www.usb.org/developers/devclass_docs/HID1_11.pdf As you can see, when item isLocalWhen btag = 0000 correspondsUsage. The meaning of this usage was not understood at first. I thought it was wrong. It should be written as a usage ID, and someone on the Internet also said that this usage is actually a usage ID. After some research, I finally understood that the above understanding is wrong. This u
