libusb test demo

libusb-test

1.compile command

chmod +x build.sh
./build.sh 
or
gcc -o libusb libusb-test.c -lusb-1.0 -lpthread -lm

2.功能

• 支持bulk/interrupt endpoint 数据读写
• 支持hotplug
• 支持命令行参数
• 支持快捷发送数据
• 支持将收到的数据保存为文件
• 支持'lsusb'功能，可列出系统所有usb设备
• 支持打印显示特定usb设备（VID:PID）的描述符

3.使用实例

1. help

./libusb -h

2. list usb devices

sudo ./libusb -l

bus: 001 device: 001, VID: 1d6b PID: 0002, EHCI Host Controller bus: 002 device: 064, VID: 0471 PID: 0999 bus: 002 device: 003, VID: 0e0f PID: 0002 bus: 002 device: 002, VID: 0e0f PID: 0003, VMware Virtual USB Mouse bus: 002 device: 001, VID: 1d6b PID: 0001, UHCI Host Controller

3. print descriptor

sudo ./libusb -v 0471 -p 0999 -a

this wil print: device descriptor，configuration descriptor, interface descriptor, endpoint descriptor.

4. bulk transfer

sudo ./libusb -b
or
sudo ./libusb

5. interrupt transfer

sudo ./libusb -i

6. save as file

sudo ./libusb -f
or 
sudo ./libusb -ffilepath

7. send data quickly

enter 'test64' when the program is running. also enter test128, test200, etc.
