CDC-ACM无需为产品开发专用的USB驱动程序,但无法达到HID类设备的在所有系统上面的免驱效果。目前已有不少系统已集成CDC-ACM驱动,但不支持串口全功能应用 CDC-VCP串口主要是指使用厂商专用USB转串口驱动和通信协议实现的串口,需要配合产商开发的专用USB转串口驱动才能使用 STM32 USB-CDC软件框架 (23条消息) USB CDC...
最典型的应用的就是4G模块。 GD原生并不支持双USB CDC-ACM,不过他们给了一个复合设备的demo,是hid+打印机的,可以在GD32F4xx\\_Firmware\\_Library\Examples\USB\USB\\_Device\composite\\_dev\\_hid\\_printer找到它。然后网上有人基于STM32F7设计过多个USB CDC-ACM复合设备(https://shequ.stmicroelectronic...
这里笔者使用的是device模式,和上位机的USB通信模式可以用cdc-acm也可以用hid。作为 cdc-acm的时候,...
USB-HID是Human Interface Device的缩写,属于人机交互操作的设备,如USB鼠标,USB键盘,USB游戏操纵杆,USB触摸板,USB轨迹球、电话拨号设备、VCR遥控等等设备。 TPYBoard借助micropython除了具有usbhost功能以外,还可作为USB-HID设备来应用,这里重点讲述如果作为鼠标和键盘使用。 一、作为鼠标应用(1)编辑 boot.py ...

Here is what I see in /sys/bus/usb/drivers/: btusb cdc_acm hub usb usbfs usbhid uvcvideo My file path was a bit different /sys/bus/usb/devices/2-3:1.0/driver/2-3:1.0/tty/ttyACM0/device/driver/module/drivers# but this is what I got: usb:cdc_acm Thanks again....
