Usb cdc acm driver example serial#
With the gadget serial driver and the host side ACM or generic serial driver running, you should be able to communicate between the host and the gadget side systems as if they were connected by a serial cable. Host side driverは、ACM compliant driverあるいはsimple bulk in/out interfaceと通信できるドライバである可能性があります。Gadget serial は、Linux ACM driver、Windows usbser.sys ACM driverあるいは、Linux USB generic serial driverによってテストされます、 Gadget serial has been tested with the Linux ACM driver, the Windows usbser.sys ACM driver, and the Linux USB generic serial driver. The host side driver can potentially be any ACM compliant driver or any driver that can talk to a device with a simple bulk in/out interface. Host-side systemから見ると、gadget serial device は、CDC ACM compliant class deviceあるいは、bulk in で bulk outするendpointを有する、単純なvender specific deviceに見え、他のserial deviceと同じように使われます。 On the host-side system, the gadget serial device looks like a CDC ACM compliant class device or a simple vendor specific device with bulk in and bulk out endpoints, and it is treated similarly to other serial devices. On the device-side Linux system, the gadget serial driver looks like a serial device.ĭevice-side linux systemから見ると、gadget serial driverは、seirla deviceのように見えます。 Gadget serial driverは、USBを介して、hos PC上で動作するCDC ACM driverあるいはgeneric USB serial driverのいずれと通信をします。 The gadget serial driver talks over USB to either a CDC ACM driver or a generic USB serial driver running on a host PC:

It runs on a Linux system that has USB device side hardware for example, a PDA, an embedded Linux system, or a PC with a USB development card. The gadget serial driver is a Linux USB gadget driver, a USB device side driver.
Your Linux based system should mount sysfs in /sys, and use “mdev” (in Busybox) or “udev” to make the /dev nodes matching the sysfs /sys/class/tty files.ĭriverのバージョン2.3では、major / minor device nodeが静的に定まっていませんでした。Linux based systemにおいてsysfsを/sysでmountし、(BusyBoxであれば)mbev, そうでなければ"udev"によって、sysfs /sys/class/tty filesを/dev nodeを一致させてください。 Overview With version 2.3 of the driver, major and minor device nodes are no longer statically defined.
