Kernel/driver/usb/gadget SERIAL.C is a commonly used driver file that can be configured for bulk transmission drive or CD
, but now have USB to serial port device. But new problems have arisen, for example, the minicom under the PC and target computer communication or there are some configuration problems, the following is the Linux USB to the serial port configuration and problems:Note: By default, Ubuntu has a
Device Controller (UDC)-driven implementations supported by the kernel, as well as the implementation of frameworks and different gadget.
Take AT91 ARM9 As an example, the bottom driver is at91_udc.c (for the SOC that supports high Speed USB 2.0 is ATMEL_USBA_UDC.C), it implements the unified interface defined by Gadget.h, and then various gadget on the upper layer Driver (such as SERIAL.C, etc.) call this
problems:Note: By default, Ubuntu has a USB to serial port driver (pl2303) installed.1, # Lsmod | grep usbserialIf there is usbserial, the system supports USB to serial port.2, plug in the USB to the serial port, in the terminal
in the USB to the serial port, in the terminal input command #dmesg | grep ttyUSB0, if a connection success message appears, the Ubuntu system has identified the device.Note: Ubuntu in the virtual machine environment is not automatically recognized by default, you need to click "Prolific Usb-serial
Ubuntu system recognizes the device.
Note:Ubuntu in a virtual machine environment cannot be automatically identified by default. You need to clickClick "prolific USB-serial controller" and select "Connect (disconnect fromHost) "to be recognized by the Ubuntu system.
