《嵌入式系统设计与实例开发实验教材二源码》Linux内核移植与编译实验

INTRODUCTION

  The USB serial driver currently supports a number of different USB to
  serial converter products, as well as some devices that use a serial
  interface from userspace to talk to the device.

  See the individual product section below for specific information about
  the different devices.


CONFIGURATION

  Currently the driver can handle up to 256 different serial interfaces at
  one time. 

  If you are not using devfs:
    The major number that the driver uses is 188 so to use the driver,
    create the following nodes:
	mknod /dev/ttyUSB0 c 188 0
	mknod /dev/ttyUSB1 c 188 1
	mknod /dev/ttyUSB2 c 188 2
	mknod /dev/ttyUSB3 c 188 3
		.
		.
		.
	mknod /dev/ttyUSB254 c 188 254
	mknod /dev/ttyUSB255 c 188 255

  If you are using devfs:
    The devices supported by this driver will show up as
    /dev/usb/tts/{0,1,...}

  When the device is connected and recognized by the driver, the driver
  will print to the system log, which node(s) the device has been bound
  to.
  

SPECIFIC DEVICES SUPPORTED


ConnectTech WhiteHEAT 4 port converter

  ConnectTech has been very forthcoming with information about their
  device, including providing a unit to test with. This driver will end up
  being fully supported.

  Current status:
    The device's firmware is downloaded on connection, the new firmware 
    runs properly and all four ports are successfully recognized and connected.
    Data can be sent and received through the device on all ports.
    Hardware flow control needs to be implemented.

  For any questions or problems with this driver, please contact Greg
  Kroah-Hartman at [e-mail]
