- 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
