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/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.
Current status:
The USA-18X, USA-28X, USA-19, USA-19W and USA-49W are supported and
- have been pretty throughly tested at various baud rates with 8-N-1
+ have been pretty thoroughly tested at various baud rates with 8-N-1
character settings. Other character lengths and parity setups are
presently untested.

Most devices using chipsets under the CY4601 family should

If you have any questions, problems, patches, feature requests, etc. you can
