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.

+Cypress M8 CY4601 Family Serial Driver
+
+ This driver was in most part developed by Neil "koyama" Whelchel. It
+ has been improved since that previous form to support dynamic serial
+ line settings and improved line handling. The driver is for the most
+ part stable and has been tested on an smp machine. (dual p2)
+
+ Chipsets supported under CY4601 family:
+
+ CY7C63723, CY7C63742, CY7C63743, CY7C64013
+
+ Devices supported:
+
+ -DeLorme's USB Earthmate (SiRF Star II lp arch)
+ -Cypress HID->COM RS232 adapter
+
+ Note: Cypress Semiconductor claims no affiliation with the
+ hid->com device.
+
+ Most devices using chipsets under the CY4601 family should
+ work with the driver. As long as they stay true to the CY4601
+ usbserial specification.
+
+ Technical notes:
+
+ The Earthmate starts out at 4800 8N1 by default... the driver will
+ upon start init to this setting. usbserial core provides the rest
+ of the termios settings, along with some custom termios so that the
+ output is in proper format and parsable.
+
+ The device can be put into sirf mode by issuing NMEA command:
+ $PSRF100,<protocol>,<baud>,<databits>,<stopbits>,<parity>*CHECKSUM
+ $PSRF100,0,9600,8,1,0*0C
+
+ It should then be sufficient to change the port termios to match this
+ to begin communicating.
+
+ As far as I can tell it supports pretty much every sirf command as
+ documented online available with firmware 2.31, with some unknown
+ message ids.
+
+ The hid->com adapter can run at a maximum baud of 115200bps. Please note
+ that the device has trouble or is incapable of raising line voltage properly.
+ It will be fine with null modem links, as long as you do not try to link two
+ together without hacking the adapter to set the line high.
+
+ The driver is smp safe. Performance with the driver is rather low when using
+ it for transferring files. This is being worked on, but I would be willing to
+ accept patches. An urb queue or packet buffer would likely fit the bill here.
+
+ If you have any questions, problems, patches, feature requests, etc. you can
+ contact me here via email:
+ dignome@gmail.com
+ (your problems/patches can alternately be submitted to usb-devel)
