#17 Driver for HAC4 Plus which uses USB?

[Gregg Casillo]

I recently purchased a HAC4 Plus, and it comes with a USB
connection instead of a serial connection. Is there a way to use my
model of HAC4 with HAC4Linux?

If you have the usb serial converter in you linux kernel you
can.

There are more instructions at:

I've written a kind of mini-howto with a little bit more
details than the above link. It can be accessible at:

http://www.ree.hu/hac4linuxusb

I've only tried this with kernel 2.6 but I am convinced that
the driver can be found for 2.4 as well.

p.s. I think this info should be put on the website and/or
advertised in some cycling forums. I wrote to Rick-Rainer
Ludwig, but got no reply so far.

The USB driver should be automatically mounted as another
tty interface. In my system (Ubuntu) the HAC4+ is on
/dev/ttyUSB0

This can be easily confirmed.

- Connect your HAC4 to your computer via it's USB interface
and get ready to transmit data as normal.
- On a your PC in a terminal type: ls /dev/ttyUSB*
This should list your USB serial devices. There may only be
open, so that should be the HAC4.
-On your PC and in a terminal type the command: cat /dev/ttyUSB0
- On the HAC4 start the data transmission.
- You should then 'see' the data in the terminal as it is
transmitted.

You can then run HAC4Linux and specify the correct tty device.

Hope that helps,
Ash.
