Subject: [hsflinux] linux crash
Message-ID: <50729B1D.1060704@hispeed.ch>

Hello

We are testing the HSF driver (free version). But there seems so be a 
problem related to this driver. Sometimes linux crashes (had to power 
cycle the computer). In syslog I can find the following lines:

Are there some known problems?

So, after weeks of painful sessions with vi, I think it kinda works:

OK

We were unable to deduce what type of modem you have.  This means that
it did not respond as a Class 1, Class 2, or Class 2.0 modem should.
If you believe that your modem conforms to the Class 1, Class 2, or
Class 2.0 interface specification, then check that the modem is
operating properly and that you can communicate with the modem from the
host.  If your modem is not one of the above types of modems, then this
software does not support it and you will need to write a driver that
supports it.

What do I do now?
