[hsflinux] ALI M5457 AC-Link modem

[Marc Boucher]

Bonjour Marc,

The ALI M5457 AC-Link modem in HP XE4500 notebooks is fully supported.

The problem you have experienced below is most likely due to a timing
issue, which we hope to fix soon.

When this happens, please try unloading the modules with "hsfstop"
and reloading them again ("modprobe hsfserial") immediately afterwards.

The second attempt should (hopefully) succeed.

Marc
