[hsflinux] Current HSF driver doesn't work

Mon Jan 30 16:16:37 EST 2006

Hi,

the current version of the HSF modem driver (7.18.00.07) is known to be 
not compatible with the 2.6.15.x kernel. A patch to solve this problem 
can be installed with the 'hsfconfig --patch' command in a root shell. 
The next release of the HSF modem driver will add official support for 
the 2.6.15.x kernels.

For the other problem mentioned, please make sure that the right country 
is selected with the 'hsfconfig --country' command in a root shell.

If you require more assistance, please send to support at linuxant.com the 
output of 'dumpdiag'. Type the following in a root shell:

---
hsfconfig --dumpdiag
---

Just send us the generated file located in /tmp ('hsfdiag.txt').
It'll help us solve the problem.
