Hi,

have a problem with HSO drivers. After I suspend/resume my system or plug again modem, I can't connect. I found, that /dev/ttyHS0 is not recreated (although all other ports are created). But. Control port (which is actually /dev/ttyHS0) now becomes /dev/ttyHS1. And if I change hso-connect.sh script to use port /dev/ttyHS1 instead /dev/ttyHS0, then everything work fine. After second modem removal/insert, Control port becomes /dev/ttyHS2. It seems, that Control port is increased every time I re-plug my modem.

Here is a snippet from my kernel logs:

The first I plug it:
[ 40.326513] HSO: Found Network port hso0
[ 40.326657] HSO: Found Control port /dev/ttyHS0
[ 40.326696] HSO: Found Application port /dev/ttyHS1
[ 40.326750] HSO: Found Diagnostic port /dev/ttyHS2
[ 40.326814] HSO: Found Modem port /dev/ttyHS3

The second time:
[ 6.135285] HSO: Found Network port hso0
[ 6.135432] HSO: Found Control port /dev/ttyHS1
[ 6.135473] HSO: Found Application port /dev/ttyHS2
[ 6.137486] HSO: Found Diagnostic port /dev/ttyHS3
[ 6.141295] HSO: Found Modem port /dev/ttyHS4

The third time:
[ 406.971034] HSO: Found Network port hso0
[ 406.971245] HSO: Found Control port /dev/ttyHS2
[ 406.971349] HSO: Found Application port /dev/ttyHS3
[ 406.979405] HSO: Found Diagnostic port /dev/ttyHS4
[ 406.985131] HSO: Found Modem port /dev/ttyHS5

What the problem can it be?

BTW, I'm using Ubuntu 8.04 and kernel 2.6.24.

Also I noticed that after I remove modem, all /dev/ttyHSx ports are closed except /dev/ttyHS0. It seems that module is not able to close /dev/ttyHS0 port (i.e. Control port).
