BCM v.92 Modem Prob -MDK 9.2

Although new to Linux, I'm very experienced with computers.

I installed MDK 9.2, got a dual-boot with WinXP going. The basic install
is nicer than I expected.

Once I got the basic install done I tried getting the modem running, but
have had zero success in the past 2 weeks. I've tried two different methods
to get the proper driver and config for my modem.

My modem is ID'd as a Broadcom (BCM) v.92, using an Intel 82801DB

I found a sample (14.4kbps) driver on the Linuxant website, which is for
Conexant firmware, not Broadcom firmware. But I figured they both burned
their eeproms with Intel's supplied software, so I downloaded and ran the rpm.
Of course I missed one instruction "hsfconfig", which was to be executed
after the rpm. Consequently the modem didn't work.

Before I realized I missed that config command I tried a second method to
get the modem running. A poster on this site, linman, successfully got a
similar BCM modem running on MDK 9.1 back in Aug/Sept. Linman's method
was to download an old RH driver(I think) and rebuild his MDK kernel with
that driver. It seemed like a reasonable approach, so I followed his method.
However, there were two errors in the last step that prevented the driver-
modem link. The errors were a 'mknod' error and a missing config file, I think.

Yesterday someone pointed out that I missed the 'hsfconfig' command while
doing the Linuxant install procedure. Since it is the last command, he
suggested that I run the 'hsfconfig' command to complete that installation.
I have no idea if the second attempt to set up the modem conflicts with the
'hsfconfig' from Linuxant, but I tried it anyway.

The 'hsfconfig' command failed with the following relevent diag output...

+ modprobe -v /dev/ttySHSF
modprobe: Can't locate module /dev/ttySHSF

I looked in my KPPP setup and the file there is /dev/ttySHSF0.
That's why it couldn't find it. I wonder if trying the other install, yesterday, changed it.

Here is more of the 34 page dump IDing my Linux setup...

+ /usr/sbin/hsfconfig --info
Conexant HSF softmodem driver, version 6.03.00lnxt03091800free

If you need license keys, assistance or more information, please go to:

When reporting a problem for the first time, please send
us the file generated by "hsfconfig --dumpdiag".

Then the diag did a lspci -v and returned this for the modem...

Then the diag did a cat -v /proc/pci and returned this for the modem...

Then a cat -v /proc/ioports output this for the modem...

After a bunch more listings of the hsf files loaded by the driver (I presume) it
lists this...

Then at the end this is printed about the modem device...

sda: Unit Not Ready, sense:
Current 00:00: sense key Not Ready
Additional sense indicates Medium not present
[BCMSM] BCM V.92 56K Modem version 3.4.19

Looking for splash picture.... found (800x600, 14470 bytes, v3).
Splash status on console 0 changed to on
VFS: Disk change detected on device 08:00
sda: Unit Not Ready, sense:
Current 00:00: sense key Not Ready
Additional sense indicates Medium not present


The "VFS: Disk change detected..." repeats about 15 or 20 times and the
dump listing ends.

That's the status given by the Linuxant driver install followed by the 'hsfconfig' command. It looks as if ACPI has a conflict.

I wonder if trying to install the old RH driver yesterday interfered with this driver set up.


ONE OTHER INTERESTING phenomenon happened on boot last night. I
opted for Linux on the OS menu and the boot process hung up at an unusual
point. I hit ESC to get the verbose listing and it read something like...

Linux has been booted 24 times without a check, checking...

Then it actually restarted and began to boot again. What's up with that?
Is there some system maintenance I should be doing?

TIA for any help you can muster.

hi al_chemyst

looking at the post you leave at my thread seems like you got correctly installed your /dev/ttySM0 (tell me if i am wrong) if so then mknod is working for you since the arguments structure for the mknod is the same for all of the ttySM* in /dev, any way please take a look at the link i am posting below... Thanks.
