Subject: [linux-audio-user] Getting the Echo Mona Laptop to work

Hi all,
I'm trying to get my Echo Mona Laptop card to work, and I've done a lot
of progress thanks to Giuliano Pochini and Ivica Ivo Bukvic, but I'm not
there yet.
The alsa drivers written by Giuliano Pochini, though not currently part
of alsa cvs, are reported to be working for the PCI version of the card.
Echo (the manufacturer) has assured there is no difference in their
windows dirver for the pci card and the pcimcia card, so the linux
drivers should work for the PCMCIA card as well.
The current state:
-My machine recognizes the card properly as (using lspci):
04:00.0 Multimedia controller: Motorola: Unknown device 3410 (rev 01)
When hotplugging the card, the drivers are called correctly, but midway
through loading, there is an error, and the drivers halt. The strange
thing when loading is that the card reports a different serial number
each time the card is loaded. This points to a data corruption problem
somewhere.
This problem looks a lot like a problem discussed in the past on this
list for the Hammerfall PCMCIA card, where people (Ivica in particular)
were having trouble with the Cardbus bridge registers. The problem was
solved by manually changing those registers.
I apparently have the same problem, since the registers for windows are
different for the registers on linux (I checked the registers using
hexdump -v /proc/bus/pci/02/01.0).
The registers are similar but have something like 15 values that differ.
I tried changing the registers manually using setpci, but the problem is
that when changing some values, other values I had already changed
reverted to their old values, and some values could not be changed at all.
So my questions are:
Should the registers for windows and linux be exactly the same or is it
normal to have variations?
How can I force the registers for the cardbus bridge to take on the
values I get on windows?
Thanks very much,
Andrés
PD. Here are the registers for windows:
