[PlanetCCRMA] Re: Echo Mona Laptop driver

[Andres Cabrera]

Thanks again for all the suggestions.
doing:
 cat /proc/asound/devices

  0: [0- 0]: ctl
 25: [0- 1]: digital audio capture
 16: [0- 0]: digital audio playback
 24: [0- 0]: digital audio capture
 33:       : timer

But I don't know what this means....

I tried hotplugging the cardbus card with a terminal with:
tail -f /var/log/messages
and I got the following result:

So again, the problem seems to be that the driver is only compatible 
with the pci version, not the pcmcia version of mona.
I checked the source code to see if the device and Vendor id's match, 
and they seem to be correct: (from Echoaudio.h)

#define DEVICE_ID_56301        0x1801
#define DEVICE_ID_56361        0x3410
#define VENDOR_ID        0x1057
#define SUBVENDOR_ID        0xECC0

lspci reports:
04:00.0 Multimedia controller: Motorola: Unknown device 3410 (rev 01)
        Subsystem: Echo Digital Audio Corporation: Unknown device 0072
        Flags: medium devsel, IRQ 11
        Memory at 20800000 (32-bit, non-prefetchable) [size=1M]

I am already re-compiling the alsa packages for support for this card.

Has the time come to write to Echo to ask for the differences the driver 
should have when using a pcmcia card?

Cheers,
Andrés
