Hello Clemens and Ewald,
Bought this card the other week, been looking into making it work on my
linux box. I am not a coder, so what follows is speculative.
I have both the UA-25EX and the UA-55, so made some lsusb -v comparisons
and deductions:
(In the next mail (because of mailing list limit
Hello Clemens,
concerning the UA-55, in addition to the quirk from you I tested the
following quirk
{
USB_DEVICE_VENDOR_SPEC(0x0582, 0x012f),
.driver_info = (unsigned long) & (const struct snd_usb_audio_quirk) {
.vendor_name = "ROLAND",
.product_name = "UA-55",
Hello Clemens,
I added the output of the selfmade kernel with the quirks you suggested,
dmesg gives

[ 7360.550016] usb 1-3: New USB device found, idVendor=0582, idProduct=012f

Are there any error messages in the system log (/var/log/messages or
the output of dmesg) after you've loaded the driver?

Hello Clemens,
aplay and arecord only show the internal card, not the ua-55 but amidi shows
Dir DeviceName
IO hw:1,0,0 UA-55 MIDI 1
which looks good.
aplay sent back the following
aplay -D default:UA55 *

Hello Clemens,
I tried the new quirk, but no success. The lsusb -v gives the same
output as before.
When I use alsamixer, I have no controls. At least the card is mentioned
in /proc/asound.
Which steps should be next to bring the card to life?
Best regards,
Ewald

Hello,
the Roland UA-55 is not recognized by Alsa. Is there a way to use this card?
