I'm guessing when you set up support for the device you didn't pass
parameters for it. Unfortunately for this device this is necessary since
the driver can't/won't autoprobe for the device. Here's the snippet from
the CDROM-Howto:
4.3.3. Cdu31a Driver
Principal author: Corey Minyard ([EMAIL PROTECTED])
Multi-session support: yes
Multiple drive support: no
Loadable module support: yes
Reading audio frames: yes
Auto-probing: no
Device file: /dev/cdu31a, major 15
Configuration file: cdu31a.h
Kernel config option: Sony CDU31A/CDU33A CDROM support?
README file: cdu31a
This driver accepts a kernel command line of the form:
cdu31a=<io-address>,<interrupt>,PAS
The first number is the I/O base address of the card (e.g. 0x340). The
second is the interrupt number to use (0 means to use polled i/o). The
optional third parameter should be "PAS" if the drive is connected to
a Pro-Audio Spectrum 16 sound card, otherwise left blank.
If the driver is loaded as a module, it uses a slightly different
format. When loading the driver using the modprobe or insmod command,
the parameters take the form:
cdu31a_port=<io-address> cdu31a_irq=<interrupt>
The base io-address is required while the interrupt number is
optional.
The device file can be created using:
# mknod /dev/cdu31a b 15 0
See the file cdu31a for more information on this driver.
Also see the Web page put together by Jeffrey Oxenreider
([EMAIL PROTECTED]) that covers a lot of common problems with these
drives. It can be found at
