[cpia] Strange problem with CPiA drivers

[madcat@ghostfield.com]

Hi,

I've been having some -weird- problems lately. I used to use RedHat 6.0,
with the CPiA drivers. I think version 0.4.3, they weren't in the kernel
yet that shipped with RH 6. That all used to work just fine, everything
built as modules (parport/parport_pc/parport_probe/videodev). 

Then I switched to SuSE 6.4. Built everything as modules again.

The parport_pc module loads and reports my parallel port right
where it should be; ECP capable, using IRQ 7 and dma channel 3. 

If I load the lp module, it loads up just fine and initialises.

If I load the parport_probe module it reports a VLSI PPC2 camera
as being attached to parport0. The output from the /proc/parport/0/autoprobe
file is as follows:

CLASS:MEDIA;
MODEL:PPC2 Camera;
MANUFACTURER:VLSI Vision Ltd;
DESCRIPTION:Parallel Port Camera;
COMMAND SET:CPIA_1-20;

If I load the cpia module (whether with insmod or modprobe)
the following message appears in syslog (rest of the module loads
included):

Linux video capture interface: v1.00
parport0: PC-style at 0x378 (0x778), dma 3 [SPP,ECP,ECPPS2]
parport0: detected irq 7; use procfs to enable interrupt-driven operation.
parport0: PC-style at 0x378 (0x778), irq 7, dma 3 [SPP,ECP,ECPPS2]
parport0: read2 timeout.
parport_probe: succeeded
parport0: Multimedia device, VLSI Vision Ltd PPC2 Camera
V4L-Driver for Vision CPiA based cameras v0.5.0
Parallel port driver for Vision CPiA based cameras v0.5.0
cpia_pp.c:cpia_pp_register(1307):failed to cpia_register_camera
  0 camera(s) found

My entire setup hasn't changed one bit from what I used with RH 6,
and I really would like to get my webcam working again :)

Does anyone have any ideas or clues as to what might be
the problem?

Thanks,
Ben
