I had the same problems with a parallelport dongle. When I removed the
modules "parport_pc" and "lp" the parallel port device was always
powered off and it was not possible to receive interrupts anymore. A
workaround for this "power off" was to append "pnpbios=off"-option to
the kernel commandline.
Maybe this can also help you.
Good hint. Roland, could you try that first. I think this does not
require the parport module loaded, doesn't it?
Attached is a patch registering the PNP device in rtcan_peak_dng.c. This
should also solve the power-down problem.

Is there som additional kernel output visible via "dmesg"?
Yes:

How do you have configured the parport in the kernel? Are there modules
loaded (check /proc/modules)? Retry after removing lp and parport_pc:
Have looked can't see any. Have attached the output of /proc/modules
$ rmmod lp
$ rmmod parport_pc
I get a message that it cannot find these modules in /proc/modules
