[PARPORT] Initialisation of Freecom Traveller CD

Dear members of the Linux-Parport list,

I've a little problem to use my Freecom Traveller CD (IQ cable
interface) under Linux with
a laptop computer (toshiba cs210. Redhat 5.1, Kernel updated to 2.2.1).

I can't (re) initialize correctly the CD player, and it is not
recognized by the "pcd" driver.

I read in the PARPORT home page the following

which seems to correspond to my problem. However the insmod/rmmod trick
doesn't solve it!
When trying to load the pcd module by "insmod pcd" I receive a message
stating that the device is busy or off.

The only way I found to solve this problem, is first to boot under dos,
which loads then
the freecom cd-driver (.sys device) and initializes it correctly. After
that I can re-boot to linux.
This solution isn't very handy, as I'd like to use the advanced power
management feature to
suspend the computer, and switch it back without having to repeat the
whole boot process.

Any idea, how to reset correctly the interface, without using the dos
driver ?
