Quickcam BW no go

[Hamish <hamish_nospam@xxxxxxxxx>]

Hi folks,

I am trying to revive an old BW Quickcam. In years past I had it working with an older 2.2 kernel or so. If memory serves that was Debian/potato on a Pentium 75..

These days I am running Debian/etch on a P4 with 2.6.24 kernel from debian's backports.org. I had read there was a fix applied to the qcam kernel module before 2.6.24, I had hoped that upgrading would solve my problem.. nope.

It's a parallel port model, details follow:

$ lsmod | head
Module                  Size  Used by
bw_qcam                11432  0

$ dmesg | tail

but then gqcam locks up when I try to quit.
also gqcam segfaults the first time I try and run it, after that it loads ok.


any ideas on how to awake this old beast?



thanks,
Hamish
