Dear Warner,
Thanks for your support. my probe is getting called for all
the bridges not for my pci device. so please provide the fix .
OR=20
Is any other way available for making my driver to override the probe of
cbb driver for my corresponding device (With out changing cbb driver).
With regards,
Bagavathy kumar .M

That's not why your probe isn't called. Setting a description is
standard behavior for the probe routine. Are you sure that the device
probe routine is getting called at all for any device? Have you tried
just leaving cbb out of the kernel? I recently fixed the original
problem in cbb (the fact it doesn't check the bridge type too), maybe
you could try to pick up that fix as well?
