Hello,  
I have a little problem with the CardBus Bridge that
we bought recently.  When Linux bootup, the OS see all
the devices after the CardBus twice.  For example, we
have only 1 device called "VIS16" after the CardBus
but the the "lspci" display twice. Does anyone have
any idea why?  Also, dmesg showed some conflict in the
bus segment which has the "VIS16" device.  Please let
me know if you need more information.

Thanks in advance,
Todd Nguyen
