I have had an MC7455 module for a couple of weeks with no luck at all getting it even recognized on Multiple Ubuntu/Debian machines. I plug the module in a mini-pci port but it doesn’t even show up at all on the machines I tested it up with with Intel/AMD platforms. If I swap out MC7455 with a mini-pci wifi module I see it with no issues. In both cases I check with lspci. With the Wifi module I can see the pci bus address and the device name as expected. When I plug the MC7455 in the same exact port I don’t see anything. Again, I have seen the same behavior across multiple machines. And they all acted as if the MC7455 doesn’t exist. One of the machines becomes really slow if MC7455 is plugged in but I still don’t see it appear in the system.
Do I happen to have a bad chip or I’m I missing something ?
I appreciate any help and thank you in advance.
