Dear developers,

Hello. I have a Broadcom 43227, with ID 14e4:4358. According to
previous threads, I patched and recompiled the module 'bcma' by adding
PCI_DEVICE(PCI_VENDOR_ID_BROADCOM, 0x4358) to host_pci.c. However, it
does not work as well.

I am using 3.4.9-1-ARCH kernel, and I got the following dmesg after
inserting the module b43. No new interfaces showed up.

[  386.153119] bcma: Found chip with id 0xA8DB, rev 0x00 and package 0x08
[  386.153164] bcma: Core 0 found: ChipCommon (manuf 0x4BF, id 0x800,

[  386.253686] bcma: No SPROM available
[  386.293112] bcma: Bus registered
[  428.245922] Broadcom 43xx driver loaded [ Features: PMNLS ]

I have no ideas about what is going wrong, whether the SPROM or the
b43 driver. I would like to test new patches and give feedback as far
as possible.

Thank you and best regards.
