I am not sure the problem would be the bus number it is basically
just a number allocated in the kernel, it should really matter as
long as it represents the right device. Which as far as we can
see here looks likely.
The chip select being wrong could well be the issue, perhaps the
Windows driver supports multiple chipselects where as the Linux
one doesn't? Do you have access to any datasheets for the SPI on
the AP? Alternatively you could try hacking it to use chip select
0 and see if that makes the system work, seems like a long shot
but perhaps worth a quick go.
Thanks,
Charles
