Billionton Cf Bluetooth Card Is Not Working On The Kernel.img-2.6.22.9-yonggun

[Vitel]

Hi All,

I've faced troubles with Billionton Bluetooth card using the kernel.img-2.6.22.9-yonggun.
As far as I understand, kernel should assign /dev/ttySX device with the card when I plug it into Z. However, kernel doesn't do it according to the dmesg log:

pccard: PCMCIA card inserted into slot 0
pcmcia: registering new device pcmcia0.0
Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing disabled

I suspect that something like this should be added in addition to the log above:

serial 8250 : ttyS0 at I/O 0x3f8 (irq=4) is a 16550A

BTW, serial_cs module is successfully loaded and there are no well known error messges "serial_cs: unknown symbol serial8250".
Does anybody know how fix this issue?

Here are few more logs that I think can be useful:

i don't know if it is the same problem but my belkin cf bt now doesn't work with kernel 2.6.23 from angstrom too
i remember it was working with previous kernel...

Thanks for advice, I'll try this one:

I've tried Angstrom and found that problem was not about kernel, all I needed was

apt-get install pcmciautils

and now both Angstorm's and yonggun's kernels assign /dev/ttyS4 to the Bluetooth card:

pccard: PCMCIA card inserted into slot 0
pcmcia: registering new device pcmcia0.0
Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing disabled
pcmcia: request for exclusive IRQ could not be fulfilled.
pcmcia: the driver needs updating to supported shared IRQ lines.
ttyS0: detected caps 00000700 should be 00000100
0.0: ttyS4 at I/O 0xc48202f8 (irq = 137) is a 16C950/954

However, bluetooth is still not working
Now it fails to

#hciattach /dev/ttyS4 bcsp
BCSP initialization timed out

I'll try this on the Angstrom system, maybe I'm missing something else...

I've finally solved the problem. It's required to do the following command before attaching the /dev/ttyS4:

setserial /dev/ttyS4 baud_base 921600
