I'm running Debian sarge on a Sony PCG-505FX laptop, using a
home-built kernel (currently 2.6.11.8 with current bluez patches). I've
had trouble getting SCO working with another dongle, so I thought I'd
try it with the Ambicom card, using the CF <--> PCMCIA adapter that
comes with it.
The card had been working with 2.4 kernels (using the bt950 driver),
but I'd never tried it on a 2.6 kernel before. First thing I discovered
was that I needed the serial_cs module compiled into the kernel, and I
didn't have it (might it not be a good idea to have the hci_uart module
depend on it?). I built a new kernel, and was able to load drivers anyway.
When I plugged the card into the PCMCIA slot, I got this in my syslog:

Attempts to use 'hciattach ttyS3 ericsson' resulted eventually in:

> Connection timed out (110)
... and 'hciconfig -a' tells me the hci0 interface is down. It had
00:00:00:00:00:00 for the MAC address.
From my work with the bt950 driver, I think that the Ericsson
chipset defaults to a baud rate of 57600. So I tried:
hciattach ttyS3 ericsson 57600
and got:
> May 22 16:50:08 cleopatra kernel: h4_recv: Unknown HCI packet type 00

It does appear that the serial ports on the card and the radio
section are not set to the same baud rate. Does this sound likely? Any
suggestions for getting it working?
Thanks,
.....Ron

don't know if this can help you, but when I made the patch mentioned
above (to get my Socket CF bluetooth card working - it worked under 2.4
but not 2.6, like yours) I compared the serial_cs modules in both kernel
versions and found that in 2.6, some code is missing which was present
in 2.4, especially everything regarding high-speed UART chips. Don't know
why all this was removed though...
Because of the missing init code the UART chip didn't get initialized
with the baud rate which hciattach supplied to the serial driver.
Regards
Mathias

It's a 2000E, with an Ericsson chip in it. I found that out a year
ago when I was playing around with the bt950 driver on my Zaurus.
Anyway, thanks for the help, folks, but it still doesn't work.
Doesn't seem to have made any difference as far as I can see. If
nobody's got any more ideas, I'll trace the bt950 driver through and
compare it to the current one. Perhaps that'll give me a handle on
what's happening.
Thanks,
.....Ron

Pavel Machek posted the commands to get the Billionton card working to
the LKML. I verified it and maybe the same will work the Ambicom.
And depending on if it is a 2000C or 2000E it has a CSR or an Ericsson
chip inside. Guess who is who.

Marcel

Hello,
I don't know, if it is exactly your problem, but some bluetooth
PCMCIA (CF) cards have problems with kernel 2.6. Specially
New SOCKET or Billionton card.
There exists patch for kernel 2.6.11, which resolve problems with
these cards. Look at this page for instruction:
http://www.summet.com/x31/socket.html
Find in archive mail with subject "Billionton(?) CF card - success".
