Hello --

I recently acquired the Zoom model 4312 bluetooth PCMCIA adapter for my
eMachines M5312 laptop running Fedora Core 2 (I want to use it for my
bluetooth mouse).  The whole set-up works fine under Windows-XP, so
apparently there is no hardware incompatibility, but it hangs the
machine under Linux.

Prior to the malfunction, everything seems to be OK with the exception
of an error message when the PCMCIA card is initialized: "cs: warning:
no high memory space available!" and "cs: unable to map card memory!"
(full dmesg trace and much other system info included as an
attachment).  The card seems to initialize and flashes its L.E.D.  I
did no system configuration for the card beyond installing all of the
bluez packages from the FC2 repositories.  I don't know how to resolve
the memory-map problem or if it is relevant.

The problem is that when I do "hciattach ttyS16 bcsp" (per
http://sourceforge.net/mailarchive/message.php?msg_id=9958619), it
stays up long enough to display the next shell prompt, and then the
machine completely hangs.  The caps-lock L.E.D. starts _flashing_ (and
continues to do so indefinitely -- strange, I don't know what that
means) and the video display remains unchanged, but the machine is
completely unresponsive to all input: the keyboard, the touch-pad and
mouse-buttons, the connected ethernet interface... completely hung.
Network-connected ssh's go dead, the machine will give no visible
response to any keystrokes at all, the mouse-pointer will not move,
etc.  The only way to get it restarted is to hold down the power button
long enough that it turns off uncleanly.

I'm no expert on PCMCIA nor Bluetooth, so I am clueless as to how to
address this.  I don't know if this is the BT protocol driver or the
PCMCIA config that is causing the problem, but it is hard to deal with
due to the machine being so totally disabled.  I've retried many times
and it is repeatable very consistently.  Should I try a PCMCIA mailing
list?  Am I correct to do the hciattach command?  If I don't, the card
seems not to be noticed by hciconfig (see attached logs).

Any help or advice is greatly appreciated -- thanks very much in advance.
