>Description:
I have a Toshiba Satellite A105-S4324, Windows XP reports a TI PCIxx12 software driver for the functioning Cardbus Bridge.  Toshiba can't or won't specify the exact controller that is built into this laptop. I can't find any TI devices that end in xx12 in the list of supported controllers, and the default CB_UNKNOWN handling just seems to detect the cards insertion, turn on it's power, then turn it off.

I traced through the code a little and found the the device/vendor ids are reported back to the cardbus driver as a -1 return from xxx_read_config call.  I'm currently concluding that this hardware is unsupported by FreeBSD...

If I had to guess, I would say that the power up sequence needs something more to bring the card to life?  If you have any ideas of how to get the hardware documentation from either Toshiba or Texas Instruments, please let me know.
>How-To-Repeat:
sysctl hw.cbb.debug=1
sysctl hw.cardbus.debug=1
sysctl hw.cardbus.cis_debug=1
