I posted a message two days ago regarding a problem with the O2 Micro Carbus
I have uninstalled the old RTP and reinstalled with patch A which I
downloaded today. I ran ‘uname -a’ and confirmed the patch was fully
installed as per the web recommendation.
The machine does not now lock if a 5V card is plugged in but the driver does
seem to do something very wrong with the voltage switching; I say this
because the resettable fuses supplying the sockets in my notebook trip when
the 5V card is activated. I can tell this because the card is not recognised
(pin returns empty sockets), and insertion of ANY other card (3.3V or 5V)
thereafter doesn’t work. The insertion and removal events are recognised by
devp-pccard (with -vv in invocation), but the card details are always blank.
The only way to clear this problem is to turn off the notebook to reset the
fuses. A simple restart won’t work.
If a power-down is not performed and I reboot to Windows 98 or Win 2K they
both fail to see any PC Cards when plugged in (due to loss of power to the
sockets). However, after a power-down and power-up cycle the Windows systems
correctly detect all cards again, and RTP correctly detects 3.3V cards.
However, if you dare to insert a 5V card again when running RTP, bang go the
fuses - another power-down job.
I will reiterate from the previous post that the Cardbus controller is an O2
Micro OZ6832. I notice that the release notes for patch A mention full
support for these now, although I thought the previous version claimed
claimed that anyway.
This strongly points towards a problem with devp-pccard in my view.
Can anyone help with this problem!
