PCMCIA Eject and Insert Problems

NTDEV
1

Hi

Can anybody assist with finding the following issue,unless it is a windows bug…

I have a PCMCIA device connected via an extender card, when emulating the eject and insert via an isolating switch on the extender, Normally I see MPHalt and the start up ok fine. Sometimes when I perform this operation one of a few things happen,

  1. The PC does not power up the card, This happens on quite a few off the shelf cards too, so I can only assume this is a bug with windows XP.

  2. The PC powers up the card but the whole O/S stops,including access vi windbg, i.e destination PC hangs up

  3. The PC hangs up and never powers the card

P.S. This is windows XP, SP2 My NDIS Miniport driver is using 2600 build libs. I could try later versions.

These faults are also seen on other PC’s so its not an isolated fault to the PC

With the debugger attached I always see MPHalt complete before the PC hangs.

Any suggestions!

Thanks

Steve

May be a bad extender. Is this a 16-bit or Cardbus card?

It is a Cardbus card that we are developing, it may even be a fault with the hardware, but they are blaming the driver, but can see how if the driver is downing correctly.

Then it can be PCI related (electrical) problem. maybe even caused by the extender.
A bus probe is your friend…
