Hi,
We manufacturer a PCI card as part of our product. Recently we have had a
number returned by customers as faulty.
On investigation I find that what actually happens is that the faulty
cards are not detected by Windows. ie ‘devcon hwids *’ does not list the
card. Just as if the card where not plugged into the PCI slot. Doing a
‘devcon rescan’ does not change the situation.
But I have also found that if I put one of the ‘faulty’ cards in a
different PCI slot then it is detected and goes on to work correctly -
indicating that the card is not undetectable.
My questions are:
1: Are there any circumstances when the system (pnp manager, BIOS or
whatever) will ignore a device.
2: Is there a way to force the system to rescan for devices - at a lower
level than ‘devcon rescan’ which does not help.
