When you insert a multifunction PC Card into the PCMCIA slot, only one function is enumerated and initialized, the other functions do not work. When this problem occurs, a code 10 error occurs in Device Manager. This problem occurs in certain scenarios, and it depends on how the function drivers connect to the interrupt request (IRQ). If the drivers use the translated resources (as expected), they connect to an IRQ as "exclusive." This means that the drivers shut out the other function. However, if the drivers explicitly specify "shared," this problem does not occur. Some drivers may incorrectly specify "shared."
This problem occurs because when Mf.sys generates resource lists, it does not handle the allocation of device exclusive resources when more than one child device requests a resource that is marked device exclusive on the parent device. Interrupt resource on a multifunction PC Card is an example of a resource that is marked device exclusive on the parent device that must be shared on more than one child device. When a child device requests a device exclusive resource, it does not receive one, and a code 10 error occurs in Device Manager.
