cardbus — CardBus bus driver
The cardbus driver implements the CardBus bus. The cardbus driver supports all cardbus bridges in the system.
The driver supports the following tunable parameters, which may be added to /boot/loader.conf or set via the sysctl(8) command: hw.cardbus.debug Non-zero values cause more verbose information to be printed when a 32-bit CardBus card is inserted or removed. hw.cardbus.cis_debug Non-zero value causes the CIS parsing of the 32-bit CardBus card to be much more verbose and include a complete CIS dump.
