I'm quite sure the problem is not on the PCMCIA side of things. If the
driver requires power cycling of the device, the problem is in the
driver (or less likely in the hardware). The driver should initialize
the device properly, whether it was power cycled or not. Using PCMCIA
reset would be a workaround. Please talk to serial_cs developers.
