With my RaLink RT2760 Wireless 802.11n 1T/2R Cardbus [1814:0701], it
fails right after loading the firmware to the card.
(this is an internal PCI card, not cardbus)

We get those "regbusy errors" and then, the MCU no longer accepts any command.

Oddly though, it can scan and detect the surrounding AP's.
