This is a somewhat frustrating bug, as the hardware drivers for the device work just fine, but the device detection and reset doesn't work. Having looked at it in some depth, I'm not even sure this is a kernel issue: as far as I can tell, the device fails to send any signal over USB when a card is inserted. If the USB cable is disconnected and reconnected, or on first boot, if there is a card in the device, that card is detected, and card changes are detected if one switches a card and attempts to access the old card (the device sends no signal to indicate removal just as it sends no signal on insert, so the kernel believes the card to still be present). It may be that there is some way one can actively poll the device from userspace (this is beyond me), and so run some helper daemon that exits if no supported devices are detected, and otherwise polls or resets the device every N seconds (120 and 300 seem reasonable potential values for N).
