Installation instructions for installing the Sonnet Pro Dual CompactFlash Adapter ExpressCard/34 Dual-slot CF Memory Card Reader & Writer Adapter into a supported Mac or Windows computer.
One should insert CF cards into the slots only when the adapter card is ejected because the interface to CF cards is ATA and ATA can only instantiate itself to the system when the adapter card is inserted. You can unmount and then remove CF cards when the adapter is inserted, but you can't plug in new ones unless you first power off and eject the adapter card.
Your computer may not be fully supported by the Qio BIOS. If you boot with SxS cards inserted into the Qio, it forces allocation of the busses and memory space needed. Some computers will refuse to allocated bus space for later insertion unless two SxS cards are inserted before booting.
If you are having hot plug issues, not basic SxS functionality, you can use CFScan utility to force the Qio to "see" a newly inserted device.
