38  * This driver attempts to support the Lexar Jumpshot USB CompactFlash
39  * reader.  Like many other USB CompactFlash readers, the Jumpshot contains
40  * a USB-to-ATA chip.
41  *
42  * This driver supports reading and writing.  If you're truly paranoid,
43  * however, you can force the driver into a write-protected state by setting
44  * the WP enable bits in jumpshot_handle_mode_sense.  See the comments
45  * in that routine.
