+ * jumpshot driver v0.1:
+ *
+ * First release

+ * Current development and maintenance by:

+ *
+ * Many thanks to Robert Baruch for the SanDisk SmartMedia reader driver
+ * which I used as a template for this driver.
+ *
+ * Some bugfixes and scatter-gather code by Gregory P. Smith
+ * (greg-usb@electricrain.com)
+ *
+ * Fix for media change by Joerg Schneider (js@joergschneider.com)
+ *
+ * Developed with the assistance of:

+ * This driver attempts to support the Lexar Jumpshot USB CompactFlash

+ * a USB-to-ATA chip.
+ *
+ * This driver supports reading and writing. If you're truly paranoid,
+ * however, you can force the driver into a write-protected state by setting
+ * the WP enable bits in jumpshot_handle_mode_sense. See the comments
+ * in that routine.
