1 /* Driver for Lexar "Jumpshot" Compact Flash reader
2 *
3 * jumpshot driver v0.1:
4 *
5 * First release
6 *
7 * Current development and maintenance by:
8 * (c) 2000 Jimmie Mayfield (mayfield+usb@sackheads.org)
9 *
10 * Many thanks to Robert Baruch for the SanDisk SmartMedia reader driver
11 * which I used as a template for this driver.
12 *
13 * Some bugfixes and scatter-gather code by Gregory P. Smith
14 * (greg-usb@electricrain.com)
15 *
16 * Fix for media change by Joerg Schneider (js@joergschneider.com)
17 *
18 * Developed with the assistance of:
19 *
20 * (C) 2002 Alan Stern <stern@rowland.org>

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.
