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> 21 * 22 * This program is free software; you can redistribute it and/or modify it 23 * under the terms of the GNU General Public License as published by the 24 * Free Software Foundation; either version 2, or (at your option) any 25 * later version. 26 * 27 * This program is distributed in the hope that it will be useful, but 28 * WITHOUT ANY WARRANTY; without even the implied warranty of 29 * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

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. 46 */ 47 48 #include <linux/errno.h> 49 #include <linux/module.h> 50 #include <linux/slab.h> 51 52 #include <scsi/scsi.h> 53 #include <scsi/scsi_cmnd.h> 54 55 #include "usb.h" 56 #include "transport.h" 57 #include "protocol.h" 58 #include "debug.h" 59 #include "scsiglue.h" 60 61 #define DRV_NAME "ums-jumpshot" 62 63 MODULE_DESCRIPTION("Driver for Lexar \"Jumpshot\" Compact Flash reader"); 64 MODULE_AUTHOR("Jimmie Mayfield <mayfield+usb@sackheads.org>"); 65 MODULE_LICENSE("GPL"); 66 67 /* 68 * The table of devices 69 */ 70 #define UNUSUAL_DEV(id_vendor, id_product, bcdDeviceMin, bcdDeviceMax, \ 71 vendorName, productName, useProtocol, useTransport, \ 72 initFunction, flags) \ 73 { USB_DEVICE_VER(id_vendor, id_product, bcdDeviceMin, bcdDeviceMax), \ 74 .driver_info = (flags) } 75 76 static struct usb_device_id jumpshot_usb_ids[] = { 77 # include "unusual_jumpshot.h" 78 { } /* Terminating entry */ 79 }; 80 MODULE_DEVICE_TABLE(usb, jumpshot_usb_ids); 81 82 #undef UNUSUAL_DEV 83 84 /* 85 * The flags table 86 */ 87 #define UNUSUAL_DEV(idVendor, idProduct, bcdDeviceMin, bcdDeviceMax, \ 88 vendor_name, product_name, use_protocol, use_transport, \ 89 init_function, Flags) \ 90 { \ 91 .vendorName = vendor_name, \ 92 .productName = product_name, \ 93 .useProtocol = use_protocol, \ 94 .useTransport = use_transport, \ 95 .initFunction = init_function, \ 96 } 97 98 static struct us_unusual_dev jumpshot_unusual_dev_list[] = { 99 # include "unusual_jumpshot.h" 100 { } /* Terminating entry */ 101 }; 102 103 #undef UNUSUAL_DEV 104 105 106 struct jumpshot_info { 107 unsigned long sectors; /* total sector count */ 108 unsigned long ssize; /* sector size in bytes */ 109 110 /* the following aren't used yet */ 111 unsigned char sense_key; 112 unsigned long sense_asc; /* additional sense code */ 113 unsigned long sense_ascq; /* additional sense code qualifier */ 114 }; 115 116 static inline int jumpshot_bulk_read(struct us_data *us, 117 unsigned char *data, 118 unsigned int len) 119 { 120 if (len == 0) 121 return USB_STOR_XFER_GOOD; 122 123 usb_stor_dbg(us, "len = %d\n", len); 124 return usb_stor_bulk_transfer_buf(us, us->recv_bulk_pipe, 125 data, len, NULL); 126 } 127 128 129 static inline int jumpshot_bulk_write(struct us_data *us, 130 unsigned char *data, 131 unsigned int len) 132 { 133 if (len == 0) 134 return USB_STOR_XFER_GOOD; 135 136 usb_stor_dbg(us, "len = %d\n", len); 137 return usb_stor_bulk_transfer_buf(us, us->send_bulk_pipe, 138 data, len, NULL); 139 } 140 141 142 static int jumpshot_get_status(struct us_data *us) 143 { 144 int rc; 145 146 if (!us) 147 return USB_STOR_TRANSPORT_ERROR; 148 149 // send the setup 150 rc = usb_stor_ctrl_transfer(us, us->recv_ctrl_pipe, 151 0, 0xA0, 0, 7, us->iobuf, 1); 152 153 if (rc != USB_STOR_XFER_GOOD) 154 return USB_STOR_TRANSPORT_ERROR; 155 156 if (us->iobuf[0] != 0x50) { 157 usb_stor_dbg(us, "0x%2x\n", us->iobuf[0]); 158 return USB_STOR_TRANSPORT_ERROR; 159 } 160 161 return USB_STOR_TRANSPORT_GOOD; 162 } 163 164 static int jumpshot_read_data(struct us_data *us, 165 struct jumpshot_info *info, 166 u32 sector, 167 u32 sectors) 168 { 169 unsigned char *command = us->iobuf; 170 unsigned char *buffer; 171 unsigned char thistime; 172 unsigned int totallen, alloclen; 173 int len, result; 174 unsigned int sg_offset = 0; 175 struct scatterlist *sg = NULL; 176 177 // we're working in LBA mode. according to the ATA spec, 178 // we can support up to 28-bit addressing.
