1 /* 2 * Driver for Lexar "Jumpshot" Compact Flash reader 3 * 4 * jumpshot driver v0.1: 5 * 6 * First release 7 * 8 * Current development and maintenance by: 9 * (c) 2000 Jimmie Mayfield (mayfield+usb@sackheads.org) 10 * 11 * Many thanks to Robert Baruch for the SanDisk SmartMedia reader driver 12 * which I used as a template for this driver. 13 * 14 * Some bugfixes and scatter-gather code by Gregory P. Smith 15 * (greg-usb@electricrain.com) 16 * 17 * Fix for media change by Joerg Schneider (js@joergschneider.com) 18 * 19 * Developed with the assistance of: 20 * 21 * (C) 2002 Alan Stern <stern@rowland.org> 22 * 23 * This program is free software; you can redistribute it and/or modify it 24 * under the terms of the GNU General Public License as published by the 25 * Free Software Foundation; either version 2, or (at your option) any 26 * later version. 27 * 28 * This program is distributed in the hope that it will be useful, but 29 * WITHOUT ANY WARRANTY; without even the implied warranty of 30 * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Like many other USB CompactFlash readers, the Jumpshot contains 41 * a USB-to-ATA chip. 42 * 43 * This driver supports reading and writing. If you're truly paranoid, 44 * however, you can force the driver into a write-protected state by setting 45 * the WP enable bits in jumpshot_handle_mode_sense. See the comments 46 * in that routine. 47 */ 48 49 #include <linux/errno.h> 50 #include <linux/module.h> 51 #include <linux/slab.h> 52 53 #include <scsi/scsi.h> 54 #include <scsi/scsi_cmnd.h> 55 56 #include "usb.h" 57 #include "transport.h" 58 #include "protocol.h" 59 #include "debug.h" 60 #include "scsiglue.h" 61 62 #define DRV_NAME "ums-jumpshot" 63 64 MODULE_DESCRIPTION("Driver for Lexar \"Jumpshot\" Compact Flash reader"); 65 MODULE_AUTHOR("Jimmie Mayfield <mayfield+usb@sackheads.org>"); 66 MODULE_LICENSE("GPL"); 67 68 /* 69 * The table of devices 70 */ 71 #define UNUSUAL_DEV(id_vendor, id_product, bcdDeviceMin, bcdDeviceMax, \ 72 vendorName, productName, useProtocol, useTransport, \ 73 initFunction, flags) \ 74 { USB_DEVICE_VER(id_vendor, id_product, bcdDeviceMin, bcdDeviceMax), \ 75 .driver_info = (flags) } 76 77 static struct usb_device_id jumpshot_usb_ids[] = { 78 # include "unusual_jumpshot.h" 79 { } /* Terminating entry */ 80 }; 81 MODULE_DEVICE_TABLE(usb, jumpshot_usb_ids); 82 83 #undef UNUSUAL_DEV 84 85 /* 86 * The flags table 87 */ 88 #define UNUSUAL_DEV(idVendor, idProduct, bcdDeviceMin, bcdDeviceMax, \ 89 vendor_name, product_name, use_protocol, use_transport, \ 90 init_function, Flags) \ 91 { \ 92 .vendorName = vendor_name, \ 93 .productName = product_name, \ 94 .useProtocol = use_protocol, \ 95 .useTransport = use_transport, \ 96 .initFunction = init_function, \ 97 } 98 99 static struct us_unusual_dev jumpshot_unusual_dev_list[] = { 100 # include "unusual_jumpshot.h" 101 { } /* Terminating entry */ 102 }; 103 104 #undef UNUSUAL_DEV 105 106 107 struct jumpshot_info { 108 unsigned long sectors; /* total sector count */ 109 unsigned long ssize; /* sector size in bytes */ 110 111 /* the following aren't used yet */ 112 unsigned char sense_key; 113 unsigned long sense_asc; /* additional sense code */ 114 unsigned long sense_ascq; /* additional sense code qualifier */ 115 }; 116 117 static inline int jumpshot_bulk_read(struct us_data *us, 118 unsigned char *data, 119 unsigned int len) 120 { 121 if (len == 0) 122 return USB_STOR_XFER_GOOD; 123 124 usb_stor_dbg(us, "len = %d\n", len); 125 return usb_stor_bulk_transfer_buf(us, us->recv_bulk_pipe, 126 data, len, NULL); 127 } 128 129 130 static inline int jumpshot_bulk_write(struct us_data *us, 131 unsigned char *data, 132 unsigned int len) 133 { 134 if (len == 0) 135 return USB_STOR_XFER_GOOD; 136 137 usb_stor_dbg(us, "len = %d\n", len); 138 return usb_stor_bulk_transfer_buf(us, us->send_bulk_pipe, 139 data, len, NULL); 140 } 141 142 143 static int jumpshot_get_status(struct us_data *us) 144 { 145 int rc; 146 147 if (!us) 148 return USB_STOR_TRANSPORT_ERROR; 149 150 // send the setup 151 rc = usb_stor_ctrl_transfer(us, us->recv_ctrl_pipe, 152 0, 0xA0, 0, 7, us->iobuf, 1); 153 154 if (rc != USB_STOR_XFER_GOOD) 155 return USB_STOR_TRANSPORT_ERROR; 156 157 if (us->iobuf[0] != 0x50) { 158 usb_stor_dbg(us, "0x%2x\n", us->iobuf[0]); 159 return USB_STOR_TRANSPORT_ERROR; 160 } 161 162 return USB_STOR_TRANSPORT_GOOD; 163 } 164 165 static int jumpshot_read_data(struct us_data *us, 166 struct jumpshot_info *info, 167 u32 sector, 168 u32 sectors) 169 { 170 unsigned char *command = us->iobuf; 171 unsigned char *buffer; 172 unsigned char thistime; 173 unsigned int totallen, alloclen; 174 int len, result; 175 unsigned int sg_offset = 0; 176 struct scatterlist *sg = NULL; 177 178 // we're working in LBA mode. according to the ATA spec, 179 // we can support up to 28-bit addressing.
