The device causes 127 * very long delay in boot process of these platforms which is a big 128 * performance issue. Improvement in firmware may solve the issue, but 129 * before the firmware is fixed, it needs to be taken care of by software 130 * to avoid the huge impact on user experience. 131 * 132 * The long boot delay is caused by timeouts and retries of READ CAPACITY 133 * command issued to the device. The device is a USB ufi subclass device 134 * using CBI protocol. When READ CAPACITY command is issued, the device 135 * returns STALL on the bulk endpoint during the data stage, however, it 136 * doesn't return status on the intr pipe during status stage, so the intr 137 * pipe can only fail with timeout. 138 * 139 * Reducing timeout value to 1 second can help a little bit, but the delay 140 * is still noticeable, because the target driver would make many retries 141 * for this command. It is not desirable to mess with the target driver 142 * for a broken USB device. So adding the device to the scsa2usb blacklist 143 * is the best choice we have. 144 * 145 * It is found that the READ CAPACITY failure only happens when there is 146 * no media in the floppy drive. When there is a media, the device works 147 * just fine. So READ CAPACITY command cannot be arbitrarily disabled. 148 * Media status needs to be checked before issuing the command by sending 149 * an additional TEST UNIT READY command. If TEST UNIT READY command 150 * return STATUS_GOOD, it means the media is ready and then READ CAPACITY 151 * can be issued. 152 * 153 * SCSA2USB_ATTRS_NO_MEDIA_CHECK is added below for this purpose. It is 154 * overrided in scsa2usb.c for the AMI virtual floppy device to take care 155 * of the special need. 156 */ 157 #define MS_AMI_VID 0x46b /* VendorId of AMI */ 158 #define MS_AMI_VIRTUAL_FLOPPY 0xff40 /* PID for AMI virtual floppy */ 159 160 /* 161 * List the attributes that need special case in the driver 162 * SCSA2USB_ATTRS_GET_LUN: Bulk Only Transport Get_Max_Lun class specific 163 * command is not implemented by these devices 164 * SCSA2USB_ATTRS_PM: Some devices don't like being power managed. 165 * SCSA2USB_ATTRS_START_STOP: Some devices don't do anything with 166 * SCMD_START_STOP opcode (for e.g. SmartMedia/CompactFlash/ 167 * Clik!/MemoryStick/MMC USB readers/writers. 168 * SCSA2USB_ATTRS_GET_CONF: SCMD_GET_CONFIGURATION is not supported 169 * SCMD_TEST_UNIT_READY: for floppies this needs to be converted to 170 * SCMD_START_STOP as floppies don't support this 171 * SCSA2USB_ATTRS_GET_PERF: SCMD_GET_PERFORMANCE not supported by 172 * Mitsumi's CD-RW devices. 173 * SCSA2USB_ATTRS_BIG_TIMEOUT: Mitsumi's CD-RW devices need large 174 * timeout with SCMD_START_STOP cmd 175 * SCSA2USB_ATTRS_RMB: Pay attention to the device's RMB setting, 176 * instead of automatically treating it as removable 177 * SCSA2USB_ATTRS_USE_CSW_RESIDUE: Some devices report false residue in 178 * the CSW of bulk-only transfer status stage though data 179 * was successfully transfered, so need to ignore residue. 180 * SCSA2USB_ATTRS_NO_MEDIA_CHECK: AMI Virtual Floppy devices need to 181 * check if media is ready before issuing READ CAPACITY. 182 * SCSA2USB_ATTRS_NO_CAP_ADJUST: Some devices return total logical block number 183 * instead of highest logical block address on READ_CAPACITY cmd. 184 * 185 * NOTE: If a device simply STALLs the GET_MAX_LUN BO class-specific command 186 * and recovers then it will not be added to the scsa2usb_blacklist[] table 187 * in scsa2usb.c.
