127  * The AMI virtual floppy device is not a real USB storage device, but
128  * emulated by the SP firmware shipped together with important Sun x86
129  * products such as Galaxy and Thumper platforms. The device causes
130  * very long delay in boot process of these platforms which is a big
131  * performance issue. Improvement in firmware may solve the issue, but
132  * before the firmware is fixed, it needs to be taken care of by software
133  * to avoid the huge impact on user experience.
134  *
135  * The long boot delay is caused by timeouts and retries of READ CAPACITY
136  * command issued to the device. The device is a USB ufi subclass device
137  * using CBI protocol. When READ CAPACITY command is issued, the device
138  * returns STALL on the bulk endpoint during the data stage, however, it
139  * doesn't return status on the intr pipe during status stage, so the intr
140  * pipe can only fail with timeout.
141  *
142  * Reducing timeout value to 1 second can help a little bit, but the delay
143  * is still noticeable, because the target driver would make many retries
144  * for this command. It is not desirable to mess with the target driver
145  * for a broken USB device. So adding the device to the scsa2usb blacklist
146  * is the best choice we have.
147  *
148  * It is found that the READ CAPACITY failure only happens when there is
149  * no media in the floppy drive. When there is a media, the device works
150  * just fine. So READ CAPACITY command cannot be arbitrarily disabled.
151  * Media status needs to be checked before issuing the command by sending
152  * an additional TEST UNIT READY command. If TEST UNIT READY command
153  * return STATUS_GOOD, it means the media is ready and then READ CAPACITY
154  * can be issued.
155  *
156  * SCSA2USB_ATTRS_NO_MEDIA_CHECK is added below for this purpose. It is
157  * overrided in scsa2usb.c for the AMI virtual floppy device to take care
158  * of the special need.

170  *		Clik!/MemoryStick/MMC USB readers/writers.

175  *		Mitsumi's CD-RW devices.
176  * SCSA2USB_ATTRS_BIG_TIMEOUT: Mitsumi's CD-RW devices need large
177  *		timeout with SCMD_START_STOP cmd
178  * SCSA2USB_ATTRS_RMB: Pay attention to the device's RMB setting,
179  *		instead of automatically treating it as removable
180  * SCSA2USB_ATTRS_USE_CSW_RESIDUE: Some devices report false residue in
181  *		the CSW of bulk-only transfer status stage though data
182  *		was successfully transfered, so need to ignore residue.
183  * SCSA2USB_ATTRS_NO_MEDIA_CHECK: AMI Virtual Floppy devices need to
184  *		check if media is ready before issuing READ CAPACITY.
185  * SCSA2USB_ATTRS_NO_CAP_ADJUST: Some devices return total logical block number
186  *		instead of highest logical block address on READ_CAPACITY cmd.

188  * NOTE: If a device simply STALLs the GET_MAX_LUN BO class-specific command
189  * and recovers then it will not be added to the scsa2usb_blacklist[] table
190  * in scsa2usb.c. The other attributes will not be taken of the table unless
191  * their inclusion causes a recovery and retries (thus seriously affecting
192  * the driver performance).
