115  * The AMI virtual floppy device is not a real USB storage device, but
116  * emulated by the SP firmware shipped together with important Sun x86
117  * products such as Galaxy and Thumper platforms. The device causes
118  * very long delay in boot process of these platforms which is a big
119  * performance issue. Improvement in firmware may solve the issue, but
120  * before the firmware is fixed, it needs to be taken care of by software
121  * to avoid the huge impact on user experience.
122  *
123  * The long boot delay is caused by timeouts and retries of READ CAPACITY
124  * command issued to the device. The device is a USB ufi subclass device
125  * using CBI protocol. When READ CAPACITY command is issued, the device
126  * returns STALL on the bulk endpoint during the data stage, however, it
127  * doesn't return status on the intr pipe during status stage, so the intr
128  * pipe can only fail with timeout.
129  *
130  * Reducing timeout value to 1 second can help a little bit, but the delay
131  * is still noticeable, because the target driver would make many retries
132  * for this command. It is not desirable to mess with the target driver
133  * for a broken USB device. So adding the device to the scsa2usb blacklist
134  * is the best choice we have.
135  *
136  * It is found that the READ CAPACITY failure only happens when there is
137  * no media in the floppy drive. When there is a media, the device works
138  * just fine. So READ CAPACITY command cannot be arbitrarily disabled.
139  * Media status needs to be checked before issuing the command by sending
140  * an additional TEST UNIT READY command. If TEST UNIT READY command
141  * return STATUS_GOOD, it means the media is ready and then READ CAPACITY
142  * can be issued.
143  *
144  * SCSA2USB_ATTRS_NO_MEDIA_CHECK is added below for this purpose. It is
145  * overrided in scsa2usb.c for the AMI virtual floppy device to take care
146  * of the special need.

163  *		Mitsumi's CD-RW devices.
164  * SCSA2USB_ATTRS_BIG_TIMEOUT: Mitsumi's CD-RW devices need large
165  *		timeout with SCMD_START_STOP cmd
166  * SCSA2USB_ATTRS_RMB: Pay attention to the device's RMB setting,
167  *		instead of automatically treating it as removable
168  * SCSA2USB_ATTRS_USE_CSW_RESIDUE: Some devices report false residue in
169  *		the CSW of bulk-only transfer status stage though data
170  *		was successfully transfered, so need to ignore residue.
171  * SCSA2USB_ATTRS_NO_MEDIA_CHECK: AMI Virtual Floppy devices need to
172  *		check if media is ready before issuing READ CAPACITY.
173  * SCSA2USB_ATTRS_NO_CAP_ADJUST: Some devices return total logical block number

177  * and recovers then it will not be added to the scsa2usb_blacklist[] table
178  * in scsa2usb.c. The other attributes will not be taken of the table unless
179  * their inclusion causes a recovery and retries (thus seriously affecting
180  * the driver performance).
