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

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

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