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

160  *		timeout with SCMD_START_STOP cmd
161  * SCSA2USB_ATTRS_RMB: Pay attention to the device's RMB setting,
162  *		instead of automatically treating it as removable
163  * SCSA2USB_ATTRS_USE_CSW_RESIDUE: Some devices report false residue in
164  *		the CSW of bulk-only transfer status stage though data
165  *		was successfully transfered, so need to ignore residue.
