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

155  *		Mitsumi's CD-RW devices.
156  * SCSA2USB_ATTRS_BIG_TIMEOUT: Mitsumi's CD-RW devices need large
157  *		timeout with SCMD_START_STOP cmd
158  * SCSA2USB_ATTRS_RMB: Pay attention to the device's RMB setting,
159  *		instead of automatically treating it as removable
160  * SCSA2USB_ATTRS_USE_CSW_RESIDUE: Some devices report false residue in
161  *		the CSW of bulk-only transfer status stage though data
162  *		was successfully transfered, so need to ignore residue.
163  * SCSA2USB_ATTRS_NO_MEDIA_CHECK: AMI Virtual Floppy devices need to
164  *		check if media is ready before issuing READ CAPACITY.
