+ Say Y here in order to have the USB Mass Storage code indicate to
+ the SCSI layer that using MODE SENSE(6) and MODE SENSE(10) to
+ determine if the media is write-protected is a good thing to do.
+
+ Many devices have historically had trouble with these commands,
+ hence the default 2.6.x behavior has been to suppress their use.
+ 2.4.x used these commands with (at best) mixed results, often
+ crashing the firmware of the device. However, the SCSI layer now
+ issues these commands in a manner more consistent with other
+ "popular" OSes, in an attempt to improve compatibility.
+
+ Saying Y here allows these commands to be sent to a USB device.
+ If you find a device this doesn't work for, switch to N and let
+ us know at usb-storage@lists.one-eyed-alien.net
+
+ If you say N here, the kernel will assume that all disk-like USB
+ devices are write-enabled.
