[PATCH] USB: don't send any MODE SENSE commands to usb mass storage devices
This patch basically eliminates the use of MODE_SENSE or MODE_SENSE_10 for
direct-access USB storage devices. That $&%*! command has caused us more
trouble than all the others combined, and after more than a year we still
don't have a good way of handling/using them.
I constantly get complaints about devices which don't work because of the
way 2.5/6 uses MODE_SENSE and MODE_SENSE_10 -- this patch will greatly
increase compatiblity with devices. As with the patch to limit transfer
sizes, I'd like to see this applied as soon as possible.
