Hello,
as told by unusual_devs.h I send this mail to request the inclusion of a
new quirk for my D-Link DNS-313 NAS I use in USB mass storage mode.
Since linux-3.3 (IIRC), the device didn't work anymore because of the
use of READ_CAPACITY_16 SCSI command. The device prepends its reply with
two bytes that prevents a good size detection. With my patch (or
dynamically with quirks set to "2310:6688:e") it works perfectly.
I hope everything is ok with my patch. I don't have
/proc/bus/usb/devices anymore, so I paste below the output of lsusb -v
and I hope it will be a good replacement.
I also have a wireshark/usbmon dump of the bad exchange between host and
faulty device if you need it.
Regards,
Philippe Valembois
