It looks like your device reports incorrect residue values (the "R 4096" above). This means that it violates the USB Mass Storage protocol specification. Mac OS X and Windows ignore the bogus residue values but Linux doesn't. If you provide the necessary device information (the entry in /proc/bus/usb/devices or output from "lsusb -v") then a blacklist entry could be created to work around the device's shortcomings.
