USB flash may be died of "READ CAPACITY(16)". Could you collect more information about what's exactly happens with the device? Can you execute some camcontrol inquiry or camcontrol readcap commands after kernel misdetected size with "READ CAPACITY(16)"? If yes (device is still alive), could you run these commands (with proper device name) and send me the output files: camcontrol cmd da0 -E -v -c "12 00 00 00 80 00" -i 128 - > INQ.res camcontrol cmd da0 -E -v -c "9e 10 00 00 00 00 00 00 00 00 00 00 00 20 00 00" -i 32 - > RC16.result -- Alexander Motin
