Subject: [usb] how to receive successive data after clear_feature()?

hi,
 I'm developing a  USB Mass Storage device, Bulk-Only protocol.
I use READ(10) command to get data. When bulk-in execute, the
host get "STALL". I use clear_feature to clear "STALL". After clear
_feature, next bulk-in command get a message "NAK", why?

My  clear_feature command :
Packet 1> SETUP from host to ADDR=0x08, EP = 0 
Packet 2> DATA0 (0x02 , 0x01 , 00 , 00 , 0x82, 00 , 00 , 00) from host 
Packet 3> ACK from device to Host 
Packet 4> IN from host to ADDR=0x08, EP = 0 
Packet 5> ACK from device to Host 

ps:My bulk-in command use EP=2 ADDR=0x08.

Is my method wrong? Or should I use other commands? 
Thanks a lot.
