I want to develop mass storage device using LPC2148.I am just referring code from Keil for USBMem. My problem is - I get Get_descriptor command from PC to which I respond with device descriptor. On receiving 8th byte it generates Reset. Then I get Set_address command. On response to it, I execute Set Address command in protocol engine. Then again I get Get_descriptor command (It should actually have index field of 18 but I receive with 64). Again after 8th byte it generates Reset and again gives Set_address command instead of Get_descriptor command for Configuration descriptor. What can be the problem?
Tsuneo, I agree! Bradford
