Hello,
I want to realize a Mass storage device in My custom board using USB0, and the emulation process seems successful.Then i replied to the PC for some SCSI command such as INQUIRY, READ CAPACITY,etc. The whole process was captured by Device Monitor, i saw the PC recieved the data repied, but when i send a CSW followed the data replied, the PC recieved 0 bytes. I checked the TXPKTRDY bit in PERI_TXCSR register, it was cleared automatically, but no transmit interrupt generated.
Anyone could give me some advises?
