How to send USB Bulk zero length packet?
2005-12-21 09:08 PM
To end a bulk in transfer, either the data packet is less than maximum or a zero length packet has to be transfered.
How do I transfer a zero length packet? If I set the buffer count to zero, no transmission ocurs. The problem is only present when I transfers an amount of data, which is a multiply of 64 eg. 512 bytes. Then if I do that twice, then it appears as one bulk transfer of 1024 bytes, on my USB analyzer. Best regards, Frank Andersen
