Hi everyone. I'm working with CYC68013A chip using slave FIFO mode and bulk transfer.ezusb.sys driver is used as a device driver in PC. When PC sends data to device, for example 2 bytes i fill additionally to 512 bytes packet size. Bud does chip needs to read all 512 bytes from FIFO or only two bytes can be read? Also i need a documentation on ezusb.sys. Some thigs i don't understand. Does ezusb.sys has internal buffer for a packets and what happens to packets if device send them to PC but software does not read them using IOCTL_EZUSB_BULK_READ command? Thanks in advance.
