@MacVette It's the same device, different software. Everything is identical USB wise.
@gudenau what about the buffer storage in your software. Can it handle the max packet size or the entire chunk of data? Are interrupts being used?
@MacVette The data is coming back different, for example 0xAA becomes 0x2A.
@gudenau does that happen if you memcpy() your buffer with zero after reading each chunk? Could the 0x2A be stale data?
@MacVette I'm effectively using read.
@gudenau does the read function return the number of valid bytes? I’m guessing you have to provide the read function with a buffer that’s at least as big as the configured value for max packet size. I would think the read would provide “n” chunks with max packet size and a final read of remaining data (unless there is other USB traffic causing delays).
@MacVette I'm just reading a byte at a time for now. I'm probably just going to have to do some lower level stuff to make this work.
@gudenau maybe reading single bytes cannot keep up with the transfer rate.
@MacVette The AA from the device is an ACK and it waits for a response. All the data is correct on the line.
