That is the MaxPacket value for endpoint 0. The last two lines above show the MaxPacket values for endpoint 1. > I did a printk of this value for both endpoint 0 and 1 right at the > beginning of probe function and the values are 64.

Try sending just the first 100 KB of the channel 6 file and the first 200 KB of the dual-channel file. You can gzip them if you want; that should shrink them quite a bit.
