Well, the subject pretty much says it all. In my quest to try and figure out why test 14 (control write) doesn't work with my EZ-USB board, I noticed that sometimes testusb reported no error even though the kernel log complained "byte 0 is 0 not 2" etc.
I did some testing with different count and size settings, and it turns out that testusb -t 14 runs fine for count 1 - 2 and size 2 - 64 bytes (with vary 1). For size 1 I get error 22; for count > 2 I get error 74 (and "ctrl_out verify failed" in the kernel log).
Anyone know what the problem might be or where to start digging?
