Ah, okay. Maybe the RequestType I'm sending it is wrong? Both uses my exact
model and somewhat describes the usb info in more detail.

It looks like the message for LEFT is:
#define ML_MAX_LEFT 0x04 /* 00 04 00 00 00 00 00 00 */
I change the code to:
dev.ctrl_transfer(0x21, 0x09, 0,0, [ 00,04, 00, 00, 00, 00, 00, 00])
But still got the pipe error.
