Subject: Eliminate EP1, commands should use EP0.
X-Git-Tag: sigrok-firmware-fx2lafw-0.1.0~78
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=4ad20a4c57699f7ea5ce88fc132feaf7471743c1;p=sigrok-firmware-fx2lafw.git

Eliminate EP1, commands should use EP0.

The protocol should be implemented using control requests of type
'vendor-specific' (bmRequestType[6:5] = 2).
