Subject: USB: ftdi_sio: Use jtag quirk for Arrow USB Blaster
Date: Wed, 11 Apr 2018 17:05:13 +0300	[thread overview]
Message-ID: <20180411140513.3740-1-vvavrychuk@gmail.com> (raw)

Arrow USB Blaster integrated on MAX1000 board uses the same vendor ID
(0x0403) and product ID (0x6010) as the "original" FTDI device.

This patch avoids picking up by ftdi_sio of the first interface of this
USB device. After that this device can be used by Arrow user-space JTAG
driver.
