+# adapters (custom hw) based on the FT2232D chip.  The hardware is currently
+# under development; once it progresses past the vaporware phase, we are
+# going to submit a patch to the ftdi_sio driver in the Linux kernel to
+# recognize and handle this USB device similarly to several other already
+# existing UART+JTAG adapters of this kind, creating a ttyUSBx device
+# only for Channel B (UART), but not for Channel A (MPSSE JTAG).
+#
+# The distinctive custom USB ID will also help with the custom OpenOCD
+# configuration specific to our particular wiring of the reset and other
+# control signals that accompany JTAG, making our FreeCalypso UART+JTAG
+# adapter easier to identify among other FTDI-based USB devices.
