Hi there,

I'm happy to report that libftdi seems to be alive with the synchronous
bitbang mode on the FT240X without any changes.

With the FT240X eval board from FTDI:

ugen0.4: <FTDI UMFT240XE> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps)
pwr=ON (90mA)

  bLength = 0x0012
  bDescriptorType = 0x0001
  bcdUSB = 0x0200
  bDeviceClass = 0x0000  <Probed by interface class>
  bDeviceSubClass = 0x0000
  bDeviceProtocol = 0x0000
  bMaxPacketSize0 = 0x0008
  idVendor = 0x0403
  idProduct = 0x6015
  bcdDevice = 0x1000
  iManufacturer = 0x0001  <FTDI>
  iProduct = 0x0002  <UMFT240XE>
  iSerialNumber = 0x0003  <FTWCC5QB>
  bNumConfigurations = 0x0001

The bitbang.c example appears to work. What changes, if any, would be
needed to make it an officially supported device?
