So first of all - when you remove the MI_01 entry it is possible to
install and use the Virtual COM port with drivers from FTDI. The
original .inf files don't need any additional changes.
About Duane's idea. A script is still not needed. The basic thing is
that FT2232 has two channels and for each of them the system has to have
some kind of driver. When the device is "JTAG-only" (second channel
unused) than the inf file for libusb should contain entries for both of
them. When the device has a UART/RS-232 port on the second channel, the
inf file for libusb should only contain ONE entry, for first channel -
this way system (and the user) will have to look for the driver
somewhere else (original inf file for FTDI).
So:
When a dongle is "JTAG-only"
User has to add total of FOUR lines to the .inf file:
"{name}"=LIBUSB_DEV, USB\VID_{vid}&PID_{pid}&MI_00
"{name}"=LIBUSB_DEV, USB\VID_{vid}&PID_{pid}&MI_01
When a dongle has JTAG and RS-232/UART
User has to add only TWO lines to the .inf file:
"{name}"=LIBUSB_DEV, USB\VID_{vid}&PID_{pid}&MI_00
The above line/lines (with filled {} elements) should go info [Devices]
and [Devices.NT] group, that's why the numbers are doubled.
I'll post a changed inf file in a moment.
4\/3!!
