Last time I checked, RT Systems cables use FTDI USB to Serial chips but
they are programmed with non-standard USB VID:PID to make them
"proprietary". If you look at http://www.linux-usb.org/usb.ids and
search for "RT Systems", you can see a short list of some known VID:PID
combinations that Linux will then load the FTDI kernel module and treat
the USB device as a serial port. For unknown ports, I don't know if you
can fake out Windows to recognize RT System cables as a standard serial
cable but you CAN do this with Linux for ANY VID:VID using either some
USB or UDEV tricks.
I wrote the following up some time ago to either temporarily or
permanently recognize the RT Cable and create a /dev/ft857_prog serial
device instead of a generically named /dev/ttyUSB0 device:
Temporary USB recognition (this example does this for a Timewave
Navigator device):

Permanent USB recognition across reboots (this example is for one of RT
Systems cables for a Yaesu FT857):

#Device #3 - RT Systems CT-62B 1-port USB to serial adapter
for FT817/857/897 (FTDI-based)
#
#NOTE: This adapter is NOT recognized by the Linux kernel as a
valid
# serial device. RT System does this ON PURPOSE so their
programming
# software will only work with their cables! You can
change these IDs
# if you wish with
http://www.ftdichip.com/Support/Utilities.htm#FT_Prog
#
# Alternatively, the following will run a script to poke
the RT Systems
# USB IDs into the kernel FTDI driver so it can recognize
the new
# device as a serial port.

BUS=="usb", SYSFS{idVendor}=="2100", SYSFS{idProduct}=="9e56",

Trying to avoid RT systems. Not sure if they will work with CHIRP or
if it is only for their software.

Looking at picking up a ft-65 but the scu-35 cable looks to be
out of stock with no eta. Anyone using any of the Amazon clones
successfully? I will be using Ubuntu so most of the driver
issues are not a problem.
