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): https://www.trinityos.com/HAM/CentosDigitalModes/hampacketizing-centos.html#...
Permanent USB recognition across reboots (this example is for one of RT Systems cables for a Yaesu FT857):
https://www.trinityos.com/HAM/CentosDigitalModes/hampacketizing-centos.html#... -- #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", ENV{ID_MM_DEVICE_IGNORE}="1", RUN+="/usr/local/sbin/RTSystems-addports.sh &" SUBSYSTEM=="tty", ATTRS{idVendor}=="2100", ATTRS{idProduct}=="9e56", SYMLINK+="ft857_prog" --

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

Anyone using any of the Amazon clones successfully? I will be using Ubuntu so most of the driver issues are not a problem.
