I have: Ubuntu (Linux) Mythtv V30 in home build box, USB IR receiver, URC-7130 essence R02, Logitech K120 wired keyboard in use, RM, RMIR, RMPB, Bookmarked web site https://www.mythtv.org/wiki/Programming_Remotes_as_Keyboards , JP1 Adapter and JP1.2/1.3 (FLASH) USB Cable for Universal Remotes. I can start RMIR but when I select download(I presume from remote) it says 'no remote found'. Adaptor is at ttyUSB0 and it is listed in the USB devices(lsusb). I have tried all 4 different combinations of cable and adaptor, with and without batteries in the remote. What setting am I missing in RMIR? Any other clues could help.

In RMIR, trying explicitly setting the serial port:

Remote > Interface > JP1.X Serial...

Choose Other and enter ttyUSB0

I may be wrong or misreading this

But are you using a JP1 adapter in addition to the JP1.x cable?
If so, then you should leave the JP1 adapter out and only use the cable to connect to the remote. The reason why is becuase you have a JP1.3 (I think) remote

/dev/ttyusb0 is rw for the dialout group which I am in, so thats out.
I have tried the cable without the adaptor, both ways and with and without batteries. No joy.
The board in the remote is labelled as jp1-4(not jp1.4), if this means anything.
Thanks rem and greg.

If your remote is JP1.4, you definitely should NOT be using the legacy JP1 adapter.

Sorry The Robman. I repeat that it is labelled 'jp1-4' not jp1.4. I have not heard of the URC-713x series being jp1.4. It is about 3 years old, could it be?

For the UK remotes, I notice the JP1.x socket within the battery hatch will be shaped like an AA battery symbol/shape.
So Pins 5&6 will are on the end with the notch and pins 1&2 are on the flat end.
Eg using the AA battery shape pins 5&6 will be the +ve end, pins 1&2 on the -ve end.
ie from a vertical view
Code:
------
|1  2|
|3  4|
|5  6|
  ||
or from a horizontal view
Code:
   ========
  = 5 3 1 |
  = 6 4 2 |
   ========

You mention diygadget.com in an earlier post, so I tried looking it up to see what you're working with
https://www.diygadget.com/remote-control-accessories tutorials
http://www.tiaowiki.com/w/Home TIAO Product Tutorials
http://www.tiaowiki.com/w/JP1,_JP1.1,_JP1.2_and_JP1.3_Cable_for_Remote_Control_Tutorials FAQs JP1, JP1.1, JP1.2 and JP1.3 Frequently Asked Questions

Top image shows the pin assignments on the connector

There are 2 USB JP1.x cables at diygadgets.com
One is a FTDI type, the other is not. I wonder if there are functional differences between them when used in Linux?

The cable I use in Linux Mint is the 'original USB FTDI' bought from ebay as mentioned in this forum, so I am using an FTDI type in Linux Mint.
Original 6Pin FTDI FT232RL USB to TTL RS232 Serial Adapter Cable for Arduino - select the independant head option
http://www.hifi-remote.com/forums/viewtopic.php?t=16360

So when I check the messages after connecting the cable I see this
Code:
lsusb
Bus 003 Device 004: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC

sudo lsusb -v -s 3:4
Bus 003 Device 004: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC
Device Descriptor:
  bLength                18
  bDescriptorType         1
  bcdUSB               2.00
  bDeviceClass            0 (Defined at Interface level)
  bDeviceSubClass         0
  bDeviceProtocol         0
  bMaxPacketSize0         8
  idVendor           0x0403 Future Technology Devices International, Ltd
  idProduct          0x6001 FT232 USB-Serial (UART) IC
  bcdDevice            6.00
  iManufacturer           1 FTDI
  iProduct                2 FT232R USB UART
  iSerial                 3 AK05CYLZ
  bNumConfigurations      1

Anyway - these are my suggestions in no particular order
Make sure you know which way the connector goes - if possible try another remote
Check your cable works by using another machine/pc
Eg you may wish to try another machine
a windows machine or
another Linux pc or
boot from Live Linux http://www.hifi-remote.com/forums/viewtopic.php?t=2895&start=88 which starts at
