How can I test USB ports on 6600M?

julie
julie Member
I'm connecting a SteppIR SDA 100 controller (top data connector) directly to my new 6600M using the S-12 cable and an RT Systems (RT-3) USB to Serial converter.  Problem is the 6600M does not see the cable on the USB port.  Also tried another USB to Serial converter (cheapo eBay via China adapter) with no joy.

Is there a way I may test the USB connectors to make sure they are working and it's not a cable / USB to Serial converter problem?

Many, many thanks for any input or suggestions.

    Flex USB Ports only have support for FTDI Chip set devices and cables.

    I was wondering what would happen if you plugged a ICOM RC-28 remote encoder into a 6600M flex radio??? I know Flex has their own remote encoder,, but I have a RC-28 sitting on the shelf....

    Larry ... thank you for the link and the kind words.  :)  I had already read that doc a couple times and done quite a bit of testing on the cable to ensure the correct pin-outs.

    Bret ... both the USB to Serial adapters I've tried are FTDI devices, but of course there are about a million flavors of those.  :P

    Robert ... sorry, but I have no idea on the RC-28 at this point.

    So thank you all for the help, but the question remains "How do I test the USB port functionality?"

    This problem is resolved.  First off a thank you to all who commented and assisted ... especially to Larry, KE2YC who took the time to patiently explain to me over the land line that not all FTDI chips are equal.  :)

    Larry also gave me a great deal of information to get me started with my new Flex radio ... so thank you again Larry!

    Now for the fix:  One must use the "correct" FTDI Chip Set adapter as it apprears that not all FTDI chips work with the Flex radio.  I tried three USB to Serial adapters and only the Ugreen one was recognized by the 6600M.  So I put each one of the adapters on a rpi3 and used the "dmesg | grep usb" command to look at the chipset they were using.  I believe the key lines that "tell the tale" are these:

    RT Systems adapter (does not work with Flex):
    [   60.492165] usb 1-1.4: Product: USB <-> Serial
    [   60.492172] usb 1-1.4: Manufacturer: FTDI
    [   61.565496] usb 1-1.4: Detected FT232BM

    Cheapo china adapter (does not work with Flex):
    [   60.492165] usb 1-1.4: Product: USB <-> Serial
    [   60.492172] usb 1-1.4: Manufacturer: FTDI
    [   61.565496] usb 1-1.4: Detected FT232BM

    Ugreen USB 2.0 to RS232 DB9 Adapter Cable (FTDI) (This one works)
    [    2.484371] usb 1-1.4: Product: FT232R USB UART
    [    2.484385] usb 1-1.4: Manufacturer: FTDI
    [    2.484405] usb 1-1.4: SerialNumber: A906U5TE
    [    4.314332] usb 1-1.4: Detected FT232RL

    Here's the amazon link to the good one:

    Another day, another lesson learned.  :)

    a lot of cheep cables that say there FTDI aren't a real FTDI chipset cable, I think the key is the "FTDI chipset with Full hardware Handshake" in the description some where. 

    Here is a NULL MODEM that works for a lot of Devices that require a Null Modem cable. 
    https://www.amazon.com/gp/product/B06XG6S7YQ/ref=oh_aui_detailpage_o01_s01?ie=UTF8&psc=1

    Most of the time the cheep ones DON't work, the real FDTI chipset cabels cost about $16.00 and up.

    For a standard RS-232 cable, I have only use the REAL FTDI Branded cables like Flex sells so not sure of a amazon cable part number.

    OH These China Adapters!! I got a new Lenovo 2 in 1 laptop computer for my ham gear...  Went a got a Lenovo USB-C to USB 3.1-SD card Hub.. Everything worked like a champ but the cable from the adapter is very short..

    So I went on line , eBay, and got a USB-C 8" extension... So this is a simple Male to Female USB-C extension.. I mean how complicated can this be!!!! It said it was good for Power, Video, Data, etc.  When it arrived it did not work... My USB ports on the hub would not work, but the green LED on the Hub lit up!!! The seller felt it was a defective unit, so they sent me another one, same issue!!!!

    So I went to Amazon and found an extension, but noticed a lot of negative reviews???

    The reviews basically said the same thing that I was experiencing, would not work on a USB-C hub!!  I know a lot about needing High Speed, 18GB certified HDMI cables from my 4K HDR player to my AVR and from the AVR to the 4K HDR TV set. Without these high end cables, I could not get YouTube 4K HDR to work... But a regular HDMI cable would work fine from my 4K Player to the TV set... This had me scratching my head till I took ma deep dive into why YouTube was different then playing a 4K movie...

    Once I had the correct cables, took 3 tries,,, My TV set went into HDR mode, all was good... I am presuming that these USB-C cables are missing some internal wires... BTW, thanks for the heads up on the FTDI Chip Set that works!!!

    Always some sort of challenge when you pair up a 12AT7 or 6BA6 against 21,000 lines of code!!! LOL

    Happy Easter folks,, wife is calling, dinner time

    I had the same problem.  I have literally a drawer full of usb - serial adapters and none of them worked.  I bought a Ugreen and it works perfectly.

    Thank you

    The radios only work with Genuine FTDI chipsets, not the knock-offs.
