Experiencing intermittent CAT data flow to/from my Flex 6500

Bob KN4HH

I am using a Flex 6500 to interface with a SPE Expert 1.3K and a AT-Auto tuner.  I am experiencing a condition where after a few minutes of use, the CAT data flow between all three units ceases.  The only remedy I have found is to go to the USB menu and disable then  enable both USB ports.  Any comments or suggestions would be appreciated.

I had a similar problem and it was resolved by adding snap-on ferrites to the USB cable ends. HTH.

You might want to look at the power settings for your USB devices in Windows.  Go to the Control Panel and select Device Manager.  Find the USB devices at the bottom of the listings and open it.  Find your USB devices that affect your amp and double click on each.  Select the Power Management tab and make sure the item "Allow the computer to turn off this device to save power" is NOT checked on the affected devices.  Also, in your Power Settings under Windows Settings, click on "Additional power settings" under the Related Settings heading.  Click on "Change plan settings" for your current power plan and click on the "Change advanced power settings" at the bottom of the next window.  Click on the + next to "USB settings" then on the + next to "USB selective suspend settings" and make sure both items are set to "Disabled" to assure that your USB devices aren't going to sleep.  You may have to experiment with which devices and settings affect your situation.

The USB connections are between the radio's USB and the SPE. The USB settings you referred to are for the PC's USBs.

Sorry, I didn't understand the setup.. Should have known they were the radio's USB ports.  That's what I get for being a computer-oriented guy - always looking at the computer end of things!

Ignore my comments regarding the PC's USB ports.  I didn't realize your were dealing with the radio's USB ports out to the amp and tuner.  WX7Y's suggestion regarding a powered USB hub connected to the radio is a good, though.

Many thanks, guys for the suggestions. I will definitely go the station powered usb hub route. I have other instances of overloading usb ports so I understand what you are saying.. Greg, thanks for your suggestion. My bad for not specifying which USB ports were being used. I am always grateful for any and all inputs. That is what is so great about this community. Thanks again and 73, Bob, KN4HH
