I have a Flex 1500 with the keyer locking up randomly. Has anyone else had this problem? The techs
My Flex 1500 keyer keeps locking up randomly during cw transmission and I need to stop and start the PowerSDR program to get back to normal operation. But it will randomly happen again. Has anyone else had this problem.

Those are the FLEX-1500 drivers and have nothing to do with which USB controller the FLEX-1500 is connected to. All that tells you is the FLEX-1500 is powered on (FlexRadio USB Kernel driver) and that the PC sees it as a USB device.
You need to use USBDeview to determine which USB controller the 1500 is connected to and if other USB devices are sharing the same controller.
USBDview did not indicate a usb controller connection for the Flex 1500. The Flex is plug into a usb 3.0 port and aside from the cw problem everything else works very well especially sideband voice. All outstanding audio reports using a 100 watt amp.
Now you had not previously provided the critical piece of information that you are using a 100W amp. If the radio locks up when you are using the amp, then I agree with Howard that RFI is your most likely issue.
It was originally on a usb 2.0 port but I experimented with usb 3.0 in both cases the same result. The cw issue occurs whether I am using the amp or not, no difference observed in the random cw lockup.
Off to bed shortly yawn !
Installed a stand alone USB card in the PC but that had no positive effect on the cw lockups. Went to using a old MFJ 422D external keyer and have had no cw lockups after an hour and half of cw sending into a dummy load. I think I'll stick with the external keyer.
