CW hickups when using USB cables

I am using an external keyer (Winkey) with my 6700 on v1.10.16.91 with a 4 port FTDI Serial port Adapter attached to the USB port.
I've had random CW hickups (every 15 seconds or so there are dropouts or prolonged dits - two dits would become a dah) in my CW sidetone for a few weeks now - apparently since I've changed my Station Automation over to USB cables outputting the frequency to my other devices in the shack.

I've just tried disabling both my USB cable ports and - voila - the CW is steady as always.

Can anybody confirm this or is this already tracked as an issue? I couldn't find it in the forum here.

Hi Eric, thanks for coming back.

I've now exchanged the 4 port adapter by two individual FTDI adapters.

I can confirm the issue has gone when switching to two individual FTDI cables.

The FTDI cables really should all be the same from a hardware point of view as long asĀ  they use proper and original chips.

And the question still remains, how an issue on the USB side of things could possibly affect CW generation. So even though the problem is gone you still might want to have your developers look at it.
Anyway thanks for the input guys and I am glad I'm back to smooth and nice QRQ.
