The 7300 has a USB B 2.0 FemaleYou also have to supply power to it from the cable.So that's why a hub in the middle is necessary.And the optical has USB B 3.0 Male along with the hub having USB B 3.0 Female and the hub supplies power as the optical doesn't pass power lines. Mike W9MDB

I have numerous rigs hooked up and lots of USB connections. The 7300 is well known for being RFI sensitive dropping CAT and Audio service. So I bought an optical USB cable, plugged it into a non-powered Startech hub, then ran a triplite cable to the rig. Now able to run full power without any problems. I'll be doing more investigation with a cheaper hub and adding more USB devices to this new hub. But the optical cable has a USB-B on one end and USB-A on the other. So do need a USB hub that takes a USB-B cable. Not a cheap solution but effective. https://www.amazon.com/dp/B01N94D03E https://www.amazon.com/StarTech-com-Mountable-Rugged-Industrial-Port/dp/B003AVPUZG/ref=sr_1_8?s=electronics&sr=1-8 Mike W9MDB _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel -- Landesleiter ÖVSV LV NÖ
