In my current setup there is an IC-7300 that has been unable to transmit even 1W without dropping the USB connection. 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/B01N94D03Ehttps://www.amazon.com/StarTech-com-Mountable-Rugged-Industrial-Port/dp/B003AVPUZG/ref=sr_1_8?s=electronics&sr=1-8 Mike W9MDB
