I agree with Don that it sounds like a power cable or power supply  
problem.  The only way I can think of that would involve the USB  
connector or the CI-V connector would be that the fuse in the negative  
side of the IC-7000's power cable is blown.

If this fuse is blown (negative side only) the radio's ground return  
would be completed via the CI-V to USB cable's ground return.  This  
cable is large enough to handle the receiver's current demand but not  
the transmitter's.  Do not continue to operate if this fuse is blown  
as it will a larger load on the USB jack's wiring than it was designed  
to handle.... possibly damaging the Mac.

Just my thoughts.
