[chirp_users] Chirp and Icom IC-7200

[Bill]

Ok so I am wanting to use chirp to upload memories to my Icom IC-7200 
Amateur Radio. Now the IC-7200 has a USB and a CIV connection. My 
understanding is that the USB should work, But I cannot seem to get it 
to work.  I do not have a CIV cable. So does anyone have any experience 
with the IC-7200? Can I use the USB connection to upload memories? Or am 
I going to need a CIV cable?
Thanks Bill
