Did you install the usb driver?  If not make sure that is done first.  

What signals are you trying to pick up? Voice or digital?  
If digital you probably want something like UZ7ZHO sound modem. There are many videos on the internet on how to set that up.  

Perhaps you can provide more details.

Dear all, 

Please we have an icom-9100 connected to an antenna yagi which is controlled by GS-550 auto-tracker. My objective is to track satellites, I tried to read signals from the radio through the usb interface but always I received only noise even when disconnecting the usb and listening to the icom. I would like to read signals from satellites though the UHF band. I bought HRD software but always had the same problem. 
Please what can I do? 
Is there any online service or a freelancer that can assist me?
Thank you. 

kind regards
Kais
