Icom USB Driver Reinstall Windows 10 Troubleshooting HRD and WSJT-X

The culprit to many ongoing troubles has been the Windows Icom USB driver. One of the last Windows 10 updates caused many Hams to have problems and it seems the problems can reoccur too. If troubleshooting steps fail, do an Icom USB driver reinstall. Before the USB driver reinstall, have a look at a few critical areas that may be causing problems in Ham Radio Deluxe, Digital Master and WSJT-X. A proper Icom USB driver reinstall may be necessary in the end. There was a microphone privacy setting that appeared to be problematic for some. Have a look at it first and look at my troubleshooting steps and video below.

Note: In this article I am referring to a station that uses only a USB cable. This article does not include use of a CI-V cable for rig control.

HRD and Digital Master Troubleshooting

If you're having trouble connecting with HRD, most of the time it is either the com port and/or baud rate that is not set correctly. If the USB cable has been moved or a new driver installed, sometimes the com port number changes in Windows.

With Digital Master, most of time it comes down to a small problem like the Soundcard setting. The USB Audio CODEC is no longer listed as the Soundcard in Digital Master.

If your radio and software had been working fine, those are some items to check first. See thumbnails below (click for a larger image) and see the video below.

WSJT-X Troubleshooting

This one can be equally as tricky.

If the connection will not work when the Test CAT button is clicked in the WSJT-X> Settings>Radio tab, it can be a problem with the Serial Port and/or Baud Rate. Similarly if the Test PTT does not work it can be a problem with the PTT Method.

HamLib Error in WSJT-X: Try restarting your computer before installing the HamLib software. For me it is usually an issue with Serial Port or Baud Rate in WSJT-X. Other Hams have reported to me that installing the HamLib software (Ham Radio Control Libraries) fixes the problem. 

Icom USB Driver Reinstall

As always, disconnect the USB cable between the computer and the radio before installing the driver.

This is pretty straight forward and not difficult to accomplish. First we want to uninstall whatever version of the software package we have installed and then reinstall the latest version. You'll find the links below to the USB driver download and the Installation Guide. This is the first item covered in the video below.

Other Troubleshooting Steps

You can shut down everything and move the usb cable to a different physical USB port on your computer. Then power things up. Check what com port the cable is on after doing so.  You could also try using a different USB cable.

Lastly, RESTART occasionally  🙄

There are two USB ports on the rear of the Icom 7610. Use the USB2.0 not the blue USB3.0.

I'm an Amateur Radio enthusiast. I love the hobby and experimenting with radios, antennas and software. On my YouTube channel I upload videos on the Icom 7300 and Icom 7610 along with Ham radio software programs. I hope to inspire people to try new things in Amateur Radio.

I have been trying to download and install the HamLib Amateur Radio Control Libraries. The files down load and save on my Windows 10 drive but when I try to install the software I get error messages that it cannot open the files to write them. Very frustrating.

Hi Rich ;
Being a new owner/op of a 7610 have much appreciated your tips/tricks in getting the conductivity going…
with that said… I’m NOT! ha . some reasonable success with HRD… and not so much with WSJT-X…Many of the same HamLib error reads as others… very frustrating… 3rd day into configuring the 7610…
any clues are appreciated.

Hi Rich,

I have watched several of your videos on YouTube but I am having a problem with the USB driver that came with RS-BA1. When I click connect on the Radio Screen or turn on the radio while the computer is running I get a message The Last USB driver loaded failed or something like that. I am having issues with transmitting remotely and have yet to get it working correctly. I have uninstalled and followed the instructions to install the USB drivers correctly.
Another question is will I be able to use this USB driver to run WSJT-X or another digital program?

Thanks very much,

Hello Rich,

My problem is with the IC-7600. When I plug the cable into the USB-B port – the back of the radio to any USB port on computer, the IC-7600 simply stops transmitting. I use Windows 10.

Wow, the last Windows 10 update (2004) did a number on many app settings. IC-7300 communications was now inop. The driver uninstall/reinstall did the trick. Thanks!

Hi Rich- I really enjoy your channel. I have finally ran into a quandary that I cannot figure out, and I have not found anyone who can point me in the right direction to solve the problem. I have an IC-7300 and am trying to work WinLink/VARAHF. However I cannot get the computer driver that I downloaded from Icom (SiliconLabs CP210x) to make the radio transmit/tune. Device Manager tells me that the “driver requires further installation”. In the events tab, I am given an Error 430 and 20003.
I have uninstalled and re-installed the driver 20+ times and 20+ different ways, and have looked at all the advice you gave here, but to no avail. How do I “further install” the driver? Do you have any other rabbit holes you can point me to? Thank you for your great content.
Best and 73.

Hi Rich- I really enjoy the content on your channel and blog. Always informative and easy to understand. 
I have a driver problem that I am unable to fix though, even after following all of your tips and pointers in this article and video “Icom USB Driver Reinstall Windows Troubleshooting HRD WSJT X”..
I have downloaded the IC-7300 driver (Silicon Labs CP210x) for Windows 10 and I cannot get the driver to transmit to the radio.
I have un-installed and re-installed the driver software countless times, in various different ways, and have updated my Windows 10 to current standards.
I have also looked at all the tabs for the mic and the permissions, etc., but no matter what I try, I keep getting a message (in the Device Manager) that this driver “requires further installation (Event 430 and 20003)”.
Do you have any idea how I can further install this driver?
Thanks again for all the great videos on YouTube and great articles on your blog.
Best and 73,
Lance KI5HHK
