[Elecraft] MICROHAM USB III INTERFACE WITH K3 UTILITY DOES NOT WORK
I agree that the MicroHAM interface works perfectly with the Elecraft utility for everything except firmware updates. Using it with firmware updates is a disaster, don't ask me how I know this:) John KK9A From: Joe Subich, W4TV Date: Fri Feb 16 20:40:25 EST 2018 I have not attempted to run the P3 utility through microHAM USB Device Router but have no need to do so. Whenever I update the firmware in either of my K3(s) or the P3, I switch to a direct serial connection. 73, ...

Use of the K3 utility though any software router is not recommended and you might brick your K3. That being said, VMWare fusion will pass all USB ports through to the Windows 7 virtual machine. You must first plug them into the Mac OS and make sure they work there. Then you start up your virtual machine and make sure you have enabled and connected the USB devices in the VMWare settings (I think there is a tab on the top to do so.) If this is not done, then no ports are available.

Re: [Elecraft] MICROHAM USB III INTERFACE WITH K3 UTILITY DOES NOT WORK
Have you installed microHAM USB Device Router in the Windows Virtual Machine? Router installs both the FTDI (hardware) driver and the Eltima VSPAX (software) driver. The hardware driver is responsible for communications between the Router software and the interface. The VSPAX is responsible for creating the virtual COM port (as well as mapping rig control/CAT to one virtual port, and PTT, CW/FSK to a different virtual port if needed). 73, ...
