I am unable to connect the USB on my K3, modified with a KIO3B set of boards, to my MacMini, running OS10.9.5. I am not able to connect it to my MacbookPro running Sierra, 10.12.3, either. My Macs simply do not see the USB port. If I look at the “About This Mac” report on the Macs, I see that a “General Purpose USB Hub” is connected when the USB cable from the K3 to the Apple products is connected. I have made sure I have the latest drivers. I have tried different USB cables. I have Googled and can not find an explanation or a solution. I have done several system resets. Occasionally when I plug the USB cable into the Mini, but not the Pro, I get a message “USB Devices disabled - please disconnect the device drawing too much power” - doing that seems to do nothing. But I understand the KIO3B draws only 90ma and the Mini puts out 500ma.
Elecraft has told me that they have users who have Macs and KIO3B working. Has anyone have a suggestion what I should do to fix this? The KIO3B boards were installed by Elecraft so I assume it left the factory working, although I have not ruled out a short or defect in the board that may have occurred . I have not tried the K3/board with a Windows computer but the same thing happens when I try to find the ports on Windows10 in Bootcamp. Thanks in advance for any help.
