KVM Mouse Buttons Fail after Yosemite Upgrade

I have several computers attached to an Avocent 8030 IP KVM. Prior to upgrading to Yosemite from Mavericks, the KVM worked flawlessly. After upgrading to Yosemite, I have location control, but no mouse button click control through the KVM. I have been able to reproduce on three systems. The first was a current model Mac Pro, the second was a mid-2010 Macbook Pro. Both worked previously but now do not. I have an existing last-gen i7 Mini that hasn't been upgraded and still works when plugged in with the same dongle and port.

Has anyone else seen this behavior with a KVM? My assumption is that the OS is handling third-party mice differently in this version. I'm hoping there is a setting I can change on the Mac side to restore the previous behavior.

Mac Pro, OS X Yosemite (10.10)

Still having this issue under El Capitan. This is extremely frustrating when dealing with a cluster of mac pros connected to a KVM. Any updates/solutions out there??

You might want to consider starting a new discussion. Since this one is a couple of years old, less people are likely to look at it. You can link to this one. Start a post in the El Capitan community.

I installed USBOverride and rebooted my Mac. The mouse problem has been solved. You can find the software here:
