IOGear KVM (GUD3C04) - No keyboard after switch to Ubuntu

th flag

I have an IO Gear KVM, model GUD3C04. Its connected over USB C to (1) Macbook via Caldigit TS3 docking station and (2) Intel NUC.

I have a Logitech MX Master for Mac Bluetooth mouse that works great on both Mac and Xubuntu. However, my USB keyboard (Logitech K740) that's plugged into the KVM refuses to work on Xubuntu after I switch from the Mac (it works going from NUC to Mac).

How I get it working is unplug the USB A keyboard from the KVM, plug into the NUC, hit a key, then plug it back into the KVM. From there, it works great, until I switch from the NUC and back to it.

It seems as though Xubuntu doesn't recognize the keyboard until I "wake" it with a keystroke while directly plugged in.

Where do I start? I've tinkered with some CLI settings about a year ago, it didn't work, and I can't remember what those settings were - but it was something with xorg or input devices. I abandoned the troubleshooting and have been living with it since. IOGear's recommendation was to update the drivers in Windows. I do not have a Windows machine, and not sure how doing that would help me on Xubuntu.

Anyways, where should I start? I'm happy to post back any output here to the forums to help troubleshoot.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
