I figure it would be useful to have a master list of working KVM switches since I see quite a few topics about them (being of particular interest to me this is probably a biased dataset). I’ll start:
Make: Terived
Model: TH41-3
Working: Yes
Computers Supported: 4
Rack mount: No
Hotkey Support: Working with storage on the Comet disabled and port plugged into the KVM’s Keyboard Port (mouse works), broken without
I upgraded to a KVM switch with 8 ports (probably overkill) just because it’s rack mountable. Luckily, this one works just as well ([HOME], [HOME], [channel number] is the hotkey in this case). This switch is also nice in that it has two keyboard/mouse ports so I don’t need the little USB 2-port hub attached and then the Comet Pro arrives I can get rid of the HDMI splitter (see this post for details).
Make: MT-Viki
Model: MT-0801HK
Working: Yes
Computers Supported: 8
Rack mount: Yes
Hotkey Support: Working with storage on the Comet disabled and port plugged into the KVM’s Keyboard Port (mouse works), broken without
Note that there seem to be weird race conditions, sometimes rebooting the KVM switch causes the video and keyboard to stop working unless I disconnect the HDMI out and USB keyboard. This is a switch issue and not a Comet issue, it happens with my lapdock as well.
Do the shortcuts work if you setup a shortcut to do ctrl-ctrl-#-enter? I can’t seem to get this to work, but it does work if I bring up a virtual keyboard and do it.
Benefits over this KVM vs the other KVM I was trying in the post above, this one lets you change channels even if signal isn’t detected (so that you can wake a system up). I could not do this with the other one.
I currently don't have access to that model, but IIRC it behaved as my current one does - try omitting the . Note that you may not be able to use the Comet Hotkey feature for this, it seems to be sending simultaneous keys instead of a sequence separated by time.
