KVM USB Wake Issues
-
I'm having some issues with many of our KVM's not waking machines up. A full reset of the KVM is necessary to rectify the situation.
I've tried Uninstalling/reinstalling USB drivers, adjusting the settings for USB sleep and the like in Power settings, but no success.
One of the computers is not allowed to have the sleep settings adjusted because of security stuff, so that's not an option.
I've read about the issue being linked to our KVM's being emulated instead of Dynamic Device Mapping?
Is anyone out there using ConnectPro KVM's? With the presence of DDM, do they truly not have this issue?
With the issue being re-enumeration of USB ports, I'm wondering if anyone out there has written a computer wake re-enumeration script or anything fancy to deal with this issue. Please if anyone knows of such a thing or a possible workaround let me know. Going to play around in Windows Task Scheduler for a bit and see if anything is possible that way...

Have not used a KVM in well over a decade, I'm afraid.

@scottalanmiller Elaborate if you would, kind sir.

I've had this same issue in Fedora 29 workstation. I cant seem to remember it being an issue before the upgrade to 29. Although, it is a weird issue and my VMs are just used for testing so I cannot say for sure.
I have had them just show black screens and not wake up at least 20 different times where I had to do a hard reset. I wish I had more info, but these are just test boxes so I havent cared too much.
Sorry I was no help

I think you are talking about KVM Virtualization, I think @G-I-Jones is talking about KVM as in keyboard / video / mouse extenders and switches.

Assuming you mean the old KVM (keyboard switch) not KVM the virtualization, that's not something I've used since 2003 or so, and even then it was on legacy 1990s gear. Always used built in OOB management since right around 2001.

This is a ConnectPro KVM

This suggests that the issue is with the ConnectPro and not the computers. Can you patch the ConnectPro itself?
-
@scottalanmiller we don't use ConnectPro, we use Trendnet TK-214i's. I only mentioned ConnectPro because as I understand, they pretty much run the DDM game. Forget I asked though because after some product reviews, and a look at the price tags, it wasn't going to happen even in the worse case scenario.
I figured out that the CAC reader keyboards were present in every case so I've done away with those for the people affected most frequently by it. So far so good, but time will tell.

Little two port KVMs? Why? Why not use remote access like Screen Connect or MeshCentral? or RDP, etc...
-
@Dashrender separate networks. (gov/commercial)

We constantly had issues with them switching between PCs. Our solution was mainly to give dual monitors and the KVM only switched keyboard and mouse. So we bought cheap tripplite ones.
-
I've never seen that problem and I've used plenty of KVMs.
Does it work the way it should without the KVM switch in between? Then I think your KVMs are probably sh*te.

So that's the story on how you became a java expert

LOL oops

Why can't sleep be disabled, and they just be set to lock after 5 minutes of inactivity?
-
@IRJ I know right. The powers that be on the gov network said they won't allow it.

Yeah, sleep is so often such a problem.

The upside then, is, that you have someone to blame and say "this is how it works, this was their decision to have this issue." Wash hands, walk away.
