KVM not working after windows update

October 1, 2015  Windows 10 just did an update and now 3 of my Windows 10 systems do not recognize my keyboard or mouse on the KVM using USB for the mouse and keyboard.   The TRENDNET console TK-407K is a 4 port  KVM and worked just prior to the Windows update today.  Have reverted to a Windows XP system to write this note.  Problem occurred on all Windows 10 builds 10240 and both 32bit and 64 bit FASTRING systems build 10547.

Have removed all September 2015 updates and USB connections are still not working unless they are direct connected and not using KVM Console.  Started seeing USB not recognized earlier in September but did not put 2 and 2 together to mean that my USB's were getting corrupt data.  Now I remember putting in a USB 16GB thumb drive and system said that it looks like the device is not supported.

dzimmerl,

   Did you ever figure out your issue?  I had this problem affect a laptop after an update some time back.  Shortly after I found some servers also had applied some updates and the same issue started happening.  Now, none of my systems work on the switch.  This was all post a system receiving an update.

I am highly confident that functionally nothing has changed with the switch itself, it is still operating nominally.  If I'm sitting at an unused port, I can use the keyboard to select a new port no problem.  If that port contains an affected system, the keyboard no longer responds and I need to manually switch it.

Just installed Windows 10 build 14361-160603-1700 and KVM stopped working with USB mouse and keyboard on 1 non fast ring system, 1 32 bit fastring system and 1 64 bit fast ring system.  Tried to repair USB through powering systems down and 64 bit fastring system bit the dust for some reason.  Have spent over 10 hours trying to bring it back to life.

After having the same problems, started months ago, I recently found a string that referenced some tech called:
  • DDM (Dynamic Device Mapping) Technology for USB reliability and immediate device recognition when switching

Apparently, Microsoft implemented something that has to do with refreshing connected devices or something (sorry, read this a few days ago).

So, not sure yet if the KVM's no longer working is related, but I've had all my Windows 10's stop working on my IOGear MiniView PRO (gcs1108 I believe).  I couldn't find anything referencing DDM on the IOGear, but at the price I'd expected it to always work.

Anyways I've ordered a ConnectPRO UD-18+, 8-Port USB/DVI KVM Switch.  It's details reference this technology and so I've got my fingers crossed.
