Corsair K100 and TBT200 issue

[Ryan9x]

I'm a fan of corsair, so corsair always is the first choice for me.
Recently, I upgrade my rig to new level and is able to use thunderbolt4, and bump, corsair TBT200 come to my life.

 

I plug all peripherals to this dock:

1 virtuoso se receiver usb to connect to my headset and sabre pro wireless mouse.

1 k100 usb cable (the signal cable)

1 k100 usb cable (the usb downstream cable) (1)

they are connected directly to TBT200

 

1 m55 pro

1 webcam

1 hdmi cable

they are connect via an external hub (Ugreen 60557)

 

My rig is using gigabyte z790 ud ax mobo and I have gc-maple brigde AIC to enable the thunderbolt 4 support, everything seems work fine at the first time.

But when I switch from my pc to my laptop. (my dell laptop have two thunderbolt 4 port and I'm using one port for power supply)

The problem shows up.
The keyboard does not work, no light no key stroke. I have to unplug and plugin the keyboard to TBT200 to make it work.

This issue only happens with the keyboard, the other peripherals work correctly.

When I switch back to pc, the issue happens again, I have to do the same thing: unplug and plugin again.

The issue also happens when I turn off the TBT200 and turn on it again (by press the power button on TBT200 for about 5 seconds).

I have created a support ticket: 2006230567
But there is no response for now.

 

My workaround is connect the keyboard to the external hub (Ugreen 60557), not directly to TBT200, it works in almost time. But I don't like that. I spent money for corsair and don't want to workaround like this.

This is so annoying, and make me disappoint because the TBT200 and K100 are so expensive in my country. I don't expect this issue happens with these high-end peripherals.

 

Hope that corsair support team read this topic and response.
Thank you.

Have you updated your KB Firmware to the latest? It is a know issue that this KB has disconnection issues, it however resolved with the latest firmware.

Hey,

I just came across your post, but you might wanna follow the thread here: K100 disconnection issues

Just from looking at your screenshot, you are running a very old firmware version for the K100.

You might be affected from the firmware update hold that Corsair put in place a while ago.

So yes in short support must take a look into this.

Hope I did help you in some way 🙂

Oh, You just remind me about the firmware.

I clicked "Check for Updates" button in iCue and there is no update available. And I can't find the new firmware

Sorry if my comment "in short support must take a look into this" was confusing, but I meant with to contact Corsair Support again (or send a reminder) and explain to them you are running very old firmware on your particular K100 unit.

Hope they can take a look into it and supply you with the correct firmware.
