Hi Marrion,

I wanted to inform you that I am currently using the Logitech M185 mouse, which features a single USB receiver for both the mouse and keyboard.

r/sysadmin on Reddit: Lenovo Hybrid USB-C with USB-A Dock Firmware Utility crashing fix
February 25, 2026 -

Hello everyone,

considering I've been troubleshooting this issue for about four days now, I thought it would be nice to have this in the public domain should someone need it.

This is related to the driver "fhybd1042_1_w10w11", a firmware update for Hybrid Lenovo Docking Stations, crashing upon being opened. As much as I'd like to heroically recall the last few days of this infuriating struggle, I'll just get to the point:

It's WINS.

Specifically, the utility calls IPHLPAPI to parse network adapters, but fails at freeing the heap where that list is stored due to a corrupted entry. It turns out, whatever happens in this process cannot handle more than 2 WINS servers being configured.

So, if you have multiple entries under "Secondary WINS-Server" in ipconfig, reconfigure DHCP until you only have ONE primary and ONE secondary, and the problem is fixed.

Cheers.

r/thinkpad on Reddit: Lenovo have taken down the firmware for the ThinkPad USB-C Gen 2 Dock
January 12, 2025 -

It seems as if Lenovo has removed the firmware for the USB-C Gen 2 dock. https://pcsupport.lenovo.com/gb/en/accessories/acc500106

The support page is still up, however scrolling down to Drivers and Software, and then clicking the firmware button provides the following link:

http://pcsupport.lenovo.com/us/en/downloads/DS539092

This redirects to a page not found.

Is anyone aware of where to find the firmware for the dock? This is pretty frustrating!
