Windows 10: Win 11 crashes lenovo laptop with dockingstation usb-c gen 2 KMODE_EXCEPTION_NOT_HANDLED

Hi,my Lenovo Thinkpad E15 Gen 3 AMD crashes frequently with Dockingstations connected to it. I updated the firmware of the Dock, Windows and the Drivers according to Lenovo Vantage. I changed several supported Dockingstations and after a while, the system just crashes and leaves a BSD.The Debug files show the KMODE Exception error, but i cant really figure which driver might be responsible for this. I guess that its a Dock-Error, since the machine runs smoothly without any dock - but thats less of a solution. Thanks in advance for any help to figure this.************* Preparing the environme

How to distinguish USB 3.2 gen 2 (10Gb/s) and gen 2*2 (20Gb/s) by c# code?

We have a device and a new PC both support USB 3.2 gen 2*2, the transfer speed is about 1GB per second, it's faster than USB 3.2 gen 2.

I want to know how to distinguish it with USB 3.2 Gen 2, the difference is Gen 2 use single lane, and Gen 2*2 use double lane.

But how to get the lane number?

I checked the device property via USBTreeViewer, but there is no property to indicate the difference.

Any one can give some tips? Thanks very much.

C# is better, C++ code is also OK.

 

Why is my USB 3.1 gen 2 adapter (USB C Female to USB A Male) causing bottlenecking?

I recently picked up an SSD and enclosure with a built in USB Cable. CrystalDiskMark shows a >500MB/s read speed and >400MB/s write speed with a direct USB C connection to a USB 3.1 gen 2 port, so all good here.

But I also picked up these adaptors from amazon.co.uk to ensure I could connect the drive to more common USB type A ports. These adapters noted that they could handle the 10Gbit speeds of USB 3.1 gen 2, although they do note that when this is the case the "other side" (Type A side) runs at USB 2 speeds. Out of a lack of options I decided to give them a go nonetheless and the claim is true. But it's not as simple as saying "these must really just be USB 2 adaptors with a blue finish".

When using the adapter to connect the drive to a front panel USB 3.1 gen 1 port connected to the USB 3 motherboard header, the speeds are ~300MB/s and 400MB/s read and write respectively. So the adapter can handle high throughput but just can't when used in gen 1 or 2 ports on the IO panel of the motherboard itself. Maybe this is a motherboard issue...

Edit: Just verified this across 2 Desktop systems:

• Rear Motherboard IO (USB 3.1 gen 1 and gen 2) with adapter: ~40BM/s
  R/W
  
• Rear Motherboard USB C with no adapter ~500MB/s R and ~400MB/s W
  (full speed)
  
• Front panel IO connected to motherboard USB 3 header (gen 1) with
  adapter ~200MB/s R ~400MB/s W
  

What am I missing here? I have found only one adapter available that clearly states it has 10Gbit ports at either end but it's pricey so any alternative suggestions are welcome. Notably, it has a significant rectangle shape at the USB C side, maybe this is part of the explanation...? See below:

 

Intune and USB-C

We have USB-C dockingstation and when we add the portable to intune, the dockingstation works in half. Has anyone had this problem?
