Hi All.

[XPS 8950, Win11] I am using an old KVM switch (Trendnet TK-222DVK). It has external power. I have never had issues with it before on other machines. On my new XPS 8950, however, I am having intermittent problems. Sometimes I get the Win11 popup error "USB device not properly detected". Sometimes the KVM is properly detected at boot. Sometimes the KVM gets dropped after a wake/sleep cycle or KVM toggle. The KVM itself might be failing. However, observing the lights on the KVM suggests that the XPS 8950 USB might be undervolted at boot and/or wake/sleep cycles. I have turned off all power saving USB options in the Device Manager. This KVM does not have a driver. It is a simple USB passthru. I have tried all USB ports on my XPS.

I have ordered a new KVM, but this seems to me like either a hardware, a BIOS or an OS issue related to my XPS.

Has anyone else experienced similar intermittent USB issues on their XPS?
