It is something with power management. Looks either like the device does not support it or maybe a kernel option is missing. https://learn.microsoft.com/en-us/windows-hardware/drivers/usbcon/common-hardware-problems-with-u1-or-u2-implementation https://marc.info/?l=linux-usb&m=139145094020655&w=2 _________________ My personal space My delta-labs.org snippets do expire PFL - Portage file list - find which package a file or command belongs to.
