I'm having a problem with very slow USB 3.0 ports. It's taking about half an hour to transfer only 200MB or so.
I also have some very strange output in dmesg:

You may share your kernel.config and version via pastebin url here.
you may check those usb options in your kernel. I think xhci or what it iscalled is needed and some others
you may provide lspci --kk; lsusb
You may check with a livecd, like sysrescue-cd if that issue happens too
you may check if the hardware is fine, => test it with sysrescue-cd, and visual inspectino of ports and cables / connections => usb cables lack on quality these days, |
