I also have a USB 3.0 Hard Drive Enclosure that is properly recognised in the USB 3.0 ports without the above problems. Just once, today, I managed to demount, remove and reconnect the drive to the same USB 3.0 port and it was recognised again as a USB 3.0 device (must have been a fluke). The only way make to make sure it is recognised as a USB 3.0 device, in Linux, was to have it in a USB 3.0 port when the Operating System was started. Sometimes I get a "not running at top speed connect to a high speed hub" in the output from dmesg when it is connected to a USB 2.0 port. So, I thought I would try this in the Linux environment but no success with switching between a USB 2.0 and USB 3.0 port as in Windows.
Sometimes, just demounting and removing from the USB 3.0 port and connecting it again to the USB 3.0 port, without any use in a USB 2.0 port, has the same effect.Īlso, if the Flash drive is in a USB 3.0 port, when Windows is started, it is recognised as a USB 3.0 device. So, after I connected the drive to a USB 2.0 port, demounted and removed it and then connected it to a USB 3.0 port, 3 times, Windows recognised the drive as being a USB 3.0 device again. So, I started looking for solutions to reset a USB Flash drive so that it was recognised as a USB 3.0 Device. Prior to this I had thought that UNetbootin had corrupted the drive in some way.
This could occur after the USB Drive was plugged into a USB 2.0 port and whether, or not, files were copied to the drive. In Windows, I was able to repeat the problem of a USB 3.0 Flash Drive not being recognised as a USB 3.0 device in a USB 3.0 port. Ok then, over the last few days, I've discovered some annoying things going on in both the Linux and Windows environments. I only just tried this before starting to compose this post. I had a few uncomfortable minutes with that because I forgot to "update-grub" again after I reset /etc/default/grub to its original state. First thing I want to make mention of is that using "pci=nomsi" disabled all of the USB controllers/connections.
