lsusb does report a 3.0 root hub. What makes you believe otherwise?

When I put a USB 3.0 stick in a USB 3.0 port, it does not show in Dolphin under the list of active partitions and drives. That is the only place I have found USB connections in the past. When I put a USB 3.0 stick in a USB 2.0 slot, it appears in that column of drives in Dolphin.

Is a USB hub the place I install a USB stick or the connection to the motherboard? I am not familiar with the term USB hub yet and have probably been using the term incorrectly in the past and still been understood? I have been calling the place you plug the USB stick in "port", an assumption on my part. Shab

On a 2013 post on ubuntu forums, it says some folks fixed it by adding "blacklist uas" to the /etc/modules/blacklist.conf file.

**Shabakthanai** · Apr 13, 2016, 02:01 PM

Hi, my friend, I did not have the file you mentioned in my computer. I had a 'modules-load.d' but that is the only file that contained the word 'modules'. I opened it anyway to see if there was anything relating to blacklist, and there was not. Thanks for the input. The information I got was more current, March 2015. There were a great number of posts confirming the same problem, but no one replied with a solution.

I don't think this had anything to do with recent work being done on my computer, but it may relate to the K16.04 installation. I looked in the BIOS and all USB connections seem to be appropriately entered.

Ooops, you are correct there's no more /etc/modules/blacklist.conf. Blacklisting is now done (in Debian) in /etc/modprobe.d. There I have a file named intel-microcode-blacklist.d and it reads like this:

Code:

# The microcode module attempts to apply a microcode update when
# it autoloads.  This is not always safe, so we block it by default.
blacklist microcode

I'm not sure whether *buntus are using /etc/modeprobe.d or whether that directory you found /etc/modules-load.d is your equivalent. But you can (as root) make a blacklist file similar to mine and save it there, and see if anything changes.

# Make USB 3 work
blacklist uas

I created a /etc/modules file because there was none. I was in sudo dolphin at the time. I then attempted to make an /etc/modules/blacklist.conf file, but was unable to make it. If that worked I intended to make a file /etc/modules/blacklist.conf/blacklist uas - was I attempting to do the right thing when I failed? Thanks!

do not ever launch dolphin with "sudo" ,,,never , never , never ,,,,,,,,,,, use "kdesudo" allways.

you want to make the file in /etc/modprobe.d so it would look like this ,,,,,, /etc/modprobe.d/yourfile ,,,,,we do not know for shure if it will work like you expect but you can make it like this .

press alt+F2 to open krunner ,,,,,,,,, type "kdesudo kate /etc/modprobe.d/usb-uas-blacklist.conf" withought the quotes and press enter in the kate window that will open (after you type your password) copy and past this in it

Code:

# Make USB 3 work
blacklist uas

save the file and exit kate ,,,,,,reboot and test the usb ports with you usb3 stick .

Thanks for the criticism Vinny, I forgot that Dolphin was among the kdesudo applications. I opened krunner and typed in kdesudo kate /etc/modprobe.d/usb-uas-blacklist.conf>pressed Enter>entered my password>Kate opened with # Make USB 3 work (next line) blacklist.uas>then I restarted my computer. When the login screen appeared, the background of that screen was different. Grey - Blue - Purple>I entered my password and the system opened. I then opened Dolphin to see if my USB ports were recognized. They were not. I just edited my reply. I believe when I made it I was having diabetic problems, because what I had printed was not what happened, in fact when I attempted to re-do the command steps, when I got to the final step, the code you recommended was already there, so I am pretty sure I followed your instructions.

Every once in a while my sugars go below safe standards. When that happens, I usually don't even notice it, in fact, fortunately, when I go through things to do, because my life is in jeopardy, the last thing I usually try is to read my sugars. I am not thinking properly at the time. I know I had to do this recently and it is the only thing I can think of that may have affected my reply. I have carefully retraced my steps and included an accurate happening above. Although it did not get the desired result, I suspect the result of the trial leads to another conclusion. Thanks for your patience. Hopefully when superuser is required in Dolphin, I will remember to use kdesudo.
