Have a USB flash drive floating around, and not sure of it's capabilites? I just ran into that same exact issue, though with a brand new USB flash drive that's a really kewl 500GiB double-ended thumb-type drive, one end the standard USB-A connector, and the other end, an iPhone "Lightning" connector! Perfect for me with all my iPhones, iPads, and over 74 computers just in my house!

So, here's a simple one-liner to find out how fast it will run at, which is all I really wanted to kmnow at this immediate moment in time! Here it is:

[]$ sudo lsusb -vvv | grep operate

And here is the output of the above command, showing the speeds the device is capable of operating at:

can't get debug descriptor: Resource temporarily unavailable
      Device can operate at Full Speed (12Mbps)
      Device can operate at High Speed (480Mbps)
      Device can operate at SuperSpeed (5Gbps)
can't get debug descriptor: Resource temporarily unavailable
can't get device qualifier: Resource temporarily unavailable
can't get debug descriptor: Resource temporarily unavailable
can't get debug descriptor: Resource temporarily unavailable
can't get device qualifier: Resource temporarily unavailable
can't get debug descriptor: Resource temporarily unavailable
can't get debug descriptor: Resource temporarily unavailable
can't get device qualifier: Resource temporarily unavailable
can't get debug descriptor: Resource temporarily unavailable

You can totally ignore the lines starting with the word "cant", as they are meaningless. As you can see from the above output, the device can operate at "Full", "High", and "SuperSpeed"! Wonderful, I now know what I wanted. I hope you find that little tidbit useful. Of course, you do have to be a member of the "sudoers" group. So, on that note, why not create another little snippet on how to add a normal, already existing user account to the sudoers group, allowing them to "safely" run apps with eleveate administrator/root user privileges. I'll put it here: SUDO - Running commands and apps with elevated superuser/root/administrator privileges safely!


The, & web and email servers have been moved over to a new box that should provide much faster performance and more stability. Previously, the servers had been running on a very old VMWare server on my Fedora desktop.

I have also maxed out the RAM memory that my new Xeon based server motherboard is able to use, doubling it from 16GB to 32GB!

Please let me know if you experience any performance or other issues with any of my websites.

The best way to let me know is by email, @ Jamie at

VirtualBox provided for free by Oracle!!! Great VM solution which is totally free, unlike how VMWare has gone commercial, and is supposed to remain free forever. Better than VMWare in my tests and opinion, and is now being used to host all of my VM's, including this one running my Apache web server!
