I am still struggling to solve the problem with the malfunctioning USB 3
port on a desktop running Debian.
I would be very grateful if someone could please give useful answers to the
following questions :-
(1) Can the desktop be safely rebooted, if needed, given the USB 3 problem?
If your desktop cannot be safely rebooted, the USB ports are the least
of your worries.
(2) Can the USB 3 problem be fixed in some way or is the port now
permanently unavailable?
That depends upon your hardware, your operating system, your software,
and/or your definition of "fixed".
(3) If the USB 3 port is unavailable, can the new portable hard drive be
used to do a back-up of the system from the USB 2 port currently occupied
by a card reader or is there any risk the card reader will be messed up
again afterwards ?
(On a previous occasion, a portable hard drive was plugged into this
USB 2 port in place of the card reader. The system issued a message
indicating the port was busy. The card reader was plugged back into the USB
2 port and it was then found that a card inserted into the card reader
could not be mounted).
Power down the computer. Disconnect everything except the keyboard,
mouse, monitor, and network cable. Boot the computer.
Connect one device at a time and test it thoroughly. Repeat for all
devices.
Post if you have problems. Please run the following commands and post
the console session -- prompt, command entered, output obtained:
# cat /etc/debian_version ; uname -a
# lsusb
# dmesg | grep usb
