I am working on Debian Stable Linux which is otherwise working very well.
The machine/motherboard details are as follows:
Machine:
Type: Desktop
Mobo: Intel
model: DH61BF
v: AAG81311-102
BIOS: Intel
v: BFH6110H.86A.0009.2013.0715.1155
date: 07/15/2013
The desktop hardware summary via inxi
is as follows:
$ inxi
CPU: Dual Core Intel Core i3-3220 (-MT MCP-)
speed/min/max: 2035/1600/3300 MHz
Kernel: 5.10.0-18-amd64 x86_64
Up: 15m
Mem: 1489.5/3830.1 MiB (38.9%)
Storage: 1.82 TiB (2.7% used)
Procs: 184
Shell: Bash
inxi: 3.3.01
However, the machine's USB ports are working erratically and sometimes the USB flash drive connected to them does not show up.
When I switch on my printer connected to it, it does not connect and I get following output on command sudo dmesg
. (It used to connect and work perfectly earlier).

I have tried to attach printer to 3 available USB ports on the desktop and it does not work on any of these.
Is this problem in USB port hardware or software? How can this problem be solved?
Edit:
I opened the PC and saw that there are 4 USB ports at the back attached directly to the motherboard. In addition, there are two USB ports in the front, attached to the motherboard with a cable. All connections seemed tight.
I found that only one USB port is working properly, which is connected to USB mouse of the desktop, while all other 5 are not working. I attached a USB splitter/hub to this working USB port and connected mouse, printer and USB flash drive to it. Now all these are working all right.
It seems there is some problem in motherboard itself and I will need to replace it once this working USB port also stops working!
