the front usb 2.0- ports on my dell inspiron 3847 are under-powered. I cannot use usb powered drives with them as I get data errors. The rear ports are fine. Those front ports are fine with older USB drives that have their own power supply brick...

on another machine, I have also experienced the phenomenon that a kobo (aura HD) is always recognised when connected via an (unpowered) USB hub, but is iffy with direct connect.

finally the device port itself can become problematic. My wife keeps handing back USB cables to me saying "this one does not work any more" ( but they test fine for me). It seems that the usb port on her Samsung S7 phone, is used every day for charging, does not grip tight onto all cables now.... so after 18 months , it is worn out? maybe time for a new phone soon as cost of a repair shop for a simple replacement socket is probably > current value of phone, and I can't do precision soldering or tricky dismantling
