Why are flash drives in yellow USB sockets not detected?

Question

USB

The essence of the problem. There are two yellow USB sockets on the back of the computer. We include a flash drive in any of them. An unknown USB device appears. We put firewood for USB, the flash drive is determined. We extract the flash drive, it does not matter if it is correct or not. Insert flash drive. An unknown USB device appears. We set the length for USB, the flash drive is detected again. And so every time, it is worth pulling out the flash drive and inserting it again, it is not determined until you reinstall the firewood. Everything works fine in black USB sockets. It does not depend on the type of flash drives.

Answer 1

two yellow USB sockets

We can assume that this is USB-3.0. But every USB-3.0 I've seen has blue plastic, not yellow. So it is highly desirable to clarify what kind of USB it is.
But let's say it's really 3.0. As you know, in 3.0 there are exactly the same 2 signal lines as in 2.0 (for backward compatibility with 2.0), and 4 more lines have been added to provide ten times the data transfer rate. They are served by a separate controller that requires a separate driver. In my practice, there were cases when the USB-3.0 plug worked normally with 3.0 flash drives, and refused to work with 2.0 flash drives - it is obvious that there in the controller the part that is responsible for 3.0 was in good order, and responsible for 2.0 - dead.
Your case seems to be the reverse - 2.0 is OK, but 3.0 is not. Try to put the drivers on USB-3.0 anyway - it won't get worse, the driver falling off on 2.0 may stop.
