Disable USB ports on Raspberry PI. What happened to raspberries?

Question

Raspberry Pi

Good afternoon. USB ports on Raspberry PI began to fall off. It looks like this - the USB drive is successfully disconnected message pops up, after a while the USB drive is connected and then this disconnection and connection is repeated. I have no idea what happened to the raspberries. 2-3 months ago it was less. At what point it appeared I will not say. Now every time you turn it on all the time. I changed the power supply, cleaned the connectors, I used different operating systems. The problem remains.

Answer 1

What are you feeding her? Maybe not enough current? In my case, after changing the charger, the ports stopped falling off.

Answer 2

Was it overheating? maybe something got soldered, swollen, etc.

Answer 3

Thank you for the quick response. Now the power supply from the PDA is HP hipro 5V 2A I tried another power supply. I bought a new HP 5V 2.1A. The food is ok. I thought maybe the 25Mhz quartz could be replaced. Not sure if it will help. I saw in the recommendations that there are problems with this quartz and in this case the usb ports do not work. It probably didn't overheat. I put radiators on the processor and memory, as well as on the stabilizer. I used Radial heat conductive adhesive. Maybe he got there, I don't know. There are no bulges or other signs of overheating on the board. I noticed that the voltage on the USB ports is 4.27 V. Without an SD card and mouse 5.05V, without a mouse 4.53V. Approximately such voltages with and without peripherals connected. I have not yet been able to measure the current consumption of raspberries.

Answer 4

faced the same problem on Raspberry Pi 3.
from the solutions found:
1. ground the usb heatsinks (probably meant about the usb port case)
2. update the kernel

sudo apt-get install rpi-update
sudo rpi-update
