USB not working anymore - RPi 3

Tue May 02, 2017 5:49 pm

Whenever I connect any USB device it won't show itself when I execute lsusb. Even devices that used to work before.

lsusb

Code: Select all

Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
dmesg gives me a constant error of over-current

Code: Select all

................
[  220.596929] usb 1-1-port2: over-current change
[  220.852896] usb 1-1-port2: over-current change

[  222.644918] usb 1-1-port2: over-current change
[  222.900902] usb 1-1-port2: over-current change
[  223.156899] usb 1-1-port2: over-current change
[  223.412899] usb 1-1-port2: over-current change
[  223.668923] usb 1-1-port2: over-current change
I've appended max_usb_current=1 already to the /boot/config.txt as recommended in some other fixes, but that changed nothing. I am using a 5V 2.1A PSU and powering my Pi by the micro-USB connection. Powering it straight on the 5V pins with 1.9A gives the same result.

Anyone has some possible solutions for this problem? How can I use my USB ports again? Is my Pi broken?

Thanks for the help...

Do you mean dmesg gives a list of overcurrent warning?
