I purchased a rpi2 last month and used it only a couple times with the same setup everytime (same sdcard, same psu, same usb adapters plugged - wifi dongle and logitech wireless keyboard+mouse which always worked on both rpi 1 B and rpi 2 B until now.
A week ago I turned it on and somehow it isn't recognizing any usb devices I plug in.
Ever since it's been flashing red light once it boots. I know it's related to bad power supply, but I'm pretty sure power supply is good and I've tried others 2 psu which resulted in the same red flashing light on PWR led. I tried 4 different psu being three of them 5v/2a (oneplus one, nook hd and ipad) and one 5v/1A (apple).
Ethernet is working normally and I can SSH to rpi.
Also, I formatted sdcard changing from noobs with dual-boot to raspbian so I could have ssh always on.
When typing 'dmesg' I'm having this being flooded 4x/second:
I'm not sure but I think lsusb is reporting correctly:[ 195.381316] usb 1-1-port2: over-current change
