EHCI problem at rev C3, HW error ?


A few days ago I bought a BB rev C3. I have a problem with USB. When I
put any USB device gets the message "hub 1-0:1.0: unable to enumerate
USB device on port 2. Besides board does not pass a validation test. I
use a external power adaptor 5V/2A ans working USB 2.0 Hub. Should I
request an RMA for this ?

It depends. What sort of device are you trying to connect? The EHCI port is HS only and cannot support LS devices, such as keyboards and mice, without a hub.
