Hi,

on my Bananapis, in kernel 4.6 USB does not work. Kernel configuration
is USB-wise identical to 4.5 (grepped for differences in (hci|usb)),
and in 4.6 there is not even /dev/bus/usb.

Here is the log excerpt from a 4.5 kernel coming up:

In kernel 4.6, the message "ohci-platform: OHCI generic platform
driver" is the last one, and "ehci-platform 1c14000.usb: EHCI Host
Controller" is the first one that is missing.

Is this already a known issue? Or, does a 4.6 kernel need to be
configured differently if you want USB?

Greetings
Marc

Hint, include linux-usb@vger in usb-specific questions...

Are you sure you configured in the correct host controller that you
want?  Have you done a diff of your .config files to see what you
changed?  How did you create your 4.6 config?

thanks,
