Subject: [BUG] usb/at91: usb hub does not work
Date: Thu, 11 Jun 2015 11:42:27 +0200 [thread overview]
Message-ID: <55795803.30302@aksignal.cz> (raw)
Hi all,
I discovered some bug when I change kernel from 3.18.13 to 3.18.14. I have board with usb hub CY7C65632 on it.
In .13 it works fine but in .14 it repeats this message:
[ 19.170000] usb 2-3: new full-speed USB device number 56 using at91_ohci
and devices connected to usb through hub doesn't appear at all.
Here is dmesg | grep usb of .14:

Any idea?
