Subject: 2.6.21-rc4 fails to start USB HCD NEC 720101 with MPC8349EMDS
Date: Tue, 20 Mar 2007 09:17:34 +0100 [thread overview]
Message-ID: <45FF989E.4090106@ge.com> (raw)
Hello,
I have an MPC8349EMDS board with an 2.6.21-rc4 kernel and u-boot 1.2.0.
I use the dts file from the kernel sources.
I've plugged a PCI board with a NEC 720101
(http://www.necel.com/usb/en/product/upd720101.html).
This chip is a USB Host Controller with 1 EHCI if and 2 OHCI if.
It looks like the kernel sees the USB if, but it fails to start it:

Could someone help me to understand these messages?
