I have some problems with usb driver porting of mpc834x..
 

# Environments
kernel-2.4.23
MPC8347(MPH module) <--> USB3300(ULPI) <--> USB disk module
USB2.0, EHCI

question1) 'usb_control/bulk_msg: timeout'... what is it ? what is happened?
question2) 'usb.c: USB device not accepting new address=3 (error=-110)'
Do you know that error code list of standard? (ex. error=-110)
question3) What is MPH/DR module? These are Host mode?

check point 1) Currently D+/D- pattern is directly connected between USB3300 phy and the usb device.
