micro2440SDK USB hub datasheet

Gentelmen, Does anyone know where to find the datasheet for USB hub
controller?
Thanks.

Think it is part of the ARM chip.  I don't see any separate USB host
controller on the schematic and the config_mini2440_n35 file for the 64M
factory distro says:

CONFIG_USB_OHCI_HCD=y (not sure if this is generic or not)

Have you got a datasheet for the S3C2440?

Good luck!

Hi Davef,
The USB of "mini" and "micro" schematics are different. Micro2440SDK board
is equipped with 4 port USB hub. The reason I am putting this message up is
that I was not able to find any info about hub controller.

OK.  Don't see any reference to a USB hub controller on the micro22440
schematics.  Could you read the part number off the IC?  The makers symbol
would help narrow the search down, if you can't read the part number.

@davef
I think the hub is on the base board, not the micro2440 board and i don't
think there are circuits for the base board...

Thanks,
Errol

The micro2440-SDK schematics are also available:

There is no info on this datasheet what IC is used.
Please check !

I observed that the U3 in page 4 of the file
"micro2440-sdk_schematic_20090530" of the site
http://www.friendlyarm.net/dl.php?file=micro2440_schematic.zip is the 
AU9254A21-HAS-NP / SLO692 / 07497.
