Gentelmen, Does anyone know where to find the datasheet for USB hub controller? Thanks.
micro2440SDK USB hub datasheet
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: http://www.friendlyarm.net/micro2440/micro2440-sdk_schematic_20090530.pdf Regards, Andreas
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.
