Topic: Add USB to DLINK DSL2640B Problem

Hi,

I try to add an usb port to this router based on BCM6328, the hardware part is missing ( but printed on the board ).

I've edited the file board_bcm963xx.c to add usb support for my board and added usb packages in menuconfig.
The usb hub is detected on boot, so I think the software part is ok.

In one case, when I plug an usb key ( or a self powered usb hard disk ), nothing is detected, led on usb key is off, but no error messages.
If I invert D+ and D-, I have this messages on boot :
bcm63xx_ehci bcm63xx_ehci.0: port 1 reset error -145 ( 10 times )
The led on usb key is on, but nothing is detected.

I tried to add 22ohm resistor in serial, 15Kohm pull down, even diode ( It seems there are diodes on the board , see picture ).

I do not know what is the problem, can someone help me ?
