Hello,

I am having a problem getting USB to work on an ADM5120 based board  
(Edimax BR6104KP*) - although the USB hub is recognised on boot when  
I try to plug a device in I get a 'uhub0: device problem, disabling  
port 1' message. Unfortunately I am not quite sure where to start - I  
have attached a dmesg & debug output when a USB device is inserted  
below (with usbdebug & uhcidebug set to 5) and would be grateful for  
any pointers,

Regards, Paul
