Hello,
I'm working on our new custom board with dm365 (based on evm kit) running linux-2.6.32 from the dvsdk. Unfortunately I'm facing some problems with usb. There is a 4 port usb hub on the board connected to the processor. When the board is powered and booting the kernel the detection of the hub almost always ends with timeout in hub_port_status function.

When I do a warm reboot (using reboot command) then the usb hub sometimes start to work properly and I'm able to connect another devices like hdd or card reader. The dmesg | egrep -i "usb|hub" is following then.

Can someone give me any advice how to solve this problem? I'm not sure if it is in hw (the connection differs from the evm: USB_ID is tied low (host mode), USB_VBUS is tied to 5V and USB_DM and DP are interconnected to the hub (SMSC 2514b). USB_DRV_VBUS is not used on our board) or there is some problem in the driver.
with best regards
Jan
