Hi All,
In board, we have 2 USB controllers and the first port with USB Mass storage is detected without any problem and 2nd Controller with USB Mass storage is not detected properly. Sometimes it is detecting and sometimes, it is not detecting.
In U-Boot version U-Boot 2011.12, When detect the USB, got the below errors:
U-Boot>> usb start (Re)start USB... USB: Active port: 1 Register 10011 NbrPorts 1 USB EHCI 1.00 *scanning bus for devices... port(0) reset error* *port(0) reset error* *port(0) reset error* *port(0) reset error* *port(0) reset error* *cannot reset port 1!?* 1 USB Device(s) found scanning bus for storage devices... 0 Storage Device(s) found
When USB works, the output is:
U-Boot>> usb start (Re)start USB... USB: Active port: 1 Register 10011 NbrPorts 1 USB EHCI 1.00 scanning bus for devices... 2 USB Device(s) found scanning bus for storage devices... 1 Storage Device(s) found U-Boot>> usb info 1: Hub, USB Revision 2.0 - u-boot EHCI Host Controller - Class: Hub - PacketSize: 64 Configurations: 1 - Vendor: 0x0000 Product 0x0000 Version 1.0 Configuration: 1 - Interfaces: 1 Self Powered 0mA Interface: 0 - Alternate Setting 0, Endpoints: 1 - Class Hub - Endpoint 1 In Interrupt MaxPacket 8 Interval 255ms

Please help on this.
When enable the debug printf(), then the error messages is:

In 2nd Controller, USB Mass storage detection is inconsistent. Need to test this in U-Boot version U-Boot 2011.12.
