Hi,
my test steps:
smsc9514 is activated in u-boot first
=> 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

2: Hub,  USB Revision 2.0
 - Class: Hub
 - PacketSize: 64  Configurations: 1
 - Vendor: 0x0424  Product 0x9514 Version 2.0

   - Interfaces: 1 Self Powered Remote Wakeup 2mA
     Interface: 0
     - Alternate Setting 0, Endpoints: 1
     - Class Hub
     - Endpoint 1 In Interrupt MaxPacket 1 Interval 12ms
     - Endpoint 1 In Interrupt MaxPacket 1 Interval 12ms

3: Vendor specific,  USB Revision 2.0
 - Class: Vendor specific
 - PacketSize: 64  Configurations: 1
 - Vendor: 0x0424  Product 0xec00 Version 2.0
   Configuration: 1
   - Interfaces: 1 Self Powered Remote Wakeup 2mA
     Interface: 0

     - Class Vendor specific
     - Endpoint 1 In Bulk MaxPacket 512
     - Endpoint 2 Out Bulk MaxPacket 512
     - Endpoint 3 In Interrupt MaxPacket 16 Interval 4ms

then booting kernel and I get such related debug messages:

Any ideas?
