Hi ,
I had ported usb3.0 xHCI driver code (not merged yet in the U-Boot : http://patchwork.ozlabs.org/patch/193477/ ) from U-Boot to Barebox. Using that I was able to detect the Controller and hub but not the usb storage devices.
So I thought porting usb3.0 xHCI driver code as is (not integrating in barebox usb driver framework) from U-Boot to barebox and also ported the Barebox's usb core and command code just to test whether original code works fine. But still code not able to detect any storage device device but controller and hub.
I get as shown below:
"usb_storage_probe:1237:Probing Storage Devices...... 0 Storage Device(s) found"
