Hello Marek,
I checked with mainline uboot as well. The issue is now clearer. Here are some info:
1. The board uses SMARC module 2. Whenever reboot command is given the usb is detected correctly. 3. When i give a hard reset, the following log is seen.
U-Boot > usb start (Re)start USB... USB0: USB EHCI 1.00 scanning bus 0 for devices... EHCI timed out on TD - token=0x80008c80 1 USB Device(s) found scanning usb for storage devices... 0 Storage Device(s) found
4. Again i boot and do a soft reboot, the same USB is detected.
This is definitely something related to power.
This is something mysterious for me. Anybody has any clue please let me know.
Regards, Manju

Hello Marek,
Hi
If the USB is detected successfully, then below are the logs.
My understanding is that you use u-boot 2013.04, which is about three years old now ? If you observe some problem, please try with mainline first and report back.
