Picozed FMC carrier USB not detected

Hi,

I am using Picozed SoM, Picozed FMC carrier card Gen2 for my testing. I am using pre-built images developed by Avnet for 2015.4 version and booting the PS. By default, the scheme of carrier board says that USB is connected in HOST mode. When I am connecting a pendrive on the USB connector, it is showing the following messages.

root@pz_7030_2015_4:~# usb 1-1: new high-speed USB device number 6 using ci_hdrc
usb 1-1: device descriptor read/64, error -71
usb 1-1: device descriptor read/64, error -71
usb 1-1: new high-speed USB device number 7 using ci_hdrc

usb 1-1: new high-speed USB device number 9 using ci_hdrc
usb 1-1: device not accepting address 9, error -71
usb usb1-port1: unable to enumerate USB device

When I do lsusb, it shows this even if no USB is connected

Is there any change needed to be done in pre-built device tree or any other file? Kindly help.
