I forgot to comment, I am configuring usbh2's portsc as on mx31lite:

.portsc = MXC_EHCI_MODE_ULPI | MXC_EHCI_UTMI_8BIT,

I defined and configured usbh2 pins:
        /* USBH2 */
        PA0_PF_USBH2_CLK,
        PA1_PF_USBH2_DIR,
        PA3_PF_USBH2_NXT,
        PA4_PF_USBH2_STP,
        PD22_AF_USBH2_DATA0,
        PD24_AF_USBH2_DATA1,
        PD23_AF_USBH2_DATA2,
        PD20_AF_USBH2_DATA3,
        PD19_AF_USBH2_DATA4,
        PD26_AF_USBH2_DATA5,
        PD21_AF_USBH2_DATA6,
        PA2_PF_USBH2_DATA7,
        PA24_AIN_SLDCD1_D0, /* EN_B */
        PA26_PF_PS, /* RES_B */

What you think could be this issue?

Thank you very much,
