I am looking at the usb/host/ehci-mxc.c file and I see that the write to the portsc USB register is currently only done for MX31:
#ifdef CONFIG_MX31 setbits_le32(&ehci->control, USB_EN);
__raw_writel(CONFIG_MXC_USB_PORTSC, &ehci->portsc); #endif
I think you need to allow the portsc register write on MX25 too (and maybe for all i.MX devices).
In Linux we have: .portsc = MXC_EHCI_MODE_SERIAL for MX25PDK
,where #define MXC_EHCI_MODE_SERIAL (3 << 30)
