Runing MFGTool with kernel 3.14 hangs with windows driver error

Im working on custom SabreSD board and I compiled U-boot 2015 and Kernel 3.14 for MFG firmware. When I run the tool it downloads u-boot, kernel, rootfs and dtb then jumps to OS. I see it boots u-boot and kernel in uart console, and then device disconnects from Windows 7 PC and it should connect again but Windows pops up error: "Device driver software was not successfully installed", and MFG Tool hangs with "No device Connected"...


Last UART log from kernel is:

g_mass_storage gadget: Mass Storage Gadget, version: 2009/09/11

g_mass_storage gadget: g_mass_storage ready

Freeing unused kernel memory: 432K (c0bbf000 - c0c2b000)

Starting UTP

uuc 0.5 [built Dec  3 2015 08:26:46]

UTP: Waiting for device to appear

UTP: file/device node /dev/utp already exists

cpu_id is 0


Is there something in kernel config I should tweak for windows to get this device? I have it working with older kernel 3.0.
