ath9k -> bogus usb xfer on at91

Hi,

While porting an internal BSP (a design based on a at91sam9g20 SoC)
from 3.10 to 3.14, I got flooded with messages like:

[PATCH] usb: chipidea: udc: avoid gadget driver insertion in host mode

From: Abbas Raza <Abbas_Raza@...>

When gadget driver is inserted and OTG is in host mode, interrupts
occur which are not handled by chipidea driver causing following
problem. To avoid this problem, don't allow insertion of gadget
driver in host mode.

[PATCH] drivers: phy: exynos-usb2: add support for Exynos 3250

This patch adds support for Exynos3250 SoC to Exynos2USB PHY driver.
Although Exynos3250 has only one device phy interface, the register
layout and all operations that are required to get it enabled are almost
same as on Exynos4x12. The only different is one more register
(REFCLKSEL) which need to be set.

[PATCH 7/7] fsl/otg: Resolve OTG crash issue with another host

Resolves kernel crash issue when a USB flash drive is inserted
into USB1 port with USB2 port configured as otg. Removing
"else" block so that the controller coming up in "non-otg" mode
doesn't return -ENODEV. Returning "ENODEV" results in platform
framework unbinding platform-drv from controller resulting in
kernel crash later in hub driver

This change makes two more one-time per HCD allocations to be done

some bits of space in coherent atomic DMA pool, which is 256KB by
default on ARM platform.

[PATCH] USB: EHCI: don't allocate hardware periodic table atomically by default

ehci_mem_init() is executed one time during ehci_init() and by default
all memory allocations but ehci->periodic are done not atomically,
GFP_KERNEL is passed as flags parameter.

Do similar allocation for ehci->periodic and free some space in
coherent atomic DMA pool by default.

Problem with Mobile Broadband on ubuntu

Hello,
    I am on Ubuntu 12.04, and am trying to install a USB dongle with a
3-g simcard. I have D-link 156 dongle.

    I do the following 2:
- dpkg -i <file>.deb
- usb_modeswitch ...

after this, i am not able to locate the driver in Network Manager.

If i do dmesg, it says:
usbserial_generic 1-1.3:1.5: Tell linux-usb@... to add
your device to a proper driver.

hence emailing you.

Thanks,
Arun
