      USB: musb: omap2430: fix kernel panic on reboot · 19b9a83e
      由 Johan Hovold 提交于 
      Cancel idle timer in musb_platform_exit.

The idle timer could trigger after clock had been disabled leading to
kernel panic when MUSB_DEVCTL is accessed in musb_do_idle on 2.6.37.

The fault below is no longer triggered on 2.6.38-rc4 (clock is disabled
later, and only if compiled as a module, and the offending memory access
has moved) but the timer should be cancelled nonetheless.

      sierra: add new ID for Airprime/Sierra USB IP modem · e1dc5157
      由 Jon Thomas 提交于 
      I picked up a new Sierra usb 308 (At&t Shockwave) on 2/2011 and the vendor code
is 0x0f3d

Looking up vendor and product id's I see:

0f3d  Airprime, Incorporated
 0112  CDMA 1xEVDO PC Card, PC 5220

Sierra and Airprime are somehow related and I'm guessing the At&t usb 308 might
be have some common hardware with the AirPrime SL809x.

      USB: Reset USB 3.0 devices on (re)discovery · 637d11bf
      由 Luben Tuikov 提交于 
      If the device isn't reset, the XHCI HCD sends
SET ADDRESS to address 0 while the device is
already in Addressed state, and the request is
dropped on the floor as it is addressed to the
default address. This sequence of events, which this
patch fixes looks like this:

usb_reset_and_verify_device()
	hub_port_init()
		hub_set_address()
			SET_ADDRESS to 0 with 1
		usb_get_device_descriptor(udev, 8)
		usb_get_device_descriptor(udev, 18)
	descriptors_changed() --> goto re_enumerate:
		hub_port_logical_disconnect()
			kick_khubd()

And then:

hub_events()
	hub_port_connect_change()
		usb_disconnect()
			usb_disable_device()
		new device struct
		sets device state to Powered
		choose_address()
		hub_port_init() <-- no reset, but SET ADDRESS to 0 with 1, timeout!

The solution is to always reset the device in
hub_port_init() to put it in a known state.

      USB: Add quirk for Samsung Android phone modem · 72a012ce
      由 Maciej Szmigiero 提交于 
      My Galaxy Spica needs this quirk when in modem mode, otherwise
it causes endless USB bus resets and is unusable in this mode.

Unfortunately Samsung decided to reuse ID of its old CDMA phone SGH-I500
for the modem part.
That's why in addition to this patch the visor driver must be prevented
from binding to SPH-I500 ID, so ACM driver can do that.

      [USB]Add Samsung SGH-I500/Android modem ID switch to visor driver

Samsung decided to reuse USB ID of its old CDMA phone SGH-I500 for the
modem part of some of their Android phones. At least Galaxy Spica
is affected.

This modem needs ACM driver and does not work with visor driver which
binds the conflicting ID for SGH-I500.
Because SGH-I500 is pretty an old hardware its best to add switch to
visor
driver in cause somebody still wants to use that phone with Linux.

Note that this is needed only when using the Android phone as modem,
not in USB storage or ADB mode.
