USB: ti_usb_3410_502: Fix ID table size

2016-10-26T15:15:42+00:00

Commit 35a2fbc941ac ("USB: serial: ti_usb_3410_5052: new device id for
Abbot strip port cable") failed to update the size of the
ti_id_table_3410 array.  This doesn't need to be fixed upstream
following commit d7ece6515e12 ("USB: ti_usb_3410_5052: remove
vendor/product module parameters") but should be fixed in stable
branches older than 3.12.

Backports of commit c9d09dc7ad10 ("USB: serial: ti_usb_3410_5052: add
Abbott strip port ID to combined table as well.") similarly failed to
update the size of the ti_id_table_combined array.

USB: fix invalid memory access in hub_activate()

2016-10-26T15:15:41+00:00

commit e50293ef9775c5f1cf3fcc093037dd6a8c5684ea upstream.

Commit 8520f38099cc ("USB: change hub initialization sleeps to
delayed_work") changed the hub_activate() routine to make part of it
run in a workqueue.  However, the commit failed to take a reference to
the usb_hub structure or to lock the hub interface while doing so.  As
a result, if a hub is plugged in and quickly unplugged before the work
routine can run, the routine will try to access memory that has been
deallocated.  Or, if the hub is unplugged while the routine is
running, the memory may be deallocated while it is in active use.

This patch fixes the problem by taking a reference to the usb_hub at
the start of hub_activate() and releasing it at the end (when the work
is finished), and by locking the hub interface while the work routine
is running.  It also adds a check at the start of the routine to see
if the hub has already been disconnected, in which nothing should be
done.

USB: ipaq.c: fix a timeout loop

2016-10-26T15:15:40+00:00

commit abdc9a3b4bac97add99e1d77dc6d28623afe682b upstream.

The code expects the loop to end with "retries" set to zero but, because
it is a post-op, it will end set to -1.  I have fixed this by moving the
decrement inside the loop.

usb: xhci: fix config fail of FS hub behind a HS hub with MTT

2016-10-26T15:15:35+00:00

commit 096b110a3dd3c868e4610937c80d2e3f3357c1a9 upstream.

if a full speed hub connects to a high speed hub which
supports MTT, the MTT field of its slot context will be set
to 1 when xHCI driver setups an xHCI virtual device in
xhci_setup_addressable_virt_dev(); once usb core fetch its
hub descriptor, and need to update the xHC's internal data
structures for the device, the HUB field of its slot context
will be set to 1 too, meanwhile MTT is also set before,
this will cause configure endpoint command fail, so in the
case, we should clear MTT to 0 for full speed hub according
to section 6.2.2

USB: option: add XS Stick W100-2 from 4G Systems

2016-10-26T15:15:32+00:00

commit 638148e20c7f8f6e95017fdc13bce8549a6925e0 upstream.

Thomas reports
"
4gsystems sells two total different LTE-surfsticks under the same name.
..
The newer version of XS Stick W100 is from "omega"
..
Under windows the driver switches to the same ID, and uses MI03\6 for
network and MI01\6 for modem.

There is also ttyUSB0, but it is not usable, at least not for at.

The device works well with qmi and ModemManager-NetworkManager.

USB: serial: option: add support for Novatel MiFi USB620L

2016-10-26T15:15:31+00:00

commit e07af133c3e2716db25e3e1e1d9f10c2088e9c1a upstream.

Also known as Verizon U620L.

The device is modeswitched from 1410:9020 to 1410:9022 by selecting the
4th USB configuration:

 $ sudo usb_modeswitch –v 0x1410 –p 0x9020 –u 4

This configuration provides a ECM interface as well as TTYs ('Enterprise
Mode' according to the U620 Linux integration guide).
