Certain USB devices, such as the Nokia X6 mobile phone, don't expose any
endpoint descriptors on some of their interfaces. If the ACM driver is forced
to probe all interfaces on a device the a NULL pointer dereference will occur
when the ACM driver attempts to use the endpoint of the alternative settings.
One way to get the ACM driver to probe all the interfaces is by using the
/sys/bus/usb/drivers/cdc_acm/new_id interface.
This patch checks that the endpoint pointer for the current alternate settings
is non-NULL before using it.

The command endpoint is either a bulk or interrupt endpoint, but using
the wrong type of transfer causes an error if CONFIG_USB_DEBUG is
enabled after commit f661c6f8c6, which
checks for this mismatch.
Detect which type of endpoint it is and use a bulk/int URB as
appropriate. There are other function calls specifying a bulk pipe,
but usb_clear_halt doesn't use the pipe type (only the endpoint) and
usb_bulk_msg auto-detects interrupt transfers.

S60 phones from Nokia and Samsung expose two ACM channels. The first is a modem
with a standard AT-command interface, which is picked up correctly by CDC-ACM.
The second ACM port is marked as having a vendor-specific protocol. This means
that the ACM driver will not claim the second channel by default.
This adds support for the second ACM channel for the following devices:
Nokia E63
Nokia E75
Nokia 6760 Slide
Nokia E52
Nokia E55

When using the remove sysfs file, the device configuration is set to -1
(unconfigured). This eventually unbind drivers with the bandwidth_mutex
held. Some drivers may call functions that hold said mutex, like
usb_reset_device. This is the case for rtl8187, for example. This will
lead to the same process holding the mutex twice, which deadlocks.
Besides, according to Alan Stern:
"The deadlock problem probably could be handled somehow, but there's a
separate issue: Until the usb_disable_device call finishes unbinding
the drivers, the drivers are free to continue using their allocated
bandwidth. We musn't change the bandwidth allocations until after the
unbinding is done. So this patch is indeed necessary."
Unbinding the driver before holding the bandwidth_mutex solves the
problem. If any operation after that fails, drivers are not bound again.
But that would be a problem anyway that the user may solve resetting the
device configuration to one that works, just like he would need to do in
most other failure cases.

Unfortunately some of the hardware PID belonging to auto-install CDROM
(AICD) of Novatel modems found their way into the option module. This
causes the AICD to be treated as a modem in stead of a disk. Since the
modem ports do not appear until after the AICD is ejected, this
essentially disables the modem. After a couple of minutes the AICD
should auto-eject, but it is just too long a wait. The frequency of the
failure seems to depend on both the hardware and the linux distribution.
Here is a patch that fixes this up, and also adds a couple of new PID,
offering some explanations and removing some incomplete and unnecessary
comments.

This patch fixes a isoc transfer bug reported by Sander Eikelenboom.
When ep->skip is set, endpoint ring dequeue pointer should be updated
when processed every missed td. Although ring dequeue pointer will also
be updated when ep->skip is clear, leave it intact during missed tds
processing may cause two issues:
1). If the very next valid transfer following missed tds is a short
transfer, its actual_length will be miscalculated;
2). If there are too many missed tds during transfer, new inserted tds
may found the transfer ring full and urb enqueue fails.

The code to increment the TRB pointer has a slight ambiguity that could
lead to a bug on different compilers. The ANSI C specification does not
specify the precedence of the assignment operator over the postfix
operator. gcc 4.4 produced the correct code (increment the pointer and
assign the value), but a MIPS compiler that one of John's clients used
assigned the old (unincremented) value.
Remove the unnecessary assignment to make all compilers produce the
correct assembly.

The ISP1760 has some timing requirements where it has to delay a short
period after a write to a register has started. However, this delay is
from the time the write hits the USB chip (the ISP1760), not from the
time where the processor started processing the write. So on a quick
enough processor, it is sometimes possible for the write to not hit the
device before we start delaying, and we then violate the part's timing
requirements, so things stop working.
To avoid all this, insert a write barrier after the register write and
before the timing delay/register read so we can guarantee we only start
counting time after the write has hit the device.
