As suggested by Stian Skjelstad in a comment in:
http://openocd.zylin.com/#/c/2044/
if the USB product string cannot be read, provide a debug message so
users might get aware of a potential permission problem when looking
at the debug output.
Fix style bug found by Jenkins.

The existing CMSIS-DAP driver matches the USB VID/PID against 0x3eb
(Atmel VID) and 0x2111 (Atmel EDBG embedded CMSIS-DAP debugger), and
then bumps the packet size from its default of 64 to 512. However, it
turned out that *all* Atmel-provided CMSIS-DAP devices (EDBG with PID
0x2111; JTAGICE3 with firmware version 3.x, PID 0x2140; new Atmel-ICE
[successor of JTAGICE3], PID 0x2141) require a 512-byte packet size.
Obviously, all run the same USB implementation inside their custom
microcontroller. Thus, it seems best to simply assume that *all*
Atmel CMSIS-DAP devices use this packet size, and don't check the PID
at all.

In the CMSIS-DAP driver, if nothing has been specified by the user, an
attempt is made to find the first device with the (mandatory)
substring "CMSIS-DAP" in any USB device's product string. However,
while (usually) all devices can be traversed, devices the user does
not have permission for cannot be read the product string from,
resulting in a NULL pointer. Trying to find the substring "CMSIS-DAP"
causes a segementation fault then.

Rename the argument variable 'wait' to 'delay', as 'wait'
conflicts with an API function declared in system header
/usr/include/sys/wait.h on Mac OS X.

The current OpenOCD implementation requires CMSIS-DAP adapter USB
VID:PID values to either be hard-coded in the source or manually
supplied by the user's configuration files. The CMSIS-DAP
specification stipulates that all compliant adapters should have
"CMSIS-DAP" in the product string. This should obviate the need
for hard-coding.
This patch was previously submitted as changes 1882, 1883, and 1886
but amendments failed to be registered by the server. The
functionality was changed from 1886 in response to comments so that
user-supplied VID:PID values overrided the CMSIS-DAP auto-detect.

This is based on work from:
https://github.com/TheShed/OpenOCD-CMSIS-DAP/tree/cmsis-dap
Main changes include moving over to using HIDAPI rather than libusb-1.0
and cleaning up to merge into master. Support for reset using srst has
also been added.
It has been tested on all the mbed boards as well as the Freedom board
from Freescale. These boards only implement SWD mode, however JTAG mode
has been tested with a Keil ULINK2 and a stm32 target - but requires a lot
more work.
