The change [1] guarantees that the value pointed by 'prescaler'
gets always set, even when the adapter does not support the
specific mode requested (e.g. sync), or during trace disabling.
This works fine with the code in armv7m_trace_tpiu_config(), but
requires all the parameters to be valid also to disable the trace
(with 'enable==false'), otherwise returns error on incorrect
parameters or even causes segmentation fault if pointers
'trace_freq' or 'prescaler' are NULL.
Another problem in stlink_config_trace(), not linked with [1], is
caused by a tentative to change the settings on an already enabled
trace; the trace is disabled before the new parameters are fully
validated and in case of invalid parameters the trace is not
re-enabled.
It would be more logical to first check all the parameters, then
disable the trace, change the settings and re-enable the trace.
Practically revert [1] by checking 'enable==false' at function
entry, then disable trace and exit without any further check on
the other parameters.
For the case 'enable==true', validate all the function parameters
then disable the trace, update the trace settings and re-enable
the trace.
Modify the caller armv7m_trace_tpiu_config() to initialize the
variable 'prescaler' to a safe value to avoid the issue targeted
by [1].

b) TPIU_ACPR is set by armv7m_trace_tpiu_config()
target_write_u32(target, TPIU_ACPR, Prescaler-1), so
TPIU_ACPR = Prescaler-1
Replacing TPIU_ACPR in a), we get:
SWO_baudrate = TRACECLKIN/Prescaler, so
c) Prescaler = TRACECLKIN/SWO_baudrate
The Prescaler calculated by calculate_swo_prescaler() is greater by 1:
Prescaler = TRACECLKIN/SWO_baudrate + 1
The second problem is that even in situations when
an exact baudrate match is possible,
the resulting TRACECLKIN/Prescaler already has a 3% deviation.
For example, TRACECLKIN=88000000, SWO_baudrate=500000,
calculate_swo_prescaler will return Prescaler=171.
The correct value should be Prescaler=176 (TPIU_ACPR=175).

The adapter NXP LPC-Link2 is a USB composite device that provides
five interfaces; among three of them that are of HID class, only
one is cmsis-dap.
Accordingly to ticket 255, OpenOCD code is not opening the right
HID interface; then it fails to communicate with the cmsis-dap
while checking the adapter's info.
Unfortunately, hidapi does not provide any support for reading the
string descriptor of the interface, otherwise it would have been
trivial to look for the right cmsis-dap interface.
In fact the cmsis-dap specification reports:
The CMSIS-DAP Firmware can be also part of a USB composite
device. If this case, the HID Interface String must
contain the sub-string CMSIS-DAP.
This requirement is satisfied by the USB device descriptor of the
LPC-Link2 reported below, but cannot be used.
Add a quirk to let OpenOCD only accept interface number zero on a
LPC-Link2 device.

The code in cmsis_dap_usb_open() already searches for the right
HID device that corresponds to the adapter. By calling hid_open()
it asks hidapi to re-search the adapter again based on the VID:PID
and the serial string of the adapter it has just found!
Apart from being a run-time overhead, this has an additional
drawback; there are USB adapters built as composite USB devices
that, beside the cmsis-dap HID interface, have other HID
interfaces for other purposes.
A typical example is the NXP LPC-Link2, that over the 5 interfaces
0) cmsis-dap (HID)
1) VCOM-CDC
2) VCOM-CDC
3) LPCSIO (HID)
4) LPC-LINK2 DATA PORT (HID)
has 3 of them of HID class.
The code in cmsis_dap_usb_open() could select the right interface
but then cannot propagate this information to hid_open().
Replace the call to hid_open() with hid_open_path(), passing as
parameter the "unique" path of the HID device already found.
Checking in hidapi source code, the implementation of hid_open()
consists in enumerating the HID devices, scan for the first one
matching VID:PID and serial number, and opening it by calling
hid_open_path(). This analysis highlights that using directly
hid_open_path() should not introduce any regression.
While applying these changes, move hid_init() before enumerating
the HID devices. This has no real consequences because the HID API
is marked as optional but, logically, it should be called before
any other HID API.

The function perror() sends the output to stderr, but OpenOCD
cannot intercept such output to send it to the log.
Replace all occurrences of perror() with LOG_ERROR(), but keeping
the same output format of perror().
The replacement is done automatically through:
sed -i 's/perror("\([^":]*\)[: ]*")/LOG_ERROR("\1: %s", strerror(errno))/' src/jtag/drivers/*.c
