Add support for opening a specific device
Allow filtration and matching of specified Device ID, Product ID, Serial Number Fix an issue in listKeyboards (hidapi) with an out of bounds search when using serial number Fix possible null reference problem in listKeyboards (hidapi) that caused rare segfaults when traversing the device enumeration in increments of two Fix handling of output of listKeyboards (hidapi) where it was incrementing the dev list pointer, then accessing the node to look for device serial number (potential security risk) Fix handling of serial number output of listKeyboards (hidapi) to handle wchar_t instead of outputting the memory address Fix issue in listKeyboards (libusb) failure to finish cleaning up USB contexts, leading to a segfault if calling a separate function after listing keyboards. Fix issue in close (libusb) segfaulting if m_hidHandle was null, so added a check. Modify listKeyboards to provide a vector of DeviceInfo objects that can be used by calling applications instead of outputting to stdout directly. Implement a struct to hold information regarding device information and ability for a library caller to query this information to make decisions about the currently targeted device.
