+General Description:
+This module offers additional functionality for host side drivers based on
+libusb or libusb-win32. It includes a function to find and open a device
+based on numeric IDs and textual description. It also includes a function to
+obtain textual descriptions from a device.
+
+To use this functionality, simply copy opendevice.c and opendevice.h into your
+project and add them to your Makefile. You may modify and redistribute these
+files according to the GNU General Public License (GPL) version 2 or 3.

+/* This function gets a string descriptor from the device. 'index' is the
+ * string descriptor index. The string is returned in ISO Latin 1 encoding in
+ * 'buf' and it is terminated with a 0-character. The buffer size must be
+ * passed in 'buflen' to prevent buffer overflows. A libusb device handle
+ * must be given in 'dev'.
+ * Returns: The length of the string (excluding the terminating 0) or
+ * a negative number in case of an error. If there was an error, use
+ * usb_strerror() to obtain the error message.

+int usbOpenDevice(usb_dev_handle **device, int vendorID, char *vendorNamePattern, int productID, char *productNamePattern, char *serialNamePattern, FILE *printMatchingDevicesFp, FILE *warningsFp);
+/* This function iterates over all devices on all USB busses and searches for
+ * a device. Matching is done first by means of Vendor- and Product-ID (passed
+ * in 'vendorID' and 'productID'. An ID of 0 matches any numeric ID (wildcard).
+ * When a device matches by its IDs, matching by names is performed. Name
+ * matching can be done on textual vendor name ('vendorNamePattern'), product
+ * name ('productNamePattern') and serial number ('serialNamePattern'). A
+ * device matches only if all non-null pattern match. If you don't care about
+ * a string, pass NULL for the pattern. Patterns are Unix shell style pattern:
+ * '*' stands for 0 or more characters, '?' for one single character, a list
+ * of characters in square brackets for a single character from the list
+ * (dashes are allowed to specify a range) and if the lis of characters begins
+ * with a caret ('^'), it matches one character which is NOT in the list.
+ * Other parameters to the function: If 'warningsFp' is not NULL, warning
+ * messages are printed to this file descriptor with fprintf(). If
+ * 'printMatchingDevicesFp' is not NULL, no device is opened but matching
+ * devices are printed to the given file descriptor with fprintf().
+ * If a device is opened, the resulting USB handle is stored in '*device'. A
+ * pointer to a "usb_dev_handle *" type variable must be passed here.
+ * Returns: 0 on success, an error code (see defines below) on failure.
