- * must be given in 'dev'.

- 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.
