Devices like the "Microsoft Microsoft® 2.4GHz Transceiver v9.0 Mouse" contain
characters higher than 127. That ® is correctly stored in the hwdb and passed
into the search field during query, but the comparison fails.
Our search string is a const char *, trie_string() returns a const char * but
the current character is cast to uint8_t. This causes anything over 127 to
fail the match. Fix this, we're dealing with characters everywhere here after
all.
size_t p = 0;
if (node->prefix_off) {
- uint8_t c;
+ char c;
for (; (c = trie_string(hwdb, node->prefix_off)[p]); p++) {
if (IN_SET(c, '*', '?', '['))
