The check was added in 77547d5313ea916d2fb64ca5a8812734e9b50f92, but it doesn't work as expected. Because the second part is wrapped in Optional(), it would silently "succeed" when the lowercase digits were in the second part: >>> from parse_hwdb import * >>> g = 'v' + upperhex_word(4) + Optional('p' + upperhex_word(4)) >>> g.parseString('v04D8pE11C*') (['v', '04D8', 'p', 'E11C'], {}) >>> g.parseString('v04D8pe11c*') (['v', '04D8'], {}) The following matches are OK: usb:v0627p0001:*QEMU USB Keyboard* usb:v0627p0001:* usb:v0627p0001* usb:v0627* (cherry picked from commit 1a37237e2ffe6dfe142224a9d9e8b24135e93244)
