I've tried "usbd.irx" & "usbhdfsd.irx" from 03\11\2018 FMCB\FHDB installer with few FMV (e.g Tomb Raider II, Colin McRae Rally 2.0, Legacy of Kain - Soul Reaver). It seems that everything should be fine (there ware no cracking sound or stuttering). If anybody else want to make a test, I've upload these drivers with icon for PS2 MC Browser. After unpacking, copy POPSTARTER folder on the root of a MC. Thanks @sp193 for a suggestion. EDIT: Added USB drivers from 05/11/2018.
