After booting with the original OC configuration file and using gfx0 < igpu and pegp < gfx0, the problem of USB card appears. Is it in conflict with which patch.You've already booted OC successfully - what happened? Please post your config.plist with each request for help.
I think this is a USB problem. Are you using the correct USBPorts.kext for your iMac19,1?
@lydahai Sometimes when switching from CLOVER to OC (or OC to CLOVER), I have found it best to clear NVRAM.
