Need help fixing USB on HP xw4600 workstation

[rahulk70]

Hi everyone,

I followed the high sierra beta installation guide here and installed it on my build.

Mobo: HP XW4600 Intel 441449-001Motherboard (intel x38)
GPU :Gigabyte Nvidia GT240
CPU: Intel Core 2 Quad Q9650

I was unable to get the installer to boot with the old version of clover 4048 but since r4200 everything seems to boot fine now. Though I had to disable nvidia to avoid black screen.Also I applied the USB patches in the clover configurator and got past the "still waiting for root issue".

I've two HDDs one running Sierra (fully working and primary OS for all activities) and second one that I installed for high sierra. Sierra works only with Enoch r2989 bootloader. Clover always gives me nvidia kernel panic.

I formatted in my second HDD in 2 GUID partitions i.e Macintosh HD and Recovery HD (a 20 gigs Recovery HD helped to use network reinstall incase I didn't have my USB). The initial installation (with 17a291m build) went fine and I was able to boot but only with nv_disable flag else the black screen issue comes up. Here USB is working fine while booting with USB installer(with clover).
Post installation since the main bootloader is Enoch r2989 on sierra so I'm forced to boot High sierra also with the same only with no USB support. Currently USB keyboard and mouse runs on PS2 port with adapter.

Story aside main issue, yesterday did a wipe again from recovery partition which booted to the internet recovery and did a fresh install again which was to the latest GM build. Now on booting graphics worked OOB only issue was again the USB. Images attached below. USBInject.kext also seems to not work with enoch only in clover. Any ideas to fix?

Thanks in advance. Sorry for the long post, just wanted to make everything clear to avoid any confusions. I've attached pics from old and new build.
