I have the exact same problem!!
Many users reports that it can be solved by deleting the kext inside IOUSBHost kext. But I can't rebuild the USB device kernel cache and so I have always the same error even when deleting the kext.
Please help if anyone can.
My hardware is the one in my profile

I made some researches and it seems to be a well known error.
I have a P35 chipset, not X58 (that has a better solution for that error).
Please, could anyone tell us, how to rebuild the kernel cache for the external USB installer??
Because I wanted to try to boot deleting the kext but it still remains in the kernel cache and gives me the same error even if I delete it.
I tried booting without caches but without any luck as well.
Please help us!

I have the exact same issue and I have system specs written in my profile.
Please help.
I get this exact kernel panic and my computer restarts.
I cannot rebuild USB kernel cache as well.
Please help me if you can.

LOL! Agreed.
I'm not familiar with your board. There are options for two chipsets in the big list of solutions, though perhaps neither are yours?
If you just want to delete a kext and rebuild cache, try to boot to single-user mode (and run the fsck/mount commands it gives you) or the recovery partition (and run Utilities/Terminal). Then delete the kexts and touch S/L/E. The paths are different for single-user vs recovery (recovery has a prefix of /Volumes/YourDriveName), but something like:
Code:
rm -rf /System/Library/Extensions/foo.kext
touch /System/Library/ExtensionsThen either run "reboot" or choose reboot from the Apple menu.
Then on the next boot, his space bar and choose boot without caches.

Thank you for your answer!
I made several tries and I can confirm that IT WORKS!!!
I just applied DSDT fixes (mask 0x000000105B) that worked for X58 chipset on my configuration and it worked very well!
So I can confirm that the method used for X58 chipset is ok for P35 chipset as well!!
Thank you so much!

I figured out the setting Kenia and others are referring to and am pasting the original config and my config below.
It worked for me on an EP45-UD3P (old board!). No Kernel Panics on HPET or AppleUSBetc.
The link in the "Big List of Solutions" takes you to the beginning of a thread but the answer is currently at the top of Page 2 of where it links. "nothingmore" user's settings from 2 years ago don't match my clover (as of 8/30/2017) so I made the similar choices in the current Clover.
I have some extra settings that you might not need (I might not need them either but I haven't tested).
The critical setting for me was "Fix Darwin" as my other ones were ticked already... I didn't even see the "Add MCHC" choice until now and was able to boot without it (but I'm turning it on anyway). I don't have the New Way/Old Way option as you can see from my config. As promised, here is nothingmore's config and mine:
Two last notes: 1) I am using NullCPUPowerManagement kext and 2) I could temporarily boot my system past the KP without the Clover Unibeast USB stick by using the arrows to get to "Options" (there are two kinds of options, you just want "Options") on my Clover boot screen, selecting "ACPI patching", "DSDT fix mask", and deselecting "Fix HPET" then exiting that and selecting my startup drive for booting.
Good luck!
