A "Rare" kernel panic?

My Computer supports only USB 1.1 EHCI and I'm trying to install macOS from a single 7GB USB stick. I also had more kernel panics but they were kernel extensions based. Now after fixing those kernel panics, I get kinda "Rare" error:

Maybe USB based Kernel Panic?

Hardware:

Intel Core 2 Duo E6850 (Conroe)

NVIDIA GeForce 9600 GT

7GB DDR2

ASUS P5KC GREEN Motherboard

Gigabyte Chassis Poseidon Silver case

​

Additional Information:

I'm trying to install El Capitan on a Legacy Machine.

I have tried USB mapping and it didn't help.

​

How can I fix that?
