cydonia,
the answer to your initial question is "no"... you cant get drivers from a USB device while installing windows. it must be from a floppy disk OR you can burn your own custom XP disc with your drivers integrated.
it sounds like you have other more important issues right now though. it sounds like you cant boot from CDROM. I would give that priority right now... otherwise you will never install XP.
Do you happen to know what BIOS version youre running? The latest final released BIOS is 1017. There is also a beta of 1018.001 available but you probably dont want that.
There is a
manual available for your motherboard if you dont have it.
If I were you, I would disconnect all SATA cables from your motherboard. Hook a single IDE cable from the motherboard (PRI_IDE closest to memory slot) directly to the CDROM drive. MAKE SURE the jumper on the CDROM is set to master. Then turn the computer back on and see if you can boot from CD.
