Print job long startup time! (Solved)

I've upgraded a new PC, but encountered a problem of a long waiting time for a print job!

====================
Hardware:
PC
ASUS P7P55D (BIOS: 0501)
Intel i-5 750

Printer
HP LaserJet 1022
HP PhotoSmart 7450
Kyocera Mita FS-1010

Software:
OS
Windows 7 Home Premium

====================

1.When directly connect the printer to PC via the USB port on motherboard:

The following printer had this problem!
HP LaserJet 1022 (Laser) (Have to wait about 2 mins.)
Kyocera Mita FS-1010 (Laser) (Have some problem when adding the printer.)

The following don't have!
HP PhotoSmart 7450 (Ink)

2.But when I connected the HP LaserJet 1022 to the USB port of ASUS WL-520GU,
using ASUS WL-520GU to be the printer server. Printe waiting time lower to about 10~30sec or so.

3.I checked if there're some firmware or driver upgrade!
I upgraded the BIOS version of ASUS P7P55D from 0501 to 0915.
SOLVE the problem!!

BIOS version 0915 of ASUS P7P55D fixed some USB compatibility problems!
