A wake-up system for universal serial bus of computer wireless input device comprises a USB 10 connected to computer main body 1, and a receiver 8 connected to the USB 10, wherein a wireless keyboard 2 and a wireless mouse 3 transmit infrared or RF signals to be received by the receiver 8 to control and operate the program executed by the computer main body 1. When the power management device of the computer system switches the computer and the USB 10 into suspension mode, the receiver 8 is set to switch between a suspension mode and an operating mode, and the average current (Iave) of the receiver 8 must be less than the limit average current (SUBIave) of USB 10 during suspension mode. When the computer is at suspension status and the user wants to use the computer again, the user can operate the wireless keyboard 2 or mouse 3 to transmit a continuous wake-up signal which can be received and detected by the receiver 8 during its operating mode to let the computer promptly quit the suspension status to resume its original status before suspension status.
