Does someone know the power consumption of an USB backlit keyboard like the SteelSeries Apex? I'd like to connect it to a Keyboard/Mouse USB Switch that goes to PC by one USB 2.0 cable. The mouse I'm going to use is the SteelSeries Rival. Do I risk to "break" the USB port? I tried googling, but I haven't found any power consumption specification.
Thank you and sorry for bad english.
Edit 1: Do you think that with the 500 mA of the USB 2.0 I will be able to "feed" the keyboard and the mouse? In case, if I plug the USB 2.0 switch to an USB 3.0 port, is it able to draw 900 mA? (My USB hub is powered by just the PC's USB port)
Edit 2: The keyboard has a USB Y cable, but the producer doesn't say if it's necessary to the keyboard alimentation, or if it's eventually necessary to the keyboard's USB hub(it has a 2 port USB 2.0 hub)
Edit 3: I've finally found something about backlit keyboard power consumptions: http://www.ctielectronics.com/pdf/811675-Industrial-Keyboard-Backlight-Instensity-Adjustment.pdf "Power requirements for the backlit keyboard are less than 100mA @ 5VDC (typical), and all power required for backlighting is taken from the keyboard port of the Host PC": even if the one referred by the link is smaller than the one(so less LEDs) I specified I think that I should be able to feed keyboard and mouse with less than 500mA
Edit 4: I have received the objects, plugged them to the hub and they work correctly.
