USB ports on keyboards

[Zamorph]

Do the usb ports on keyboards have any problems?  Some keyboards sport usb 2.0, do they have any input lag?  Thanks

Input lag comes from many other sources and many other components; than the ports themselves.

Ah gotchya, if I used double usb ports, I would probably have my Headset and either a mouse/ipod in the second one, think it could handle it?

There won't be lag, but it would definitely affect the bandwidth. I did witness reduce in pulling rate when my mouse is plug into a hub sharing bandwidth with other device. No biggy though, for the most part.

Ahhh I thought that would happen.

I actually have a mouse receiver and a Droid Z (tmobile G2 in the US) connected to my backlit keyboard, w/o any problem.

That said it depends on the mainboard and its age.

Lulz.  Wrong again.  Especially unforgivable after trolling the "My IBM doesn't work on PS/2" thread.

USB is a regulated 5.0V and amperage.  Only real exception is laptops.  They suck at following specifications.

Is it 5 per USB? I just looked up my head set and it needs 3.0 V, 2.2 K ohm

You should read "The Fox and the Grapes" you can learn a lot about yourself.

You should also try to speak about something you tried.


Unlike you, most of the modern motherboards are vastly tolerant about the current they provide trough USB, sometimes you can drain even 2 A (which is 4x what the specs recommends).
