USB device latency?

Ive been doing A+ new computer hardware course and they basically say that all USB device got poor latency...
I got a musical keyboard here and funny thing it is 92 mili seconds latency by default when i connect it to Reason, see the pic:
But if i increase sample rate from 44,100 up to 192000 latency falls down to 21 miliseconds! Which by the way doesnt sound like 21 at all more like 80 ms.

I have no ASIO hardware on my Asus mother board for some reason. What can i do to lower latency?
For those who dont know - latency here is all about how long it takes for input from keyboard to sound different synthesizers in Reason.
My course tought me that fire wire conections have low latency, i wonder if they make firewire keyboards...

I'd be surprised if the problem is inherent to USB itself. I'd expect it to be caused by the device itself, the driver or the application software.

The way i see it there can only be one solution from these 3:
I need a
new keyboard new sound card or new driver / up grade reason

You'll need to understand the problem first before you start focusing on the solution. At this point, I take it you don't know exactly what the problem is.

Hahaha, good one, congrats I didn't think you'd solve it this quickly, but all the better!

Glad you got it solved, midi latency is a real bummer.
Just a note, I use a firewire audio interface and using it with my old system(state of the art circa 2002), I could not achieve acceptable latency regardless of driver or buffer settings. Thus I could not effectively use my vdrum kit or keyboard with my DAW in real time. I recently built a nice fast i5 rig and the hardware upgrade has allowed me to achieve virtually no latency, or at least existing latency is negligible. So a PC upgrade can make all the difference with midi latency.
