How fast can i get data from a USB device?

I realize that this depends on a lot of factors, but if anyone has a ballpark idea, it would be helpful.  I'm considering building a peripheral device and interfacing it with a computer via usb(which will admittedly take a bunch of research on its own), but i am curious how quickly data can get into a program from a USB port.  Like, can it go as low as nanoseconds?  Or is it as slow as milliseconds?

And i don't mean the speed of the data along the cable, i can just look up the speeds of the latest USB standard.  I mean, how long it takes a program that executes some "get data from usb port" function to actually retrieve that data and be available for use in the program.

How fast can i get money from a stupid goyim?

I realize that this depends on a lot of factors, but if anyone has a ballpark idea, it would be helpful.  I'm considering realizing a pyramid scheme

Why the unhelpfulness?

No one EVER helped us. Why should we help you, cocksucker? Just die in pain, filth.

``us"? You weren't there, bitter Jew.

Wait, you are talking about the 6 billion that died that day, right?

Be naic.

Come on... why wont you download a benchmark program and see for yourself?

Later post a thread on reddit|stackoverflow about it and link it to /prog/, then go to /b/ and fap to some random shit.

Do you mean speed or latency? Full-speed USB has a minimum latency of 1ms, high-speed has a minimum latency of 0.125ms IIRC. Don't know about superspeed, don't care about low speed.

From experience, hitting that 1ms is achievable, but requires careful design on both the host and device end.
