Re: [LAU] jdelay - measured latency of a usb interface

Indeed they do alls have the same latency introduced from the usb-protocol added to their specific latency, but that specific latency still depends on the actual hardware and the driver. And yes, there are different usb-audio drivers in the linux kernel, just search for *usx2y* for example. And the hardware latency is determined by the converters and the processing chip, just like with any other sound device, be it pci, pcmcia or firewire based... Have fun and excuse my nitpicking, Arnold
