Can I use the Nova-t USB2 or HVR-900 on a USB 1.x port?
No, the Nova-t USB2 REQUIRES a USB 2.0 port due to bandwidth requirements. As it’s a BDA-compatible device, the whole transport stream is sent to the PC, unfiltered (rather than single channels), and so the bandwidth required is 18-24Mbps +overheads which exceeds the 12Mbps maximum limit imposed by USB 1.x.
