VT DSO-2820R USB Isolator

[BlacKnight]

I'm trying to use a VT DSO-2820R with a USB Isolator. The DSO-2820R works normally without the isolator. When I connect the DSO-2820R through the USB isolator the Multi-Instrument software recognises the DSO-2820R, but no data is acquired or displayed.

The USB isolator limits the USB bus to "Full Speed" at 12 Mbit/s. I am wondering whether the data rate is too slow for the DSO-2820R to operate.

Please confirm whether the DSO-2820R is designed to operate at USB full speed (12 Mbit/s) or not.

VT DSO-2820R works with USB2.0 only.
