Input: I connected a Sony DSR-45 DVcam videotape deck to my Lenovo T440 PC using this adapter and the laptop image immediately displayed a vertically rolling Venetian blind image superimposed over the normal PC desktop image. Then  Windows7 displayed the following warning: \\"Power Surge On Hub Port - A USB device has exceeded the power limits of its hub port...\\".  I had purchased two units, so I tested the 2nd copy as a precaution, with the same error.<br /><br />Knowing that a vertically rolling Venetian blind effect is common to a ground loop between two AC powered video devices, I then tested the same scenario by connecting a Panasonic AG-DVX100B camcorder powered by battery to the Lenovo T440 PC, and got the same error message without the rolling Venetian blind visual image. Sony Vegas Pro video editing software did not recognize the connection to be compliant with IEEE-1394 firewire protocol. I cannot recommend this adapter unless the manufacturer can issue a software upload bug fix.

This device failed two bench tests using industry-standard video equipment
