Very good question....
Personally I did not yet test it, so can't say for sure.
Maybe somebody else?
Or I can recommend to ask Sharkoon directly. Not sure, but maybe they can confirm.
Ps. on the link you sent if you click on the Download button, you can download a firmware update for this product.
However, when started it shows "JMB2033x FW update" - which is related to JMicron chipset, not IS611 chip.... So maybe the "V2" means they replaced the chipset....
