It'll be odd if it turns out to be the legacy driver - maybe he has motherboard-based Firewire ports?
That wasn't it, but if it had been I would not have been surprised. I have four PCs at home with TI based firewire cards and all of them only work with the Legacy driver. If I use the Windows 10 driver I cannot get them to transfer video without dropouts. It always seems to be a crapshoot.
Hmm...FWIW - device manager here reports that the SIIG card I'm using has a VIA OHCI Host Controller.
Apparently, it's using the stock Microsoft Windows provided driver, version 10.0.10586.0, dated 6/21/2006.
