Reverting this patch will cause 14,7mA leak from the ISP1704 USB transceiver. I did test at the time that USB networking was ok on MeeGo 1.1 based (MeeGo community edition N900) release and this patch. Though can't help debugging this now, sorry.

If you guys are not concerned with use time, no problem with this patch.
