USB drivers build 11.06 have been released (12/23/2013) on the eComStation Betazone; also publicly available (9/28/2013) is build 10.196 (despite the version number difference, they are based on the same code). These drivers now feature support for isochronous devices, such as webcams. They also have improved hardware compatibility, including proper PCI PM (power management) support. This allows USB ports to be used when warm booting from Windows, which can sometimes leave them in a powered down state.
