Hi,

No. Well, not with the protocol emulated here.
There is a new one for usb storage devices, designed with USB 3.0 in
mind and using streams (usb 3.0 feature) to handle multiple requests in
parallel. But I guess when ever implementing that it would be a new
device, not a usb-storage extension.
cheers,
Gerd
