My USB controller is:
ohci0: <SiS 5571 USB controller> mem 0xee000000-0xee000fff irq 20 at 
device 2.2
on pci0
ohci0: [GIANT-LOCKED]
usb0: <SiS 5571 USB controller> on ohci0
ohci1: <SiS 5571 USB controller> mem 0xee001000-0xee001fff irq 23 at 
device 2.3
on pci0
ohci1: [GIANT-LOCKED]
usb1: <SiS 5571 USB controller> on ohci1.
How to execute the idea set the flag USBD_FORCE_SHORT_XFER?
I do not found anything in the(sysctl, rc.conf, GENERIC), and what to 
correct in
the /usr/src/sys/dev/usb/ohci.c:    if ((flags & USBD_FORCE_SHORT_XFER) &&
i don't know.
Thanks in advance, Yuri
