In rev 1.51 of usb_port.h I switched over to using the USB_USE_SOFTINTR
code path to fix a bug in the non USB_USE_SOFTINTR path that caused the usb bus to hang and generally misbehave when devices were unplugged. In the process though it also reduced the throughput of usb devices because of a less than optimal implementation under FreeBSD. This commit fixes the non USB_USE_SOFTINTR code in uhci and ohci so that it works again, and switches back to using this code path. The uhci code has been tested, but the ohci code hasn't. It's essentially the same anyway and so I don't envisage any difficulties. Code for uhci submitted by: Maksim Yevmenkin <myevmenk@exodus.net>
