This fixes the hangs in the USB driver.
The code mistakenly uses USBD_DEFAULT_INTERVAL which is -1, however
timeout is unsigned resulting in an absurdly long timeout. It really
wants to use USBD_DEFAULT_TIMEOUT.
After this I no longer get hung processes, however for some reason
the 3rd open of my printer makes it flake out. It seems to be NetBSD's
fault because power cycling the printer doesn't help (port gets
disabled due to error), however power cycling the netbsd box fixes
*sigh* If anyone wants to know, i'm using an 'ohci' controller and
