CUSBQueue::GetIntervalIndex bug

There isn't any valid "Interval" param for CUSBQueue::GetIntervalIndex(UCHAR Interval) which returns a value of 10 as "IntervalIndex" since "Interval" range is [1,255] due to UCHAR restrictions.

CUSBQUEUE::GetIntervalIndex: http://git.reactos.org/?p=reactos.git;a=blob;f=reactos/drivers/usb/usbehci/usb_queue.cpp;hb=a6eecd921d17e58321f72ef034c70c6a5b5c50b4#l374

PS: The returned value of GetIntervalIndex is used to access an element of the following array via m_InterruptQueueHeads[IntervalIndex];

Which is defined as an m_InterruptQueueHeads[EHCI_INTERRUPT_ENTRIES_COUNT]; aka m_InterruptQueueHeads[10+1].
