controller hardware most likely present on UHCI chipsets aswell. The
bug manifests itself when issuing isochronous transfers and bulk
transfers towards the same device simultaneously. From time to time it
happens that either the completion IRQ was missing or that the
completion IRQ was happening before the ITD/SITD was completely
written back to memory. The workaround assumes that double buffered
isochronous transfers are used, and that a second interrupt is
generated at the beginning of the next isochronous transfer to
complete the previous one. Possibly skipping the interrupt at the last
isochronous frame is possible, but will then break single buffered
isochronous transfers. For now we can live with some extra interrupts.

definitions required to compile the FreeBSD USB stack. When the global USB
header file is included, no other USB header files will be included by

Use a boundary of zero, hence a PAGE_SIZE boundary
is implied by all memory allocations.
Background:
Busdma has problems to allocate more than PAGE_SIZE
bytes when the boundary is PAGE_SIZE bytes too.
Initially it was thought that a boundary of PAGE_SIZE
bytes will only affect loading of DMA memory, so that
segments get split correctly, but it also affects
allocation of DMA'able memory.
Solution:
USB can detect big segments and split them as required
by the USB code.
