issued by the Host Controller Driver, as well as reflecting the current status of the Host
Controller. To the Host Controller Driver, it appears to be a "write to set" register. The Host
Controller must ensure that bits written as 1 become set in the register while bits written
as 0 remain unchanged in the register. The Host Controller Driver may issue multiple
distinct commands to the Host Controller without concern for corrupting previously issued
commands. The Host Controller Driver has normal read access to all bits.
Controller has detected the scheduling overrun error. This occurs when the Periodic list
does not complete before EOF. When a scheduling overrun error is detected, the Host
Controller increments the counter and sets the SchedulingOverrun field in the
HcInterruptStatus register.
The HcCommandStatus register is used by the Host Controller to receive commands
The SchedulingOverrunCount field indicates the number of frames with which the Host

These bits are incremented at each scheduling overrun error. It is
initialized to 00b and wraps around at 11b. This will be incremented
when a scheduling overrun is detected even if SchedulingOverrun in
HcInterruptStatus has already been set. This is used by HCD to
monitor any persistent scheduling problems.
This bit is set by the OS HCD to request a change of HC control. When
set, the HC will set the OwnershipChange field in HcInterruptStatus.
After the changeover, this bit is cleared and remains so until the next
request is made from the OS HCD.
