/****************************************************************************
Bus interfce for USB CLIENT DRIVERS
*****************************************************************************/
/*
The following bus interface is defined for client drivers
as an alternative to linking directly with USBD
It provides interfaces that may be called at Raised IRQL
without allocating an IRP

USBPORT_SubmitIsoOutUrb(

Routine Description:
Service exported for Real-Time Thread support. Allows a driver
to submit a request without going thru IoCallDriver or allocating
an Irp.
Additionally the request is scheduled while at high IRQL. The driver
forfeits any packet level error information when calling this function.
IRQL = ANY
Arguments:
BusContext - Handle returned from get_bus_interface
Urb -

Routine Description:
Service Returns the Highest USBDI Interface Version supported
by the port driver.
Released Interface Vesrions are:
Win98Gold,usbd 0x00000102

Arguments:
VersionInformation - Ptr to USBD_VERSION_INFORMATION
HcdCapabilities - Ptr to ULONG that will be filled in with
the Host controller (port) driver capability flags.
