The dpctl.MemoryUSM* Python object representing USM allocation are reconstructed from an object exposing __sycl_usm_array_interface__ use USM-pointer queries. When SUAI provides sycl::context object, the device is inferred using `get_pointer_device`. For host allocations this may not need to return the device in the queue used to make the allocation. It will return the first device in the context to which the allocation is bound instead (per SYCL 2020 spec).

The
dpctl.MemoryUSM*Python object representing USM allocation arereconstructed from an object exposing
__sycl_usm_array_interface__use USM-pointer queries. When SUAI provides
sycl::contextobject,the device is inferred using
get_pointer_device. For hostallocations this may not need to return the device in the queue used
to make the allocation. It will return the first device in the context
to which the allocation is bound instead (per SYCL 2020 spec).
This change will not affect test suite outcome on configurations where
platforms only have a single device it them.
