System Information
Operating system: Windows-10-10.0.19045-SP0 64 Bits
Graphics card: NVIDIA GeForce GTX 1650 SUPER/PCIe/SSE2 NVIDIA Corporation 4.6.0 NVIDIA 536.23

Blender Version
Broken: version: 4.0.2, branch: blender-v4.0-release, commit date: 2023-12-05 07:41, hash: 9be62e85b727
Worked: (newest version of Blender that worked as expected)

Short description of error
Blender does not display animated textures after importing a USD layer that contains time sampled inputs:file attribute on Shader prims. The Image Texture Node created in Blender does get created, but it's source is not set to Image Sequence with expected frame range.

First, here's a demo from usdview displaying static and animated textures using the attached zipped.usdz:

Here's what the imported shading network looks like in Blender. Note the black texture on the right (animated) plane. I added an "expected" node that displays the animated textures correctly when hooked up to the Base Color property.

The workaround I have for now is the modify the created Image Texture Node after import to have the correct settings for animated textures. I'm hopeful the USD importer can be patched so it's done for me.

Exact steps for others to reproduce the error

Import attached zipped.usdz to a new Blender scene using USD importer with default settings.
Enable viewport shading
Scrub timeline frames 1-3
Observe right hand plane is black with no textures being displayed
