Public bug reported:
== Problem ==
The Intel Visual Sensing Controller (IVSC) on Arrow Lake uses ACPI device ID
INTC10B2, which is not present in the mei_vsc_hw driver's ACPI match
table. The current driver only supports: INTC1009 (Raptor Lake), INTC1058
(Tiger Lake), INTC1094 (Alder Lake), INTC10D0 (Meteor Lake).
Additionally, even after binary-patching the module to add INTC10B2 to the
match table, the driver cannot bind because INTC10B2 is on the USB/platform
bus, not SPI:
ACPI path: \_SB_.PC00.XHCI.RHUB.HS09.VGPO
Subsystem: platform bus
Modalias: acpi:INTC10B2:
The mei_vsc_hw driver (vsc-tp.c) is an SPI driver only. Arrow Lake has
moved the IVSC from SPI to USB, requiring a new USB transport driver.
In summary, the camera does not work in this pc
== Symptoms ==
- int3472-discrete INT3472:0c: cannot find GPIO chip INTC10B2:00, deferring
(repeated continuously from boot)
- INTC10B2:00 ACPI device exists but has no driver bound
- /dev/video0 exists (v4l2loopback) but produces no frames
- v4l2-relayd service runs but camera sensor is never powered on
== System Info ==

- v4l2loopback
== What is needed ==
A USB-based transport driver for the Arrow Lake IVSC (INTC10B2), similar to
the existing SPI-based vsc-tp.c but using the USB bus at XHCI.RHUB.HS09.
Alternatively, adding INTC10B2 support to the existing driver with a USB
transport path.
