Public bug reported:
Summary
The Goodix fingerprint reader 27c6:63AC ("Goodix USB2.0 MISC") worked correctly
on Ubuntu 22.04 (libfprint 1.90.x / 1.94.3) and is completely broken on Ubuntu
24.04 (libfprint 1.94.7+tod1). Every enroll attempt fails with "Corrupted
message header received". The regression was introduced when 63AC was added to
goodixmoc's PID table in the impish SRU (LP #1945296).
Hardware
Dell XPS 15 9510 (also reported on Dell Precision 5760 — same sensor)

Steps to reproduce
Fresh Ubuntu 24.04 install, libfprint 1.94.7+tod1-0ubuntu5
Open Settings → Users → Fingerprint Login, or run fprintd-enroll -f
right-index-finger
Result
Using device /net/reactivated/Fprint/Device/0
failed to claim device: GDBus.Error:net.reactivated.Fprint.Error.Internal: Open
failed with error: Corrupted message header received
Failure is deterministic from cold boot — not a suspend/stuck-state issue.
Expected result
Fingerprint enroll succeeds, as it did on Ubuntu 22.04 with the same hardware.
Debug output (G_MESSAGES_DEBUG=all fprintd)
libfprint-context-DEBUG: Initializing FpContext (libfprint version 1.94.7+tod1)
libfprint-tod-DEBUG: Opening driver

libfprint-context-DEBUG: No driver found for USB device 27C6:63AC
Note: when Dell TOD blob libfprint-2-tod1-goodix 0.0.6 is installed,
libfprint loads the 53xc TOD driver but still reports "No driver found
for 27C6:63AC" — the 53xc blob does not cover the 63xx PID family. The
device then falls through to goodixmoc, which claims it and fails.
Root cause analysis
On Ubuntu 22.04, libfprint 1.90.x did not include 63AC in goodixmoc's PID
table. The device was handled correctly by a different path.
63AC was added to goodixmoc in the impish SRU (LP #1945296, commit adding
0x63AC to goodix.c device table).
On noble's libfprint 1.94.7, goodixmoc claims the device (confirmed via /proc
and debug output) but sends an initialization sequence the sensor rejects —
protocol mismatch producing "Corrupted message header received".
Dell's OEM TOD blob (libfprint-2-tod1-goodix 0.0.6) covers only the 53xc PID
family and does not cover 63AC. There is no TOD driver for this sensor in the
Dell archive.
A udev ENV{LIBFPRINT_DRIVER} rule cannot override the compiled-in goodixmoc
precedence.
Workaround
None available. Fingerprint login is non-functional on noble for this hardware.
