That USB ID is in fact in the 'data base' of usb_modeswitch. It was
originally used for the Philips PicoPix 1020 Projector.
That's what you get when the same USB ID is used for multiple unrelated
devices ...
The clean solution would be to use additional USB attributes to try and
tell the projector apart from your storage adapter. I'll look around to
see if I can find a detailed lsusb output.
However:
Enabling the global switch "DisableSwitching" *should* have solved the problem
for you. If it didn't then there might be a problem with the Ubuntu fork of the
usb_modeswitch_dispatcher.

Title:
USB 3 NVMe SSD dongle doesn't flip
Status in usb-modeswitch package in Ubuntu:
Confirmed
Bug description:
I have a AM8180 AMicro adapter. It is an adapter for an M.2 SSD NVMe
disk to USB 3. It works fine on Windows, but on Ubuntu, when I plug it
in, the drive shows for a second then disappears. If I try to do fdisk
or gparted, it seems to lock something and I can't shutdown the laptop
(it is stuck on the Disk Management Unmounting step.
My info:
1) Release:
Description: Ubuntu 20.04 LTS
Release: 20.04
2) Package version:
usb-modeswitch:
Installed: 2.5.2+repack0-2ubuntu3
Candidate: 2.5.2+repack0-2ubuntu3
Version table:
*** 2.5.2+repack0-2ubuntu3 500
500 http://th.archive.ubuntu.com/ubuntu focal/main amd64 Packages
3) What I expect to happen:
I expect the drive to stay mounted
4) What happened instead:
The disk is mounted then immediately unmount. Before I create the partitions
in Windows, nothing mounted but the disk briefly appeared in the Disk Manager.
Attached is my (filtered) syslog when I plug to the USB-C (notice the message
advising to tell the developers about the model. Maybe it's just vendor info
missing).
I have modified 2 flags in /etc/usb_modeswitch.conf:
- DisableSwitching=0 changed to 1
- #SetStorageDelay=4 changed to un-commented
then restarted. That didn't help.
