Public bug reported:
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.
