I finally upgrade my 24.04 to 24.10, and now fstrim fails. I have the
udev rules for all my USB SSDs, one old SATA two newer MVMe:
# cat /etc/udev/rules.d/10-uas-discard.rules
# Enable TRIM support for USB SSD enclosures.

ACTION=="add|change", ATTRS{idVendor}=="174c", ATTRS{idProduct}=="2362",

I don't think the message about an SSD not being an MTP device is
relevant, but here you have it ;-)
Here is what fstrim thinks now:
# fstrim --verbose /mnt
fstrim: /mnt: the discard operation is not supported

Right now I'm assuming that the UDev lines are not sufficient anymore.
Google does not find anything releated to Ubuntu oracular usb trim.

No TRIM via USB

Bug description:
Hi,
As USB attached SSDs are becoming quite big and affordable, along comes the
idea of installing systems on these.
But with current USB drivers, some functionality seems to be missing from USB
subsystem.
The system does not recognize it is an SSD, but it is corrected manually:
# cat /etc/udev/rules.d/10-forcessd.rules
SUBSYSTEM=="block", ATTRS{vendor}=="SanDisk", ATTRS{model}=="Extreme",
KERNEL=="sd?", ATTR{queue/rotational}="0"
# cat /sys/block/sdb/queue/rotational
0
Checked hdparm, it is saying I have TRIM on the device:
# hdparm -I /dev/sdb
/dev/sdb:
ATA device, with non-removable media
Model Number: SanDisk pSSD
(...)
Commands/features:
Enabled Supported:
(...)
* Data Set Management TRIM supported (limit 8 blocks)
* Deterministic read ZEROs after TRIM
(...)
Here is appropriate dmesg:

From here I'll be using /boot formatted to ext4 to eliminate luks,lvm
and btrfs from the equasion:
# mount |grep sdb2
/dev/sdb2 on /boot type ext4 (rw,noexec,discard)
# fstrim -v /boot/
fstrim: /boot/: FITRIM ioctl failed: Operation not supported
# strace fstrim -v /boot/
(...)
open("/boot/", O_RDONLY) = 3
ioctl(3, FITRIM, 0x7fffdded85c0) = -1 EOPNOTSUPP (Operation not
supported)
(...)
During debugging, I've tried compiling a kernel with UAS module to
check, it booted, system was g changed with the trim - as it wouldn't
been used at all.
Any ideas why TRIM is not working on USB?
Any timeframes for possible fix?
Any workarounds maybe?
