Help troubleshooting sys-usb drive connections

Problem: Some drives won’t mount or show in file explorer. Some other drives do.

Old USB drive connects:
Partitioning: master Boot Record
Format: Fat32

New USB drives stopped connecting:
Format: ext4, encrypted.

Another drive:
Format: ex4, non-encypted

Gnome disks shows the drives, but shows “no media”, and no options to format or mount.

lsblk doesn’t show the drives.

All drives did mount in the past with no problems. Nothing has changed with the drives. Something changed with sys-usb, or the sys-usb template.

Recreating sys-usb didn’t solve it.
Restoring old sys-usb from backups didn’t solve it.

When trying to connect drive, fans go crazy, computer freezes up for a moment.

What do all these symptoms add up to?

Changing the kernel of sys-usb to 6.6.42 fixed my USB drive not showing up and the system freezing

seems to be correlated with Fedora; I’ve the same issue, only with Fed40,
Deb12 is working.

I’m using Deb12… tested Deb11… same problem. Some old drives still connect. New drives that connected before aren’t connecting. Can I assume the problem is isolated to sys-usb and/or the sys-usb template? Or could something be happening further upstream?

5

Deleting sys-usb, and recreating from scratch didn’t solve it. The same symptoms persist. Can I assume the problem is not with sys-usb, but elsewhere?

Seems the problem is isolated to newer drives that have partitions. I used kpart to partition these drives.

Older drives without partitions are mounting.

What is missing from the sys-usb template, and/or changed to make it stop seeing those partitioned drives when attached?
