Sandisk Mini USB Disconnects when Laptop Suspends on Battery
https://askubuntu.com/questions/1559554/sandisk-mini-usb-disconnects-when-laptop-suspends-on-battery
I have a 128Gb Sandisk mini USB device that I am using for extra storage on an old Lenovo V145-15AST (model 81MT) running Xubuntu 24.04.2.
I have it mounted using fstab and everything works as intended.
# mount Sandisk 128Gb USB
/dev/disk/by-uuid/3936-3889 /media/Sandisk auto x-gvfs-name=USB-Sandisk,x-gvfs-show,uid=1000,gid=1000 0 1
Initially, the presence of the USB drive would cause the system to hang when waking from suspend, but only when running on battery power. The following command
echo "XHC0" | sudo tee /proc/acpi/wakeup
fixed the problem, so that is now automated on startup.
Then I noticed that the USB device would just "disappear" if I left it suspended on battery for longer than an hour. I assume that is to do with power states and entering a deeper suspend/freeze. So I tried disabling auto-suspend by editing GRUB.
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbcore.autosuspend=-1"
And checking
cat /sys/module/usbcore/parameters/autosuspend
gives -1 on a reboot.
lsusb gives the following:
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 002: ID 0438:7900 Advanced Micro Devices, Inc. Root Hub
Bus 002 Device 003: ID 0bda:c024 Realtek Semiconductor Corp. Bluetooth Radio

Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 004: ID 0781:5583 SanDisk Corp. Ultra Fit
So I added the below rule to /etc/udev/rules.d/92-usb-input-no-powersave.rules
ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="0781", ATTR{idProduct}=="5583", TEST=="power/control", ATTR{power/control}="on"
I also tried with SUBSYSTEMS=="usb", but the USB device is still powered off after an hour. (again, this only happens on battery power).
udevadm info -a /dev/sda
outputs the below:

I notice from some manual experimenting with unmounting/remounting and unbinding/rebinding that the sda block is simply gone, and after a replug the drive is reconfigured under sdc (sdb is the main internal drive). Issuing the below on a normal working system:
echo 0000:00:10.0 > /sys/bus/pci/drivers/xhci_hcd/unbind
then suspending the system for a while before waking then issuing
echo 0000:00:10.0 > /sys/bus/pci/drivers/xhci_hcd/bind
works fine IF the system wake happens before an hour elapses (I think it was an hour but I could be wrong on the exact time it takes to enter a deeper suspend state). At any rate, if I leave it suspended for too long on battery the block device disappears.

[ 1317.047065] scsi 2:0:0:0: Device offlined - not ready after error recovery
So this appears to be the problem:
[ 1296.296102] FAT-fs (sdb1): unable to read boot sector to mark fs as dirty
and then a few lines later:
[ 1317.047065] scsi 2:0:0:0: Device offlined - not ready after error recovery
After a replug and running
sudo fsck.vfat -a /dev/sdb1
Gives this:
fsck.fat 4.2 (2021-01-31)
There are differences between boot sector and its backup.
This is mostly harmless. Differences: (offset:original/backup)
65:01/00
Not automatically fixing this.
Dirty bit is set. Fs was not properly unmounted and some data may be corrupt.
Automatically removing dirty bit.
*** Filesystem was changed ***
Writing changes.
/dev/sdb1: 4083 files, 912858/3754218 clusters
So I will double check and add the below to the
/lib/systemd/system-sleep folder:
#!/bin/sh
# rebind sandisk usb
case "$1" in
pre)
# unmount sandisk usb before suspend
umount /dev/disk/by-uuid/3936-3889
;;
post)
# rebind sandisk usb when waking
sleep 1
mount /dev/disk/by-uuid/3936-3889
;;
esac
This isn't a huge deal since I don't often suspend on battery for any great length of time, and a replug of the USB device is all that is necessary. However, it does happen occasionally and I would prefer to minimise physical replugging if there is another way.
Any ideas? I suspect it might not be possible with that USB device and the 'proper' solution is a bigger SSD. Still, I am open to suggestions.
TIA
EDIT I have added the fstab entry above and dmesg logs of a clean suspend/resume on power versus a failed suspend/resume on battery. I am also going to change the drive from fat to ext4 and retest.
