My laptop has a very small internal SSD so I have move /home to my SDXC card. I have the fstab set up as below. It works fine for awhile when I first boot up, but then it loses the mount and cant get it back.

I've tried all sorts of things from the web. I even turned off usb automount thinking maybe it was interfering, but no luck.

Im wondering if it is disabling the USB hub the SDXC communicates through over time. Any good suggestions on how to tell Ubuntu 18.04 nto to ever turn off USB or disconnect external drives?

   # /etc/fstab: static file system information.

# Use 'blkid' to print the universally unique identifier for a

# device; this may be used with UUID= as a more robust way to name devices

# that works even if disks are added and removed. See fstab(5).

# <file system> <mount point>   <type>  <options>       <dump>  <pass>

I got stalled at the first step...
This is the card's lsusb entry

I did a recursive grep and the product id 0x090c and its not in any of those files?

2ND UPDATE: grep -r 090c (no 0x) found the file and then these instructions seem to have fixed my issue!

3rD UPDATE: Half-way there. It doesnt drop when I disconnect power any more, but it still seemingly randomly drops during use :/

4th Update: removing tlp allowed this solution to set the control parameters to on reliably.... but it still drops the volume
