Sometimes it's not always the software to blame.
Glad you got it going. Marking as [WorksForMe].

Thanks for your time and help socratis and mpack.

Hi socratis,
I bought another sd card reader on amazon, it arrived late yesterday.
It seems to be staying connected without issue.
So I think the root issue is with the Kingston Card reader FCR-HS3.
The new reader works fine.
No need to investigate on my behalf any longer.

And finally, besides that basic USB information asked before, I would like to see a "VBox.log. zip " from a complete run for the VM: Start the VM from cold-boot (not from a paused or saved state) / Observe error / Shutdown the VM. With the VM completely shut down (not paused or saved) , r...

I would like to see some information with the use of the USB filters. So, create a filter, and if you still have a problem after reading through the whole FAQ, please provide the information requested in the last post . No need to repeat information already provided in your first post. C:\Program F...

I will work on this later today.

Clarification:
The fat32 partition is view-able and navigable in windows. The ext4 partition is not.

Trying to mount ext4 partition gives the following error:
$ sudo mount -t vboxsf I_DRIVE rootfs
/sbin/mount.vboxsf: mounting failed with the error: Protocol error

Correction: The shared folders idea does not work at all. I forgot to remove the USB filter. My mistake.

Actually it works for the fat32 partition but does not for the ext4 partition.

Update again: If I unmount within Ubuntu file manager, the partitions are no longer locked in gparted, and are available as read/write in gparted temporarily. However, the random unmounting occurs again, so the partitions or drive are no longer accessible in the VM.

Unfortunately, The drives are no longer read/write, they are read only. I am using gparted in Ubuntu VM. I can no longer repartition or manipulate the drives if they are shared folders. So the shared folders solution works if I only want to read the drives, but usually I will need to write and manip...

Windows sees the drives but cannot navigate because of the formatting, fat32 and ext4.

Try accessing the drive as a shared folder. Hi mpack, I do not know how to do this. Windows does not see the drive correctly for some reason. So I can't navigate to it and add it as a shared folder. I will try this with another SD Card today. Update: the cards are not visible to windows without for...

Hello, I am seeing my USB 3.0 SD card reader unmount randomly while using it in an Ubuntu 16LTS guest on a Windows 10 host. I have tried using a filter with only Vendor ID and Product ID. I have tried not using a filter and attaching using Devices->USB->Kingston... while the VM is running. I have tr...
