Password prompt does not show up for the device encrypted using EndPointSecurity, when plugged in, thus leaving the device unusable.
The issue can be reproduced as follows:
Plug in an encrypted device and the password prompt is shown.
Enter the password and use the device.
Remove the USB using Safely remove hardware and unplug the device.
Plug the device back in, the password prompt is not shown. When this happens the user can see and access E:\ which has
VolumeIgm.DWon it, but F:\ doesn't show up.
