I GOT IT TO WORK !!
Instead of disabling the 'FBV Shortboard Mk II' device, disable the 'USB Composite Device' to where the shortboard belongs
For example if the Shortboard has a hardware id of USB\VID_0E41&PID_5056&MI_00, then disable USB\VID_0E41&PID_5056 without the last &MI_00
That powers off the Shortboard and then to power it on just enable the disabled 'USB Composite Device'

Here's a cygwin command which disables the shortboard

devcon disable `devcon find 'USB*' | fgrep 'FBV Shortboard Mk II' | sed 's/\(USB\\\[^&]*&[^&]*\).*/\1/'`

And a command which reenables it

devcon enable `devcon findall 'USB*' | fgrep 'FBV Shortboard Mk II' | sed 's/\(USB\\\[^&]*&[^&]*\).*/\1/'`

If you put them on a script around your DAW launch, you can have your shortboard enabled during and only during your DAW session
