VTL and physical tape library get stuck at mounting

I need a solution

Hi I have a new setup

with a physical tape library 4048 and a VTL emulated as ESL E-series and jobs to both get stuck at "mounting"

Netbackup 7.6.0.1 (windows 2012)

Below is the output I get from various commands before I configure the storage devices. 

c:\Program Files\Veritas\Volmgr\bin>tpautoconf.exe -t

Issue I am having is that while configuring devices the drives dont show as attached to the tape library and lists as standalone.I manually try and add the drives to each robot and seems to work only that during the backup test the job is stuck at mounting for VTL and MSL library. 

Couple of things I noticed.. 

1) In the above output of scan the 2nd changer (VTL) doesnt show any device name or pass thru name.. 

Under device manager this shows up as unknown medium changer even though the drivers are installed and i cant seem to get it to change.

2) While configuring the MSL 4048 library using the device config wizrd in the box where it shows "review the devices netbackup has found" the MSL has an red X sign stating unusable. When i check the properties it shows "Illegal drive type in robot."

But this is a standard MSL 4048 HP tape library with LTO6 tape drives . 

I dont see any hardware related errors in event logs. 

Any suggestions..for both these issues ?

Thanks
