Firstly, ESXi 5.5 does not supported the direct attachment of tape drives to the host server.

see here

Note: As per the vSphere 5.x Release Notes, VMware does not support Tape Drives connected directly to ESXi 5.x.

The recommended method of attaching a tape drive to a virtual machine is:-

1. use a SCSI Inititor (SCSI card)
2, connect the tape drive directly to the SCSI card.
3. Present the SCSI Card directly to the VM using VM Direct Path I/O e.g. PCI Passthrough.

The above is recommended by Symantec and Overland as the only way to attach tape drives to VMs

checkout this example of PCI passthrough using a USB PCI card as an example:-

Checkout these documents on USB passthrough

Only a few serverfs supported PCI Passthrough (VM Direct Path I/O)
