Redirection of Bloomberg Keyboard is not fully supported. However, below steps can be tried to get it working :

1. Make sure two Bloomberg cables are connected on Bloomberg starboard keyboard(black keyboard).  C1448 to pc slot, C1546 to KVM slot.  Test to make sure fingerprint reader on keyboard works on local installed Bloomberg software.  Close Bloomberg software.

2. Install receiver 12.5 or later for Mac.

3. On Xendesktop controller policy, make sure “Client USB device redirection” is on “Allow”;  “Client USB device redirection rules” includes “Allow: VID=1188 PID=9535”.   Reboot the VDA if you didn't have these in place.

4. On Receiver Device tab, you should see "KVM" and "Bloomberg Starboard Keyboard Fingerprint Scanner" both listed and checked. 

This means the redirection working and you should see fingerprint scanner working successfully from Bloomberg software Tour Install |Biometric device test.
