736 When I connect a drive to the Allegro USB 3.0 PCIe card, my Bluetooth mouse gets sluggish or stops working.Mar-27-18
USB 3.0 is known to cause radio frequency interference on 2.4 GHz wireless devices. See USB Frequency Interference. There are several possible solutions:

1) Purchase a USB bluetooth dongle to replace internal bluetooth, connect it via a USB extension cable, and locate it away from the USB 3.0 storage unit. Sonnet has successfully tested this solution with an IOGear Model GBU421WM USB to Bluetooth adapter. You should be able to use any Macintosh-compatible bluetooth adapter.

2) Select a different hard drive case with better shielding.

3) You may try different USB 3.0 cables. A better-shielded, or a shorter, or a longer USB 3.0 cable may solve the issue.

4) Relocate the hard drive to the opposite side of the computer.

5) For the technically inclined, the intel white paper has additional ideas. Have aluminum foil handy.
