Suggestions for Linux-friendly BLE dongle?

This is all I get when I plug in the dongle:

[3709401.040967] usb 2-1.7: new full-speed USB device number 85 using ehci-pci
[3709401.158174] usb 2-1.7: New USB device found, idVendor=7392, idProduct=c611, bcdDevice= 2.00
[3709401.158180] usb 2-1.7: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[3709401.158182] usb 2-1.7: Product: Edimax Bluetooth Adapter
[3709401.158183] usb 2-1.7: Manufacturer: Realtek
[3709401.158185] usb 2-1.7: SerialNumber: 00E04C239987

No mention of any firmware loading here or in any of my system logs, so I have no idea which firmware file to target. :(
