Hello. I have an UFX and the UbuntuStudio (16.04.4) in a VirtualBox with Windows as a host. I made the driver and firmware updates for Windows and it's fine. But in Linux, even with CC on, it's failing. On Jack setup I choose alsa driver and if the usb cab is connected I find the hd ufx as option in Interface, but without the cab it's not present. The use of CC, as I understand, is wireless. I also test with USB wireless (that used for mouse with notepad) - nothing. The manual refers about firmware update (21 or up) but as on the site there's only Windows and Mac versions I conclude that no one download for Linux is necessary. So what more beside the firmware update (in my case it's on the host) and CC on is necessary?

Thanks
Marcelo
