Ideally HDD, and DVB devices shouldn't share the the same controller. 

Most systems have two.

However, it is difficult for users know how these are assigned as
sockets on a motherboard, or whether just one is available externally.

With respect to af9015 devices it is are not alone, were messages are
lost by operations of other devices.

On the patchwork server is a patch for bus repeating on af9015 usb
bridge TIMEOUT or BUSY errors.
