With 16-bit samples at 48 kHz, a full-speed bus has just barely enough
bandwidth for one stream with eight channels, or seven on-channel
Due to bugs in the EHCI driver, using multiple full-speed audio devices
connected to one or more high-speed hubs connected to one controller is
likely to fail.
Try using multiple controllers, and forcing the hubs to work at full
speed by unloading the ehci_hcd module.
