i've 8 hubs and each hubs has got 4 usb soundcards,
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 streams.
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.
