I tested again on a vanilla media_tree with Mauro's patch attached. Doesn't work. Dmesg output: [ 0.788387] kernel: usb 1-1: new high-speed USB device number 2 using ehci-pci [ 0.792384] kernel: usb 2-1: new high-speed USB device number 2 using xhci_hcd [ 0.944937] kernel: usb 2-1: New USB device found, idVendor=1d19, idProduct=0100, bcdDevice= 1.00 [ 0.944939] kernel: usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 0.944940] kernel: usb 2-1: Product: TS Aggregator [ 0.944941] kernel: usb 2-1: Manufacturer: ITE Tech., Inc.
