If an afatech 9015 stick is connected, such as an AverTV Volar Black HD (A850), it will be recognized and doesn't affect the other device. *But* it runs into trouble if the two devices were connected at bootup, or if the Cinergy stick is inserted after the other one : ----------------------------------------------------------------------- [ 1.264018] usb 2-1: new high speed USB device using ehci_hcd and address 2 [ 1.382487] usb 2-1: New USB device found, idVendor=0ccd, idProduct=0099 [ 1.382490] usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 1.382492] usb 2-1: Product: DVB-T TV Stick [ 1.382494] usb 2-1: Manufacturer: ITE Technologies, Inc.
