I'm using several USB devices on a little ODROID running Gentoo:> uname3.10.80> lsusbBus 001 Device 005: ID 1b71:0056 FushicaiBus 001 Device 004: ID 0bda:2832 Realtek Semiconductor Corp. RTL2832U DVB-TBus 001 Device 003: ID 0bda:8812 Realtek Semiconductor Corp. RTL8812AU     802.11a/b/g/n/ac WLAN AdapterBus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hubBus 001 Device 002: ID 05e3:0610 Genesys Logic, Inc. 4-port hubBus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hubThe Fushicai is a little USB webcam whish is proven to work on this hardware and kernel. The RTL2832U DVB-T is used by some proprietary software to decode aviation radio comm.Unfortunately, uvcvideo locks onto RTL2832U DVB-T and ignores the Fushicai device. Is there a way to configure uvcvideo to do it the other way round, some sort of uvcvideo blacklist and whitelist?Here's the dmesg output after plugging the camera with no other USB device connected:[   54.790233] usb 1-1.1: new high-speed USB device number 3 using dwc_otg[   55.043458] uvcvideo: Found UVC 1.00 device <unnamed> (0000:0000)[   55.043470] ------------[ cut here ]------------[   55.043486] WARNING: at drivers/media/media-device.c:375 media_device_register+0x64/0xd8()[   55.043491] Modules linked in: snd_usbmidi_lib uvcvideo(+) snd_rawmidi snd_seq_device videobuf2_vmalloc nf_conntrack_ipv4 nf_defrag_ipv4 iptable_filter ip_tables nf_conntrack_ipv6 nf_defrag_ipv6 xt_conntrack nf_conntrack ip6table_filter ip6_tables w1_gpio wire aml_gpio[   55.043537] CPU: 3 PID: 2135 Comm: systemd-udevd Not tainted 3.10.80-odroidc1 #16[   55.043566] [<c0014e64>] (unwind_backtrace+0x0/0xec) from [<c0011ea0>] (show_stack+0x10/0x14)[   55.043581] [<c0011ea0>] (show_stack+0x10/0x14) from [<c002d848>] (warn_slowpath_common+0x54/0x6c)[   55.043593] [<c002d848>] (warn_slowpath_common+0x54/0x6c) from [<c002d8fc>] (warn_slowpath_null+0x1c/0x24)[   55.043605] [<c002d8fc>] (warn_slowpath_null+0x1c/0x24) from [<c0313708>] (media_device_register+0x64/0xd8)[   55.043639] [<c0313708>] (media_device_register+0x64/0xd8) from [<bf07afe4>] (uvc_probe+0x4c4/0xd70 [uvcvideo])[   55.043792] [<bf07afe4>] (uvc_probe+0x4c4/0xd70 [uvcvideo]) from [<c02dacc0>] (usb_probe_interface+0x16c/0x244)[   55.043823] [<c02dacc0>] (usb_probe_interface+0x16c/0x244) from [<c028adfc>] (driver_probe_device+0xd4/0x21c)[   55.043836] [<c028adfc>] (driver_probe_device+0xd4/0x21c) from [<c028aff0>] (__driver_attach+0x68/0x8c)[   55.043851] [<c028aff0>] (__driver_attach+0x68/0x8c) from [<c02892b0>] (bus_for_each_dev+0x4c/0xa4)[   55.043864] [<c02892b0>] (bus_for_each_dev+0x4c/0xa4) from [<c028a4e8>] (bus_add_driver+0xd0/0x258)[   55.043877] [<c028a4e8>] (bus_add_driver+0xd0/0x258) from [<c028b60c>] (driver_register+0xa8/0x140)[   55.043888] [<c028b60c>] (driver_register+0xa8/0x140) from [<c02d99bc>] (usb_register_driver+0x70/0x128)[   55.043913] [<c02d99bc>] (usb_register_driver+0x70/0x128) from [<bf08c020>] (uvc_init+0x20/0x4c [uvcvideo])[   55.043947] [<bf08c020>] (uvc_init+0x20/0x4c [uvcvideo]) from [<c0008544>] (do_one_initcall+0xa0/0x148)[   55.043964] [<c0008544>] (do_one_initcall+0xa0/0x148) from [<c0082854>] (load_module+0xbbc/0xf78)[   55.043978] [<c0082854>] (load_module+0xbbc/0xf78) from [<c0082d54>] (SyS_finit_module+0x60/0x70)[   55.043991] [<c0082d54>] (SyS_finit_module+0x60/0x70) from [<c000e000>] (ret_fast_syscall+0x0/0x38)[   55.043998] ---[ end trace e93c02068fb3ea25 ]---[   55.044391] usbcore: registered new interface driver uvcvideo[   55.044401] USB Video Class driver (1.1.1)[   55.076760] 3:3:1: cannot get freq at ep 0x84[   55.094503] usbcore: registered new interface driver snd-usb-audioAnd this is what's loaded afterwards:Module                  Size  Used bysnd_usb_audio         121616  0snd_hwdep               5819  1 snd_usb_audiosnd_usbmidi_lib        17238  1 snd_usb_audiouvcvideo               70500  0snd_rawmidi            19419  1 snd_usbmidi_libsnd_seq_device          5968  1 snd_rawmidivideobuf2_vmalloc       2747  1 uvcvideonf_conntrack_ipv4      13630  1nf_defrag_ipv4          1310  1 nf_conntrack_ipv4iptable_filter          1540  1ip_tables              11650  1 iptable_filternf_conntrack_ipv6       8123  1nf_defrag_ipv6         14338  1 nf_conntrack_ipv6xt_conntrack            2899  2nf_conntrack           81773  3 xt_conntrack,nf_conntrack_ipv4,nf_conntrack_ipv6ip6table_filter         1489  1ip6_tables             11914  1 ip6table_filterw1_gpio                 3326  0wire                   20699  1 w1_gpioaml_gpio                7825  0
