Well, after answering first time i checked again and find that patch for usbhid that forces usbhid not to touch this device already in upstream kernel. It is "HID: don't allow DealExtreme usb-radio be handled by usb hid driver". > Lets see if Fedora 10 have newer Kernel, if not I will try to install it > from delvel system (rawhide).

Let's check again. You plug device in, make rmmod radio-si470x, then you unplug radio and plug again ? Dmesg shows you that radio-si470x is loaded ? But you have no sound, right ? There is also should be snd-usb-audio module loaded. Please read Documentation/video4linux/si470x.txt. Please, tell us problem in more clear way and let's wait Tobias or others answer. >> Tobias, what do you think about this issue ? >> > > regards > Antti > -- > http://palosaari.fi/ > > > Bus 002 Device 014: ID 10c5:819a Sanei Electric, Inc. > Device Descriptor: > bLength 18 > bDescriptorType 1 > bcdUSB 1.10 > bDeviceClass 0 (Defined at Interface level) > bDeviceSubClass 0 > bDeviceProtocol 0 > bMaxPacketSize0 64 > idVendor 0x10c5 Sanei Electric, Inc. > idProduct 0x819a > bcdDevice 1.00 > iManufacturer 1 www.rding.cn > iProduct 2 > iSerial 0 > bNumConfigurations 1 > Configuration Descriptor: > bLength 9 > bDescriptorType 2 > wTotalLength 145 > bNumInterfaces 3 > bConfigurationValue 1 > iConfiguration 0 > bmAttributes 0x80 > (Bus Powered) > MaxPower 100mA > Interface Descriptor: > bLength 9 > bDescriptorType 4 > bInterfaceNumber 0 > bAlternateSetting 0 > bNumEndpoints 0 > bInterfaceClass 1 Audio > bInterfaceSubClass 1 Control Device > bInterfaceProtocol 0 > iInterface 0 > AudioControl Interface Descriptor: > bLength 9 > bDescriptorType 36 > bDescriptorSubtype 1 (HEADER) > bcdADC 1.00 > wTotalLength 43 > bInCollection 1 > baInterfaceNr( 0) 1 > AudioControl Interface Descriptor: > bLength 12 > bDescriptorType 36 > bDescriptorSubtype 2 (INPUT_TERMINAL) > bTerminalID 1 > wTerminalType 0x0710 Radio Receiver > bAssocTerminal 0 > bNrChannels 2 > wChannelConfig 0x0003 > Left Front (L) > Right Front (R) > iChannelNames 0 > iTerminal 0 > AudioControl Interface Descriptor: > bLength 13 > bDescriptorType 36 > bDescriptorSubtype 6 (FEATURE_UNIT) > bUnitID 2 > bSourceID 1 > bControlSize 2 > bmaControls( 0) 0x01 > bmaControls( 0) 0x00 > Mute > bmaControls( 1) 0x00 > bmaControls( 1) 0x00 > bmaControls( 2) 0x00 > bmaControls( 2) 0x00 > iFeature 0 > AudioControl Interface Descriptor: > bLength 9 > bDescriptorType 36 > bDescriptorSubtype 3 (OUTPUT_TERMINAL) > bTerminalID 3 > wTerminalType 0x0101 USB Streaming > bAssocTerminal 0 > bSourceID 2 > iTerminal 0 > Interface Descriptor: > bLength 9 > bDescriptorType 4 > bInterfaceNumber 1 > bAlternateSetting 0 > bNumEndpoints 0 > bInterfaceClass 1 Audio > bInterfaceSubClass 2 Streaming > bInterfaceProtocol 0 > iInterface 0 > Interface Descriptor: > bLength 9 > bDescriptorType 4 > bInterfaceNumber 1 > bAlternateSetting 1 > bNumEndpoints 1 > bInterfaceClass 1 Audio > bInterfaceSubClass 2 Streaming > bInterfaceProtocol 0 > iInterface 0 > AudioStreaming Interface Descriptor: > bLength 7 > bDescriptorType 36 > bDescriptorSubtype 1 (AS_GENERAL) > bTerminalLink 3 > bDelay 0 frames > wFormatTag 1 PCM > AudioStreaming Interface Descriptor: > bLength 11 > bDescriptorType 36 > bDescriptorSubtype 2 (FORMAT_TYPE) > bFormatType 1 (FORMAT_TYPE_I) > bNrChannels 2 > bSubframeSize 2 > bBitResolution 16 > bSamFreqType 1 Discrete > tSamFreq[ 0] 96000 > Endpoint Descriptor: > bLength 9 > bDescriptorType 5 > bEndpointAddress 0x83 EP 3 IN > bmAttributes 5 > Transfer Type Isochronous > Synch Type Asynchronous > Usage Type Data > wMaxPacketSize 0x0200 1x 512 bytes > bInterval 1 > bRefresh 0 > bSynchAddress 0 > AudioControl Endpoint Descriptor: > bLength 7 > bDescriptorType 37 > bDescriptorSubtype 1 (EP_GENERAL) > bmAttributes 0x00 > bLockDelayUnits 2 Decoded PCM samples > wLockDelay 0 Decoded PCM samples > Interface Descriptor: > bLength 9 > bDescriptorType 4 > bInterfaceNumber 2 > bAlternateSetting 0 > bNumEndpoints 2 > bInterfaceClass 3 Human Interface Device > bInterfaceSubClass 0 No Subclass > bInterfaceProtocol 0 None > iInterface 0 > HID Device Descriptor: > bLength 9 > bDescriptorType 33 > bcdHID 1.11 > bCountryCode 0 Not supported > bNumDescriptors 1 > bDescriptorType 34 Report > wDescriptorLength 203 > Report Descriptors: > ** UNAVAILABLE ** > Endpoint Descriptor: > bLength 7 > bDescriptorType 5 > bEndpointAddress 0x81 EP 1 IN > bmAttributes 3 > Transfer Type Interrupt > Synch Type None > Usage Type Data > wMaxPacketSize 0x0040 1x 64 bytes > bInterval 10 > Endpoint Descriptor: > bLength 7 > bDescriptorType 5 > bEndpointAddress 0x02 EP 2 OUT > bmAttributes 3 > Transfer Type Interrupt > Synch Type None > Usage Type Data > wMaxPacketSize 0x0040 1x 64 bytes > bInterval 1 > Device Status: 0x0000 > (Bus Powered) P.S.
