I have a DM04 DVB-S USB box which doesn't seem to be supported with the kernel 3.x dvb-usb-lmedm04 driver although it seems very close. The firmware is loaded the tuner seems to be identified but it fails to attach the tuner? It has a LME2510 chip and the tuner has Sharp F7HZ0194A on it. This is the debug trace: LME2510(C): Firmware Status: 6 (44) LME2510(C): FRM Loading dvb-usb-lme2510-s0194.fw file LME2510(C): FRM Starting Firmware Download LME2510(C): FRM Firmware Download Completed - Resetting Device usbcore: registered new interface driver LME2510C_DVB-S usb 1-2: USB disconnect, device number 3 usb 1-2: new high speed USB device number 7 using ehci_hcd usb 1-2: config 1 interface 0 altsetting 1 bulk endpoint 0x87 has invalid maxpacket 64 usb 1-2: config 1 interface 0 altsetting 1 bulk endpoint 0x3 has invalid maxpacket 64 usb 1-2: config 1 interface 0 altsetting 1 bulk endpoint 0x8A has invalid maxpacket 64 usb 1-2: config 1 interface 0 altsetting 1 bulk endpoint 0xA has invalid maxpacket 64usb 1-2: New USB device found, idVendor=3344, idProduct=1122 usb 1-2: New USB device strings: Mfr=0, Product=0, SerialNumber=3 usb 1-2: SerialNumber: 䥈児 LME2510(C): Firmware Status: 6 (47) dvb-usb: found a 'DM04_LME2510_DVB-S' in warm state. dvb-usb: will use the device's hardware PID filter (table count: 15).
