Hi there,
I have a Hauppauge Nova-T 500 that is displaying some odd behaviour.
Often the device fails to tune after rebooting the host machine, due to
a failure to load firmware.
when the firmware fails to load, dmesg shows:
dib0700: loaded with support for 9 different device-types
dvb-usb: found a 'Hauppauge Nova-T 500 Dual DVB-T' in cold state, will
try to load a firmware
dvb-usb: downloading firmware from file 'dvb-usb-dib0700-1.20.fw'
dib0700: firmware download failed at 7 with -22
usbcore: registered new interface driver dvb_usb_dib0700
When firmware loading is successful I see:
dib0700: loaded with support for 9 different device-types
dvb-usb: found a 'Hauppauge Nova-T 500 Dual DVB-T' in warm state.
dvb-usb: will pass the complete MPEG2 transport stream to the software
demuxer.
DVB: registering new adapter (Hauppauge Nova-T 500 Dual DVB-T)
DVB: registering adapter 1 frontend 0 (DiBcom 3000MC/P)...
MT2060: successfully identified (IF1 = 1242)
dvb-usb: will pass the complete MPEG2 transport stream to the software
demuxer.

DVB: registering adapter 2 frontend 0 (DiBcom 3000MC/P)...
MT2060: successfully identified (IF1 = 1233)
input: IR-receiver inside an USB DVB receiver as /class/input/input7
dvb-usb: schedule remote query interval to 50 msecs.
dvb-usb: Hauppauge Nova-T 500 Dual DVB-T successfully initialized and
connected.
usbcore: registered new interface driver dvb_usb_dib0700
Powering down the host machine seems to help as, so far, I have 100%
success when restarting this way, whereas after reboot the success is
much lower, firmware failing to load maybe 50% of the time.
Has anyone seen this behaviour before, any advice on what the cause
might be?
Many thanks,
Lou
