Tvheadend + it913x "unable to open demuxer "/dev/dvb/ adapter0/ demux0" for pid X -- Too many open files"

HU:

Mar reg akartam magamnak egy DVR cuccot, ugyhogy gondoltam nem nagy osszeg ket DVB-T vevot venni es bele tolni az amugy allandoan mukodo otthoni storage gepembe. A tortenethez hozzatartozik, hogy a gepben egy alacsony fogyasztasu Via Epia M10000-es van, aminek csak 1db USB2.0 hub-ja van :/.
USB 1.0-as portba dugva tvheadend az alabbi hibakat dobja. A tvheadend kodjanak bongeszese utan es a driver kodjanak bongeszese utan a fejemet fogva helyeztem at a 2 vevot a 2.0-as portokba. Persze a muanyag burkolatuk miatt nem fernek el sehogy egymas mellett, ugyhogy azt le kellett kapni roluk.

Tanulsag: Mielott barmit bedugsz, elotte ellenorizd a port sebesseget! :)

I had long wanted to configure a DVR system, with two DVB-T receivers using tvheadend on my otherwise constantly working home storage server. The machine has a low-power VIA EPIA M10000 MB, with only one USB 2.0 hub ... yeah :/

I've plugged the receivers into the USB 1.0 ports and when choosing a channel tvheadend threw the errors below. After browsing the code of tvheadend and the driver's code, I've found out that this stick will not work with USB 1.0.

Lesson to be learned: Before you plug it in, check your port speed! :)

Nekem egy LV52T van (LifeView vagy NotOnlyTV márkájú, nem teljesen tiszta a kettő kapcsolata). Ez alapból egy dual af9015 tuner, és talán egy ezressel volt drágább, mint a szimpla tuner. Jó kis cucc.
