I am using MyGica T230c DVB dongle using TvHeadEnd on LibreELEC 9.0.1,

I am receiving DVB-t broadcasts but I am unable to receive DVB-t2.

Check mux settings in TVH. Need set frequency, bandwidth and delivery system DVB-T2

virtual machine is evil

So some issues in xhci drivers in latest kernels.

i think all usb 2.0 ports in modern hw connected to usb 3.x host controller (xhci host drivers), but provide power restricted to usb 2.0 standard.

i have some old PC with Intel B75/Z77 chipsets - this contain separate usb 2.0 host controller (ehci) for usb 2.0 ports, and separate usb 3.0 host (xhci) for usb 3.0. All PC DVB USB devices work well in usb 3.0 ports, at least with LTS kernels (Ubuntu 14.04.x with 3.13, 4.4 kernels; Ubuntu 18.04 with 4.15)

So please provide info about usb host controller.

maybe windows driver not support this device, check usb ids in inf

use second frontend on adapter.

Hauppauge WinTv HD dual tuner support same as mainline media_tree

Look like need recompile drivers addon

usb 1-1.3: DVB: adapter 0 frontend 1 frequency 386000000 out of range (470000000..862000000)

So basically I can scan UHF channels but not the VHF (out of range)

Is there anything I can change to enable VHF on the DVB-C tuner ?

Fixed long time ago

this card contain USB 2.0 host controller Ic + 4x USB DVB tuners

crazycat I think this could be fixed by registering an rc-core device only for one of the 153b:1181 / 153b:1182 USB devices. Looks like the IR receiver is connected to both of the devices on the dual tuner card so enabling IR on both of them results in doubled IR events. Can you have a look at that?

so IR sensor connected to both Cypress FX2 ?

This fake info about firmware from file dvb-fe-ds3103.fw.

ds3k frontend driver have firmware inside

461/462e supported in official V4L DVB, but need external power for LNB. Both need some tuner/demod firmare files,
