Is there any chance of CoreELEC supporting a PCTV USB DVB-S2 tuner like this?

I’ve inserted it, having swapped the cable from the internal tuner and it shows up in Tvheadend as a Montage Technology M88DS3103 and under TV adapters it has a green dot against it.
Under networks it shows 95 Muxes and 0 Services so am not sure if I can get it to rescan… Maybe a fresh install would be easiest to sort out
After a reinstall I did manage to view some channels but performance was appalling, although this may be because I used the wrong driver or the required firmware wasn’t loaded.
According to:-
https://www.linuxtv.org/wiki/index.php/Pinnacle_PCTV_DVB-S2_Stick_(461e)
some firmware is required and it is supposedly included in OpenELEC. How do I check if CoreELEC includes it?
Although, thinking about it can the same firmware be used on both Intel and ARM?
Isn’t the firmware device related it the software the software uploaded to the asic in the chip that makes it work. The Driver is os/procecssor family related.
I agree I have 2 DVB-T tuners and use a usb 3 powered hub without strange things happen. Also if you do a cold reboot I normally de-power the HUB to put the tuners into a cold state.
No the Firmware does not run on the computer / Coreelec box its the software that runs in the dvb-t/s stick/card. It is uploaded to the device when it is spotted on the USB bus in its cold state. I use the same firmware for my usb-t tuner on my PC as in my Coreelec box. The driver on the other hand is compiled for ARM or x86.
The firmware for my PCTV DVB-S2 stick is called dvb-demod-m88ds3103.fw
How can I tell if it is included in CoreELEC?
According to https://github.com/CoreELEC/dvb-firmware/tree/master/firmware which lists the firmware YES. Your USB may not provide enough power as mentioned or you could try other drivers such as crazy cat.
There’s an awful lot of firmware listed there 
…
My device comes with a power supply so it should have enough power, although I’m disappointed with its performance and wouldn’t recommend it to anyone.
Maybe I’ll try with a different driver. How do I tell which it’s using?
Yes I should have realised its a DVB-S Tuner so it needs another power supply to provide power for the LNB (dish). It’s in Addons/Program Addons/Coreelec Drivers. There are 3 different ones coreelec/crazycat and kernal if I remember you could try each until you find the best one.
