Mobile phones in car

trying to do a number of things here:
1. Charge two phones, samsung galaxy and iphone
2. pipe sound from either phone via car ICE

the usb+3.5mm stereo to iphone connectors are powered via a cigar socket to usb adaptor which has an additional usb A type socket soldered to it’s board

freesat mythtv firmware hauppage problem

Although the card is seen on the system, and in Mythtv, the Hauppage DVB-S2 tuner needs some non-free firmware to make it work:
cat /var/log/kern.log
Apr 7 08:35:22 mythserver kernel: [ 711.136979] cx24116_firmware_ondemand: Waiting for firmware upload (dvb-fe-cx24116.fw)...
Apr 7 08:35:22 mythserver kernel: [ 711.140459] cx24116_firmware_ondemand: Waiting for firmware upload(2)...
Apr 7 08:35:22 mythserver kernel: [ 711.140466] cx24116_firmware_ondemand: No firmware uploaded (timeout or file not found?)
Apr 7 08:35:22 mythserver kernel: [ 711.140473] cx24116_cmd_execute(): Unable initialise the firmware

It won’t tune until the firmware is installed, so:
sudo apt-get install linux-firmware-nonfree

Reboot, then :
markp@mythserver:~$ dmesg | grep cx24116
