[SOLVED] Powering on before TV

[IriDium]

If it works, it works. However, erratic behaviour will occur if your electricity company lowers your supply voltage - which they will do in times of stress. (The POOR people!)

If Virgin follow the USB guidelines, it should only output 500ma - See Virgin media

I guess a lot depends on the manufacturer of your model.

The only way to be sure is to measure the current on startup.

You could also test it, by adding another USB device to the RPi (Say a Wifi dongle)

I would also check dmesg and see if there are any USB related errors.

Still if it works - Don't touch it
