Troubleshooting • Re: RPi Zero-W USB power

The phone only wants 100ma

I find that hard to believe, that may be the minimum it will charge/operate at (eg from a current limited charger) but it is unlikely to be the maximum load it is capable of.

Ah well, I can only quote what it reports via lsusb -v. Insignificant anyway considering that the USB power + is tied directly to 5V in.

I've also played with limiting the USB speed (via dwc_otg.speed) and this does help device recognition. But the devices don't seem to like USB1.1 and the selected operation mode (storage or ethernet) doesn't work. Probably a limitation in these cheap phones.

It's certainly a shame that the USB port is so limited on the Zero models. I'll stick with the old B+ instead.

Cheers,
Steven
