Re: Power issues with powered hub

You could try to tape off (with cellotape) pin 1 of the USB connector connecting the PI to the HUB, thereby isolating the 5V of the hub and the PI, easier than cutting any wires, or desoldering the polyfuse. pin 1 is the last one right, if looking at the plug with the pins at the bottom? tried it a...

Re: Power issues with powered hub

well no luck trying all sorts of different configurations the only time I can get wifi dongle to work is if I plug it into the Raspberry Pi USB port and have the USB hub disconnected from the Pi as soon as the data-cable gets plugged in from the hub, the wifi adapter stops working, both from the hub...

Re: Power issues with powered hub

I had originally tried this (wifi in hub) and had same result, but this was before I found out it was power related. I will try some other configurations now to see if there is any difference. Btw I thought I read somewhere the exact opposite, that wifi adapters seemed to cause issues when used in h...

Re: Power issues with powered hub

yep, i've been doing this also, but the same issue. It doesn't seem to matter where the Raspberry Pi is powered from, as soon as the USB data-cable is plugged in from the hub to the Raspberry Pi something gets messed up with the Wifi (Wifi adapter is plugged directly into the Pi also, not the hub)

Power from powered USB hub?

Hi guys, I've come to realise I'll need a powered USB hub to power my portable HDD, so I am about to get one. Thing is, I'd really rather not take up 2 power sockets just to run the Raspberry Pi (3 inc tv), especially since it uses so little power. Is it possible to power the Raspberry Pi off one of...
