Re: Raspberry pi 2B+ Can't power USB HDD anymore

I cannot recommend that wd labs power kit because it "only" delivers 5V and not 5.1V. :( Nonsense. I have three Raspberries, one Zero (314GB drive) and two 3Bs (375GB drives) that all run from that power supply and they're 100% rock solid. Did you read the rest of the posting ? I don't think so.

Re: keyboard layout does not change

When you change the keyboard you make a change in the configuration stored on the SD card. If this change disappears after a reboot then it may well be possible that the card is faulty and your configuration change was not written permanently to the card.

Re: Setting up Pi with only Ethernet Cable and Desktop

Instead of messing with dhcp on windows, you could just set the windows nic to a static ip E.g 192.168.1.100 Then set the pi ip to 192.168.1.200 I can not recommend this. Theoretically you can dig into Windows and assign a fixed address but preferably not 192.168.0.x or 192.192.168.1.x because this...
