Hello!
I have a problem with my WD My Passport Ultra, RPi2 and LibreELEC. It's a usb 3.0 drive that does not use external power(maybe drawing too much from the RPi2? But it lights up and i use 2.5A power which i have read should be enough)
I can't find it when it's plugged in. I am using extfat and it shows on windows.
Any ideas?
RPi2 usb hdd not working.

USB 2.0 ports have a 0.5 amps output by design, so depending on your external drive, this could be an issue. If you see an occasional coloured square in the top right corner of your screen, then you know the RPi is having power problems. External power is very much preferred though.
As far as the attached drive goes, connect it to your RPi and reboot. Get us the outcome from the following commands via SSH:
Codeblkid | pastebinit mount | pastebinit -
Do you have
Codemax_usb_current=1
in your config.txt?Without that the pi 2 will only supply 600mA over usb.
With it it's 1200mA (power supply permitting). -

The other way would have been to use a self-powered-USB hub.

DaVu in libreelec installed in a HTPC (i3 6100) only libreelec, is there any order to usb 3.0 makes 1200mA?

On a normal HTPC you get only what those USBs have. I don´t know any way how it might be possible to change the ampere at a normal PC. The RPi is different in that case as it´s a 'tool' for developers in the first glance. Thankfullly it´s very good to run LibreELEC (for example) on it. But regarding to that (that it´s for developers normally) it needs to be very flexible.
Maybe there is some way to change the ampere for USBs for a normal PC, but 1. I don´t know it and 2. I doubt it
