Hi all,
Banana Pi (original) Allwinner A20 based
======== Kernel 4.2.X USB bugs a show stopper =============
Fedora 22 and Centos 7
USB works BADLY.
My $9 Gigabyte K6150 keyboard works well but as soon as you plug in any other USB device,
every USB device stops.
My Gigabyte wireless keyboard and mouse combo doesn't work. Period.
A USB1 or USB2 hub is not 'seen'.
With kernel 3.x.x everything worked well!!

Re: Pi Software and Hardware issues, Linux
So you're using a Banana Pi, not Raspberry Pi. The thread title is somewhat generic and "Pi" is assumed to mean "Raspberry Pi", which it's not. Sorry to nitpick.
Every time I think about buying one of the knockoffs I read a post like this that makes me think "yeahh.. maybe not".

Re: Pi Software and Hardware issues, Linux
Successful operation of USB requires a good reliable power source. Often there is insufficient power budget left for USB peripheral operation and wall adapter ratings are questionable. I recommend you try a good power adapter capable of 2A to see if that solves your issue. The apple iPad adapter is a good example of a trustworthy 2A adapter.

When the "Raspberry Pi" family has a SATA interface, I will consider them. Period.
Yes, I have a Raspberry Pi, the 1st. with only 256Mb of RAM, sorry, useless.
My question to you is:
Have you tried an o/s with kernel 4.2 X with several USB devices ?
As a Repeater Controller, it needs USB audio dongles and serial adapters.

^^ I'd still trust an Apple power supply over a Chinese one any day.

I have a Pi 2 at home and it is almost fast enough to consider using as a desktop replacement. Almost. Rendering websites is still too slow for my liking though. But for $35 it is *extremely* capable. Having said that, I see a lot of people trying to turn their Pi into a NAS. The Pi is not well suited to that task, you should use an x86 motherboard instead.

Depends what you're trying to do with it. If you are trying to build something with strong SATA / Ethernet performance then you are better off with an x86 Mini-ITX motherboard. This isn't a deficiency of the Pi, it's simply that you're asking a $35 SBC to be something that it's not.Yes, I have a Raspberry Pi, the 1st. with only 256Mb of RAM, sorry, useless.

I run a Pi 2 running Raspbian Jessie in my car, and it uses a 4.1 kernel. The USB is fully loaded with a wireless keyboard/trackpad, lightning connector for my phone (for charging and personal hotspot over USB), a Wifi dongle running in AP mode and a GPS. Everything works perfectly.My question to you is:

Re: Pi Software and Hardware issues, Linux
Fixed
===== power ==== POWER ==== USB POWER ====
The Banana Pi has the capability to switch the power to the USB.
Problem is, their switch device looses too many volts.
So, I put a wire from my 5V in, direct to the USB socket pair, all fixed.
The Banana Pi is perfectly suitable for a NAS with ONE SATA disk.
Perhaps a 2nd disk on the 2nd USB port.
All good, Alan VK2ZIW

Re: Pi Software and Hardware issues, Linux
Then came kernel 4.15.X and the introduction of Power Management.
Laptop and tablet power management has introduced many driver changes.
NOT ALL GOOD.
Ubuntu 16.04 with kernel 4.15.0-39-generic on my PC, ASRock Q1900-ITX repeatedly just stops
until I unload the GUI and boot up, just command line.
systemctl isolate multi-user.target
systemctl enable multi-user.target
systemctl set-default multi-user.target
revert: systemctl set-default graphical.target
==== Pi ====
Here also, same problem, just freezes, Fedora Linux upsbox 4.18.0-0.rc8.git1.1.fc29.armv7hl
Now running fine without the GUI, but only with "systemctl set-default multi-user.target" as above.
Booting up with no HDMI screen or USB keyboard & mouse plugged in, doesn't help.
In both machines, I thought I had a SATA controller problem.
==== A Raspberry Pi 3 Killer ====
Have a look at the RockPro64 by the PINE64 group. It has a PCI-E slot for a SATA controller!
Now, 3x 13Tb SATA disks and an SSD....
