Wake up USB device after sleep? - Shield Q&A

I use my Nvidia Shield as a media center. I´ve tried with two RF connected USB devices (Keyboard and Gamepad) and none of them will work unless I reconnect them after the Shield has gone to sleep. Otherwise they work just as expected : )
Any ideas on how to solve this? Am I the only one with this issue?
Edit: To clear things up - both devices use a wireless USB RF receiver dongle

[Q] USB instead of wifi functionality?

I'm thinking about getting a Shield, but I've never bothered with wifi connectivity on my desktop PC. Can I still use the Shield as a USB gamepad? What about the streaming functionality?
Thanks for any answers!
Its not immediately clear *exactly* what you are asking here.
You can stream to the PC as long as you are on the same LAN, so if you connect the shield via wifi to your router and the PC has an ethernet connection to the router then that will work. Or you can use a USB-OTG adaptor in the shield with a USB ethernet adaptor to connect the shield to a router via ethernet too. If your desktop doesnt meet the requirements you can use splashtop instead of the official NVidia stuff.
The USB port on the shield though, well, its a regular android device. Its no different from plugging your phone into the PC. You can't use the shield as a USB gamepad like that. Best off just buying the wired version of the xbox controller if you want a PC gamepad, they aren't the cheapest (but they are far from the most expensive) but they are reasonably good quality and well supported
Just as a side note regarding Ethernet over OTG cable. Some apps (like the Play Store) won't connect unless you are using WiFi or mobile connection.
It's not the Shield's fault, just the app when it enumerates the network connectivity.
So far I only found the Play Store to ignore the network connection over Ethernet, same is true on all the devices I tested so far: TrimSlice (Tegra 2), TF201 (Tegra 3), My Touch 4G, Samsung Galaxy SIII and the Shield.
The Trimslice is the only one with a dedicated hardware Ethernet over PCIe, the others I used an OTG cable and hooked a USB HUB with Ethernet built in.
I don't stream PC games but when Nvidia was demoing the Shield's streaming capabilities they were using an Ethernet dongle so they didn't have to fight for WiFi connections from the attendees at the conferences they were presenting at.
To clarify, I was hoping I could simply plug in a Shield to my USB port and use it as a USB gamepad, but by the sounds of it that doesn't seem very likely.
Can't you just connect ps3 controllers to it over bluetooth? If you can't do that yet I'm sure you will be able to

No, you cannot unfortunately. If that is what you require, buy a wired xbox controller.
When you set a device to USB tether, it adds another USB profile that creates a network connection over the USB - with some hacking it might be possible to use this connection. I think adb can also do some kind of port-forwarding to allow communication between the device and the computer.
It might be possible to get something working, both for controller input and streaming, but not sure how difficult this would be or what the performance would be.
But I don't think any of this will work very easily out of the box unfortunately!

Unstable connection with Xbox 360 wireless controller

I'm trying to get my Xbox 360 wireless controller and wireless receiver (Chinese knockoff that works perfect on PC) I had laying around to work with my OPO. Sadly this has been harder then I expected. I have ran into the following problem. After I reboot my phone and the receiver is connected through a OTG USB cable, my controller is connected to my OPO and I can move in menus and play a SNES game for example. The problem however is that this connection remains for a very short amount of time, it seems that the phone stops seeing the USB device that is connected. When trying other USB devices this problem does not occur, I tried a USB stick and a USB mouse. Once the connection is lost the only way to regain connection is to reboot the phone.
I have no idea why this is happening
I've tried many settings and tested a lot of stuff:
I followed the steps in this thread: http://forum.xda-developers.com/showthread.php?t=1792531
I also messed around with other product ID settings related to xbox 360 controllers: http://www.linux-usb.org/usb.ids
On my Windows 7 PC I used USBview.exe to see with which ID the receiver/controller combination was identified which was: 045e 0291 (Microsoft Xbox 360 Wireless Receiver for Windows)
I used the app USB Device Info to see if my OPO was detecting anything via the OTG cable. As mentioned above after a few seconds ~ < 1min it just disappears.
I've searched in general with Google and specifically on XDA and the OPO forums but I've not found a similar problem with regards to the disconnection problem.
Anyway, if someone here has experience with wireless xbox 360 controller on the OPO or USB devices that disappear. Help would be appreciated!
I think I might have found why this will not work correctly, the default kernel of the OPO doesn't have xpad.ko.

The problem is that there are no drivers for the Xbox 360 control pad.
You need xpad.ko for the controller to work and ff-memless.ko for the vibrators.
Unfortunately these have to be built for the kernel you are running and as far as I know nobody has built any for the nexus 5 yet

This OPO kernel has xpad.ko included, I might check it out and see what happens.

USB Power Always on / Ability to tun on device with USB

I was wondering if anyone could help me, I have a Probox2 EX+, It comes with the Wireless USB 2.4Ghz Remote Plus, With this remote you are able to power the unit on and off. I also have a Himedia Q10, The Q10 will turn off with the remote but not back on, I assume this is due to the USB ports getting powered down when to box itself is shutdown. Is there a way to make the Q10 so the USB ports will allow powering the box on with a USB device ?
Both devices are Rooted.
Thank you kindly for any info you may be able to offer !

display and touchscreen dead, no usb debugg : solution for this issue.

morning geeks
you have a phone, which is not able to :
show the display
use the touchscreen
but the hardware is still able of these features :
usb mtp device, as a usb key
wifi network
cell network
and so on..
so you are here, somebody gave you a smartphone, running android, locked, but you can't neither see display or use touchscreen;
but its starting anyway, you can hear the ringer if you call on it;
how would you do, without usb debugging enabled, to use this electronic technology as a specific usage, like a wifi AP or a usb key?
in an other words, what is the method to restore it and to take the control of it?
you just have a usb mouse can be connected on it. but no display.
[this is mainly destinated to avoid throwing several android hardware to bin, cause it can still poweron.]

Wireless Controller Problem

Hello.
For the last two days I have been trying to make my OMEGA Wireless Gamepad (a copy of the PS Dual Shock controller) work on my Galaxy J7 2016 (6.0.1).
It connects to the phone through Bluetooth as a input device no problem but it won't work further than just that.
I even rooted the phone to try some stuff out but to no avail.
It stays connected but none of the buttons do anything (not in phone menu, not in PPSSPP, not in a bunch of keymapper aps).
So I was wondering is there a way to get this fixed without me having to buy an Micro USB to USB Adapter and trying that out.
Thanks for reading.
