and how is it different from MTP?
usb host on the go.
Means you can use an adapter to plugin controlpad/keyboard/etc..
-m
It has nothing to do with MTP.
Basically allows you use flash drives, mouses, keyboards on your phone with an adapter. Probably... microUSB to full-size USB.
USB On-The-Go, often abbreviated USB OTG, is a specification that allows USB devices such as digital audio players or mobile phones to act as a host allowing a USB flash drive, mouse, or keyboard to be attached.

oh... that's it? With all the ranting I read about the phone not supporting usb otg I was thinking it was something more important like not being able to transfer files easily.
Why would you want to hook up a keyboard to a phone?

Who knows? lol. the flash drive could come in handy though. It'd be expandable storage OR! if you have a ASUS transformer, you can hook the transformer dock with the Galaxy Nexus and you'd have a portable charger with you that can transform into a netbook or a tablet or just into a charging station
so, I could hook up a USB hub and connect a mouse and keyboard (USB screen ;-)?

One reason would be so you could type on it without using the on-screen keyboard. I have a bluetooth keyboard that I use with mine sometimes. If I added a bluetooth or USB mouse and MHL adapter to a monitor or TV, I'd basically have a complete usable computer.
In some cases it might be very useful, in others it might be more trouble than it's worth. Some people might like it, others might think it's stupid. Regardless of any of that, I think it's pretty cool that it can be done and that the lines between phone/tablet/laptop/desktop are becoming very blurry these days
Hello all. I was wondering if I were to install a A500 rom on my A100, would I be able to use a XBOX 360 controller on it? Of course I would need an adapter. Does anyone know this?
we still do not have a usb host enabled kernal so not at this time
Thanks for the reply. So is it technically possible once there is a usb host enabled kernel?
I really hope so.
From what little i know of USB host mode I beleave it is possible in ICS devices with usb game controllers

I don't think anyone knows for sure. I believe I read somewhere that the Hardware (on the board internally) was not wired to support it. If that is the case nothing done to the Kernel will enable it without opening up the device and performing a hardware mod. I could have been reading this about another device but I'm pretty sure it was the A100.
Bottom line is we will just have to wait and see.
I know for sure. No matter how it is rooted, no matter the kernal, no matter the ROM, adapter or not,it will not work. The USB port in the Acer A100 is not powered. It is set to be connected to something with power. Not to provide it. In order to connect a game controller USB to a device the USB port powers the controller. So it is a hardware issue, no ROM or Kernal can fix it.
Well, I assumed that you are talk about the wireless ones and thus, here is my info for you: Xbox 360 Controller are not Bluetooth, but both the PS3 and Wii controllers are and have apps to support them for Android.
Good luck with it, I'm off to try a Wiimote on my A100.

Power is one problem, but I think the bigger issue is that the port simply doesn't have a hosting mode. (Correct me if I'm wrong!) If it was simply power you should be able to run an external powered hub and get devices to work.
But I know that there's an internal USB bus on the board (courtesy of the NVIDIA chipset I think) that's being used for some components, e.g. the GPS (dmesg shows the kernel loading the pl2303 serial driver and hooking it up on USB.) That would mean to me there's a possibility of tapping into the board to hook into the USB bus, but that's beyond my skill level. A macro model of the motherboard in the service manual does show USB hosting available on the NVIDIA chip.
To the original topic: XBox 360 controllers require a relative lot of amperage to run; it probably wouldn't work on a little device like Acer even if it did power its port. (We could expect something in the ballpark of 250ma max in this mythical setup.) Bluetooth does work and works great; I have an iControlPad which works well and is a blast.

As for the 360 controller power, using a wireless unit with the charger cable allows it to be used as a USB version controller, this should alleviate the power requirements for the controller to 0, while allowing it be used as a wired controller. But again, we need USB host, which we don't seem to have yet, or ever. Or a wired controller with a powered hub, but only if it offers protection from the host port being charged, I seriously doubt the tab itself can protect itself from this as it was never meant to have something like that on it, and may just take whatever voltage goes into it. Same issue I've seen on another tab..maybe the nook, maybe the kindle, I've had both and I forget which is which sometimes.
Then again, the wireless with the USB attachment may try to draw power (as it is the charger) and work opposite of how I think, and of course not work as it'll try to draw power through the port for charging.
Hi folks,
As I understand it, the Glide supports both HDMI out and USB On the Go. What I'd like to do is set up my phone to be a basic laptop.
The first part of my plan is to get the right cables. Does anyone know of a combo cable that provides both HDMI female and USB A female to the phone so I can hook one end up to a powered hub with an ethernet dongle and keyboard/mouse thing, and at the same time hook up an external display? Also, if I do this, I assume the hub will need to provide power in some way back to the phone. Is that correct?
Or is this going to be so expensive I should just use a cheap computer?
Thanks.
Jonathan

Assuming a computer on site, you could always vnc.
From past experience with other PDA's, you will -quickly- grow tired of this and end up purchasing a laptop anyways.
Not that you'd want to be internet'ting, much, on a TV, either. For anything short of a quick search, weather, TV guide, you're going to want to cross the room to your laptop, IMO.
Which is probably what you'd have your HDMI connected up to, anyways. Although using the Glide as a remote in that situation is probably attractive. Or as an XBMC control sort of thing, but, again, likely the content would come off the computer rather than the glide, the glide just remotely controlling it.
You can easily test how you find this, either by using a bluetooth keyboard and playing (never mind the external screen for the moment), or by vnc'ing to it from a computer (pretend it's a bluetooth keyboard and it's an external monitor, for the moment).
Technically possible, not practically feasible.
Chromebook?
Just get cheap laptop. It will serve you better and will be much easier to use

HDMI out is supported by the SoC, but to the best of our knowledge those pins aren't actually connected to anything in our phones. That said, there's a protocol for outputting to an HDMI device via a USB dongle that doesn't require any hardware infrastructure beyond USB OtG, which we have.
In theory, you could get a powered USB hub (it MUST be powered, no way in hell the phone can put out enough current to support all this), plug a keyboard and mouse into it along with one of those USB-to-HDMI dongles, then hook the phone up to it as a host using an OtG cable. At that point it's just a matter of ROM/kernel support of all the peripheral hardware. (Ask dman? Nah, I'm sure he's WAY too busy.)
If you are just using it for media as like an htpc, I'd reccomend skipping all the usbotg stuff and just connecting a net book or some other cheap PC to your display.
My current setup: old netbook with 1tb external hooked into TV, controlled by the glide (unified remote app) and the external drive is also network shared so my glide (and tablet) can read from it.
Its served me well for playing all of my local video files as well as flash video and light browsing. Depends what you're using it for though, I suppose.
The only time I've ever really used HDMI out with android is to play n64 emulators (or other games that support a bt controller) or if my girlfriend is watching desperate housewives or something on the main setup. It works well enough for that, but not enough that I would make a habit of it.
There doesn't seem to be much documentation on the USB port on the Fire TV, and I have a couple of questions regarding it.
1. The port seems to be powered, as I have seen people talk about stand alone drives. Is there anywhere that documents the actual power output in amps and volts? Is it the same as a standard USB port on a computer? I'd like to connect a splitter with a 1TB WD drive and a wireless mouse/keyboard combination, but I don't really want to buy a powered hub.
2. Is there a proper shutdown procedure for the USB port so as not to fry it? I had a motherboard go bad on a computer many years ago because I would remove a wireless mouse without properly disconnecting it. I would hate to do that to the only port on this piece of equipment.
Thanks
I'm not able to get to the bootloader screen because the front usb port is not functioning on my unit. Has anyone been able to use one of the USB ports on the back to get to ADB and/or get to the bootloader? Is this a known issue with a workaround? I've done quite a bit of searching and have not turned up any solutions. Considering what is involved in shipping this back, I'd much rather figure something out. Thanks in advance for any help!
Edit: I should mention that I have used the adbon password and it does acknowledge that adb has been enabled. Just nothing seems to work on the front port. When I connect my Linux machine and run lsusb nothing shows for the unit. I have considered buying or making a USB-A to USB-A cable to connect my computer to one of the back USB ports, but I'm concerned about how these back USB ports are designed. Is it as simple as a built-in OTG cable? If so I'm probably fine. If it is more like a computer's USB port I could damage my laptop, my headunit, or both. I'd really like to hear if anyone else has had to deal with this. Unfortunately I haven't verified if the front USB will charge a phone. This is my next step.

My front USB also doesn't work. I even got mini to standard USB cable with unit, but plugging flash drive into it doesn't produce any reslt.
I also plugged extension cable to one of back USB ports and tried it (plugibg same USB flash) but it doesn't work either.
So I'm also confused.
Does that mean you are still running the stock ROM? I have been hesitant to install the custom ROM because they say you must be able to get into the bootloader even though I couldn't find a step in the process that required it.
Regarding the USB ports not working at all, you may find that you need to use a powered USB hub. I've seen reports of USB devices acting up due to the low power. This is one of the reasons I thought it might be safe to use the rear ports with my computer. (My first real test is going to be mangling a male-to-male USB cable so only the data lines are connected to see if I can get those rear USB ports to talk to the computer. I figure that way there is no chance of frying any circuits.. Each side already has its own power and I don't believe any signaling is sent via the power pins.)
On my unit (MTCB-KGL-V2.80), I have used a T-Mobile USB broadband modem successfully on the rear port, so I know rear ports are live. I did take it apart to see if something was obviously wrong with the front port, but nothing jumped out at me.
So I have a bit more information on my headunit. BTW, I have the BMW E46 model with MCU MTCB-KGL-V2.80.
On my system, both the front USB port and the rear 3G USB port are wired as device ports connected to an AU6258 USB controller (http://www.sunnyqi.com/upLoad/product/month_1403/201403162331285643.pdf). I don't remember exactly which USB ports they are connected to, but I believe the 3G port is connected to port 2 (pins 6 & 7) and the front USB port is connected to either ports 3 or 4 (pins 9 & 10 or 11 & 12 respectively). Nothing is connected to port 1 or to the upstream port. The other rear USB port is wired directly to the MTC_RK3188 board.
All three ports are wired with only four pins, so I'm concerned that none of them could work with the computer. The USB controller doesn't have USB ID pins, so does that mean that the 4 downstream ports are OTG and the upstream port is for a computer? Unfortunately I don't know the hardware side.

No I flashed Malaysk ROM from GPS SD card. No problems. Just follow instruction. I had luck that I didn't need to recover from USB.
Did you tried with USB powered hub? I don't have one to try it myself.

plugging and unplugging all three USB cables and the number did not change. BTW where did you use the "adbon" command? The only place that I could even try was at Settings > Factory Settings. Regards Flint
