Can a kernel for USb On-The-Go be ported for x10?
depending on the kernel
I really doubt it, I think it is kernel dependent. Also where you gonna get the cable? :S
I have the USB power hub to a micro usb connector...

Hi,
I hear that the usb chip in galaxy s supports otg. Is that how sound is implemented in the galaxy docks? I heard sound goes out via usb and one has to switch it via some android app. So is the galaxy dock housing a usb sound card? Could someone with a dock check what the dmesg messages are?
I'd like to play with OTG support, and it would be easier if the dock already does it. Does USB OTG allow charging(maybe with a custom usb cable, assuming usb gadgets get their power from usb hub)?
I alsowander weather. That is possible

Don't understand why nobody is interested in this.

Still no luck.so sad
Stupid question for anyone who might know. If I use the webtop over HDMI hack, and I use the USB OTG hack being discussed in the overclock thread (use a micro B to USB A adapter and a powered hub) would it charge the phone or not? I assume no but if not then I assume Motorola did something in their docks to allow this. Would it be possible to do this with a USB hub? I could open it and solder wires etc I just don't have an atrix yet to try it.
hum....looks like if I have pin 5 at 36.5 kOhms it will allow charging and host mode, but I may have to open the adapter, put the resistor, close adapter, open hub, solder the + and - wires from one of the slave ports to the master port to provide the 5v. Does that make sense to anyone? I am not an expert on USB (I am a solder tech and avionics tech though) but it sounds like it may work electrically.
Never mind I found my answer here:

I want to have S2 with usb keyboard, mouse, (probably a pendrive/hdd also), and a hdmi screen connected while charging the battery. My question is, what cables/adapter and usb hubs would I need to achieve the desired configuration?
As far as I know, what you want isn't possible. The MHL/HDMI and USB are mutually exclusive -- they share a connector, and when the MHL/HDMI adapter is plugged in, the connector switches into MHL mode, and the USB data pins are re-purposed.
you can't, maybe a bluetooth mouse/keyboard will solve part of the problem. And maybe you can use a powered hub to use them together, but not with HDMI
The phone differentiate MHL, USB,USB jig, and charging mode (AC vs dc) via resistance between two of the connector pins on the cable. So one mode at a time.

Hi,
Having just tried female to female usb connected to the oem usb cable by samsung, was hoping it will be able to connect and detect a flash or external drive but it did not.
So the question is this, since a usb is universal, would it be because of the oem cable or missing support from the kernel?
Even if power is supplied through, nothing was detected but power and it started to charge.

Good to see that, as it should be handled by the o/s...
USB Host mode?
Seen a youtube video introduced a special usb dongle as an accessory which turns the microusb port into usb host mode and it will allow keyboard and various other devices to be connected.
Seems like it is not a usb host port on its own.
You need a USB cable that supports OTG. You can get one for a few bucks from Amazon. The kernel already supports attaching all kinds of USB devices, so just make sure you have the right cable.
Hello,
Does someone know how archos managed to block certain devices from the 3G usb port? I am studying the kernel source codes and the filesystems of several roms and a cannot find any references to some blocked devices. (Yes I am a expeienced C(++)/linux developer) Most devices do work on the OTG port.
Memory sticks seem to work but when i plugin a mouse of keyboard the folowing line appears in dmesg:
hub 1-0:1.0: Cannot enable port 1. Maybe the USB cable is bad?
What is different on the 3G Usb port?

Good question. I'm not a developer but I have had that happen on a few (older) USB drives as well. Surely it couldn't be and old usb1.0 standard or anything that isnt enabled?
I just figured that it was a power issue thumb drives use almost no power, I'm thinking that archos designed the 3g stick/port to provide power on the low end of USB spec 5v DC and 0.5-0.9 amps.
I'm just going to link to my other post HERE about a powered USB hub. has anyone use a external battery to charge tab and do you get fast or slow charge?
