I have had intermittent success connecting the IOIO board to the Nook Simple Touch.
* It seems to work sometimes and not others
* I've tried this with beta5 root kernel and with the beta5 root kernel with the USB Host mode patch from evergreen.
* It requires that the Auto mount of the USB is turned off and the developer adb debugging is enabled.
The easiest way to test the IOIO board is with an app called "blink" which if successfull, loads a program onto the IOIO board from the Nook that makes the LED blink.
I mention this because the USB Host mode satisfies some needs, but the IOIO opens up options for several concurrent UART connectsion to the Nook, while simultaneously charging the Nook.
Has anyone had any experience with the IOIO and the Nook?

To all Devs,
May we request to have USB host enable kernel please?
Thanks.
It's not a software issue. HD2 doesn't support USB Host .

Actually it looks like lack of USB host is a software issue. I read in the Linux development thread that USB host is enabled in the HD2 Ubuntu rom..... What I dont know is whether android in its current state supports USB host. Did I read somewhere that USB host is a feature in the upcoming Android 2.3? I am not sure.
HD2 does support usb host. There are kernels in autobuild system that have usb host enabled.
Once the software is setup, (i know only ubuntu) you need to inject power between hd2 and the hardware you want to connect, because our tiny battery can't handdle the 500ma/5V power output needed for most usb hardware.
Search on ubuntu hd2 wiki, you'll find schematics for power injection cable, and people that have succesfully connected keyboards, mouses, and mass storages.

It's not that it cannot handle the power consumption on its microUSB port, it's because there is no way that it can provide power at all (it is not wired to do that), and that's why you have to provide power for all of your USB gadgets with the Y cable, for which you can find the schematics on the htc-linux wiki.
can this be possible?
Theoretically, HD2 should provide power to USB if is switched to OTG. PMIC that HD2 using it (PM7540) is able to do that.
Hi Folks
I've been playing around with a 101 Gen9 and in particular the Full Size USB Slot on the back.
On the Archos WebSite in the FAQ they state:
What can I plug in the USB port on the back of the tablet?
The USB host port on the back of your G9 tablet is reserved for only the ARCHOS G9 3G Stick. You will not be able to plug any other USB devices in this port.

I have been doing some of my own testing on this port and found that not to be the case
Every device I plugged into it has worked in one way or another (very much another in some cases)
1. The tablet has been rooted using letma's method.
2. You need to turn on the "3G Stick" in the Wireless Settings
3. The tablet Was Plugged In
On point 3. I have no idea how the battery was doing. especially with some of the more power hungry usb devices.
Here's a list of what I've tested
Not Working:
Keyboard (USB 1.1)
Working:
Kingston Data Traveller II+ (USB 2.0) - Picked up as external storage
HTC Hero Mass Storage
HTC Debug Bridge (Required Root for adb)
HTC Sensation Mass Storage
HTC Sensation Debug Bridge (Required Root for adb)
4 Port HUB (USB 2.0)
A Couple of observations.
After turning the 3G Stick on I restarted the device
I had to plug the USB devices while the tablet was starting for it to be picked up.
The Keyboard worked when plugged into the 4 Port USB Hub. I think the keyboard will function on its own with the right kernel modules
No Device showed up as The "External Storage" in the "Files" program when plugged into the Hub, even though I mounted the device (/dev/block/sd*) from terminal emulator to the /mnt/ext_storage folder.I suspect it is looking for a specific USB device number as the external storage device.
I suppose it would be good if some other people to test what USB devices they have to hand to see what works, maybe we could build a list of functioning devices. I'm going to investigate getting the Keyboard going on it's own, which is what sparked this off and also test some external hard drives with various file systems.
I hope someone finds this helpful

For me the usb stick and hard drive is working on the stock archos firmware without reboot!
I'm looking for the new instructions for this thread : http://forum.xda-developers.com/showthread.php?t=1105497
I can't find any of the downloads as the links lead to a 404 Error. Which means cant be found. So does anyone have these files still?
Nook Color Tweaks has a host mode toggle.
Pretty much any of the newish Roms will have USB host mode. I don't know about the webcam part (and don't have the right usb adapter to test it.

Thanks will try this, I installed the app, so should I just enable USB HOST MODE, then use this piece USB 2.0 A Female to Micro-B Male Adapter to connect my usb keyboard in? and it should process it? sorry noob here
If you are going to be able to get it to work at all you will likely need a powered hub as well.....
Hi all.
I heard that zte blade has the capability of USB HOST. Also heard it can't power the usb slave device attached to it. Instead of purchasing a usb power hub, i manually tried making a cable which has the similar function but draws power from PC usb port (don't know how far it works. I haven't been successful).
The description of the cable i made is in the picture attached below.
PLEASE SEE THE PICTURE ATTACHED.
For a device with native usb host (such as galaxy note) i guess the device USB-CABLE coupled with USB-FEMALE-TO-FEMALE-BRIDGE is enough to attach slave devices. But for the devices which cannot give power supply in USB HOST mode i assumed and tried the cable which was described in the picture.
Blade was my handset. My friend had galaxy note. I tried connecting blade as a slave to galaxy note with a NATIVE USB-OTG CABLE. But it said the slave device is high powered and needs seperate power supply. In such case i think the cable i prepared might work (if it works) replacing usb powered hub.
Ok, coming to our zte blade device. I prepared a usb female to female bridge and connected it to usb plug of usb cable. Then i connected only the data + and data - of USB PERIPHERAL DEVICE to zte blade. The VCC +5V (red) and GND (black) are supplied from a PC usb port.
And im sure i connected data+ to data+ only. And similarly (data- to data- only) , (vcc to vcc only) , (GND to GND only).
And i tested it with a usb keyboard and a memory card reader. I tested on cm7.1.0 because i heard this build has kernel supporting usb host (? Is it not?). Im unsuccessful with both tests. When i connected memory card reader the led light in the card reader turned on but i cant see any drive/folder/notification on m phone. And with usb keyboard there is not even NUM LOCK led on. Am i missing the kernel support or something. If so pls tell me what kernel should i use.
And is it the thing i prepared wont work at all.??
Please give me suggestions... Thanks.

Hi everyone,
I was developing a tablet application for controlling a circuit but now i stuck here somewhere.. there are a few options that i think about what to do after this stage. I need 2 usb ports , one for a usb serial converter (namely pl-2303) and other one is a standart flash drive. I tried to use a hub connected to an OTG cable with no luck. When i plug only one of my devices to OTG port they all work but when i plug 2 of them to hub system freeze or doesn't mount my flash drive. I tried 3 different hubs they are not working. Sometimes i made this setup running with an sd card reader instead of flash and a digitus converter instead of pl-2303. Then i though this can be an issue with the USB 1.1 - 2.0 specifications because pl-2303 is a USB 1.1 device and the rest is 2.0.
After i realize the realtek wifi module in the tablet is also mounted to a USB port i removed the module to check if i can connect one of my devices to that port. But as usual the wifi driver of the system is controlling this port , so when i try to power up the port, system checks if it can find the realtek module and when it cant detect realtek wireless module just shuts down the port back. While this happens i can see my device is connected to system for a few seconds before the driver shut it down.
So this is the all story. I just need this 2 device to work together. I am waiting for your opinions
The tablet is a ATM 7021 processor based cheap tablet.
Thanks in advance.
