I don't have an usb dac card, so I can't really comment or test this. Here is apage for Nexus One users how they can use an external audio card: http://sven.killig.de/android/N1/2.2/usb_host/ It is a very-very basic support though.
OP. I have the same question too. I have been trying to figure out a way to connect to USB DAC(like Fiio E7) to my galaxy s & S2. Can we expect this from you ?
Check the previous post. Unfortunately due to hardware and software limitations of the OTG controller in the SGS and SGS2, it might not work. Besides as I don't have an usb audio card, I can't actually test / develop for it.
You will need to modify the kernel to include the usb host functionality. (HD2 uses the same chip as the N1, and Desire) After that it should work.
cant download it from market error message "unknown error code during application installation - "110" "
while i tried to do it manually it say "application not installed"

my phone is a samsung galaxy 3.
it has this proccessor- http://www.samsung.com/global/business/semiconductor/productInfo.do?fmly_id=835&partnum=S5P6440
(ours is actualy s5p6442 but both are very similar if not the same) it says it has a on-chip usb otg controller but no mention oh usb host....
will we be able to use otg? (like pendrives ect.) ?

Thanks. Doesn't look like it will work. I'll post if I get my USB DAC to work with the GNex
Enable USB audio
There's a lot of people asking for enabling USB audio ie connect to a DAC or car system. Check issue at code.google.com/p/android/issues/detail?id=24614 Maybe you could get some help there.
Also please upvote the Issue so it might get some attention.

Does anyone know if this would work on a Droid X or perhaps Kindle Fire? I have a OTG cable on the way soon to test for myself, but it's coming from China so it could be awhile and just wondering what to expect.
P.S I also have a Fiio E7 and would absolutely LOVE to see USB audio support in the future!

Usability on Samsung Galaxy Note
I have Galaxy Note and OTG cable. Using cable I can see contents of pen drives etc without additionally installing this application. I've external hard disk (1 terra byte cap. having fat32 partition), but it is not detected.
Whether this additional application benefits me?

hey guys jus downloaded and installed on my EVO 3D after clicking on open it jus says please wait...
stuck there for more then 10mins

i think we have to ask Tytung (The Kernel Developer for HD2), maybe he can make a patch....

48Usb Host Controller
Shows enumerated usb devices, and allows you to mount external mass storage devices to the filesystem. Supports advanced features like the ability to reload partition tables and reseting USB devices. It can also control the USB Host functionality of S5PC210 devices with the appropriate kernel patch (more about this later)
The application does not use the USB Host API, so it can also run on older, 2.x devices. Because of that however almost all functionality (except for the listing of USB devices) requires root access.
The application needs a device that has USB Host (or USB OTG) functionality. Most modern high-end devices have this ability. Check the documentation and specification of your device (this functionality is usually called USB OTG or USB Host)
If your device doesn't have native USB OTG functionality, there are kernel patches for some older devices to enable the functionality, most notably for:
- S5PC210 based Samsung phones (Galaxy S, Captivate, Nexus S)
- QSD8250 based HTC phones (G1, Nexus One, Desire, Incredible)
You can find appropriate kernel drivers for these phones here:
- Samsung phones: http://xdaforums.com/showthread.php?t=1450298
- HTC phones: http://sven.killig.de/android/N1/2.2/usb_host/
Note that these drivers might require skills to install, and may damage your phone and void your warranty!11Changelog and downloads
The application can always be downloaded from the Android Market: https://market.android.com/details?id=hu.sztupy.android.usbhostcontroller If you have Market, please download it from there. Thanks.

4Help/FAQ
What is this good for?
Usb Host Controller let's you see what devices are connected to your phone, and also lets you mount external drives.
There are already a lot of apps for that
Yes, but UHC has some distinctive features:
- To enumerate devices it does not use neither the USB Host API, nor external applications, like lsusb from busybox. Instead it reads the information from the filesystem, which is always avialable, therefore it can be used to debug all kinds of devices which have USB host support.
- It has a special features to help control the USB Host mode of S5PC210 based Samsung devices (Galaxy S, Nexus S, etc.)
- It also has some features usually not available (even from the command line), like the ability to reload the partition information, and the ability to reset USB devices
How to use
Most of the functionality should be straightforward, but the USB tab might need some clarification:
The USB tab shows all the USB devices connected to your phone, that have been found by the system. Below the devices you can see all of the USB Mass Storage devices (external hard drives, flash drives, other Android phones, etc.), with their avialable partitions. You can click on any line, and based on the line you click on you will have a list of options to choose from:
- Clicking on an USB device in the upper part lets you reset that device. Sometimes mice, and keyboards need to be reset for them to work correctly.
- Clicking on a partition lets you mount it to a mount point. The application will ask you where you want to mount it. The list of mount points can be set inside the settings panel. If the partition is mounted you can unmount it here.
- Clicking on a Mass Storage Device (not on the partitions, but the base device above tha partitions) will lets you reset the hard drive, or reload the partition table of the disk. The latter is useful, if the system doesn't recognize a change in its partition information. This is usually needed, if you connect an external card reader, and you insert or remove a card from it. It also makes conecting other Android phones as storage possible, as they will not send their partition tables until you switch the USB Storage mode on them on.
What are the options if I have an S5PC210 based phone
The application lets you change how the USB Host is working in the S5PC210 based kernels (and currently only on those!). The avialable modes are:
- Client: Default mode, means no matter what happens the phone stays in client (USB gadget) mode
- Host: No matter what happens, the phone switches to host mode and stays there. Not recommended.
- OTG: The phone is in client mode by default but changes to host mode if an OTG cable is detected.
- Auto-host: The phone is in client mode by default but changes to host mode if any type of cable is detected. (good for homemade OTG cables where pins 4-5 are not shorted)
Using Host mode is not recommended, as the root hub of the S3C Host driver won't re-enumerate devices if they are changed (It is still useful for debug purposes). If you need host mode use either OTG mode (preferred if you have a valid OTG cable, which means it has the 4th pin grounded), or auto-host mode, which you should use if you have a "non valid" OTG cable (on which the 4th pin is not connected)2
If the device has USB host mode (most newer high-end devices and tablets, from that even most chinese ones), this app should work on it just fine.
If it doesn't have, but the chip supports it then a willing developer needs to try to enable it. I'm only working on S5PC210 (Hummingbird) based phones, as I have only access to them. Patches for QSD8250 (Snapdragon) based phones are available though.
If the device has a chip without USB host support (most low-end / mid-range phones) then sorry, this is not possible.1
S3c driver only visible if you have an s3c otg controller (samsung phones). Please post a dmesg log (after connecting the device) if you can, i'll check it
