Help cant get usb host working - Nook HD, HD+ Q&A, Help & Troubleshooting

Hi for some reason i cant get usb host to work,
But the thing is that my devices are being powered but not detected on Android.
Also i have a "7 Nook HD with Cyanogen Mod 11 so it should work right?.

Did you enable USBHost (using Verygreen's USB Host Switcher app linked at his CM10.1 thread's OP http://forum.xda-developers.com/showpost.php?p=41024398&postcount=1)?

Yes i used that and a whole bunch of different apps and roms but they wont work.
Also the app on the screen is the USBHost Switcher App.
Edit:
i also used the nook color with cm7 and usb host worked.

Ok this morning i tried connecting my usb device again and when i pressed the button to enable usb host it worked and
i was able to use my usb device then it said it disconnected because i had another app for usb host that does that.
also could it be my cord?.

I never could get my nookhd to recognize usb either.
I am running verygreen's kernel 3.0.31 -hummingbird-green+ jun 13 2013
cyanogen 10.1
i have usb storage in storage menu as well as apps that can mount devices and storage. I also have the usbhostswitcher app as well as another one I found on here that helps for this.
I have the female to female adapter...yet no signs of it working whether I connect a mouse, usb flash drive, etc. I bought the adapter from the ebay link from verygreen post and ordered another one from diff seller today just in case...
Any thing I need besides the apps? Also anyone get a usb - to - ethernet adapter to work for this nook?
thank you all for any input

HOST USB or USB HDMI Video Card ? Any way to use usb port to use usb devices ?

Usb port is it locked or there is possibility to use it like usb host ?
To manage copy pictures of a camera to phone without pc by usb adaptator.
Samsung talked about usb 2 hdmi cable and think if its real it use some usb video card supported by phone(because of physic material imcompatibily of hdmi nd usb)
May there is a way to dev a tool or hack to get it works...
Aah!! Finally somebody like minded!!
I had been scouring forums for something like this. USB OTG would be an excellent add on to this phone. If not OTG, at least host would be an excellent idea.
No idea whether the existing USB Host driver for Nexus one would work on this one.
The processor on SGS already supports USB Host (not sure about OTG though). This has been pointed out in their press release - w w w .samsung.com/global/business/semiconductor/newsView.do?news_id=1043
I am just wondering - should we request Samsung themselves via mass petition to open up this feature on SGS?
some USB devices might be compatible, like the 100/1000 Mbps USB to RJ45 plugs
those same ones works in Windows Mobile it should work as well for Android, however a driver will be required.
mouse and keyboard support should work out of the box
external USB keys for storage, or even USB mass storage devices should work out of the box as well.
usb audio... hmm... not sure what else at the moment
Hi AllGamer
Thanks for the reply. So how exactly do we get this going on SGS?
I am much more interested in having USB HDD support on SGS (hopefully without an ext power source - am I asking for too much? ).
Are you suggesting that the N1 fix should work here also? Can somebody help us with a "How To" to enable this on SGS?
Cheers!!

you can plug in any USB mass storage devices (USB hard drives) and it should work.
However, you might not get enough power from the usb port, you'll still need need power cord for your external usb hard drive.
I know on my HTC windows phones works like that, it should be the same for Android.
I'll try that when i get a chance.
you just a need a USB female to a mini USB male cable
yep!! you are right about power!!! I am trying to get a cable - hopefully in couple of weeks should have this.
but I am wondering if all this would work without proper drivers in it. Would SGS have USB HDD drivers in it already?

I can see one problem, You will only be able to use Fat32 drives unless someone compiles NTFS / HFS+ into the kernel. Ext3/4 is already done so I don't see many problems. What I recommend you do is get some sort of adaptor for Female USB > Micro USB and test it out with a flash stick or you can hack one .
Yeah - I understand the difficulties of having NTFS support outside the MS world.
I didnt know that ext3/4 were already a part of the kernel!! Is this by default available in all Android kernels?
For USB Host cable - I am guessing that this one can be used - http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=250671106072 (same as what Sven used for N1 USB Host capabilities).
But I seriously doubt plug and play would work (that would be too much of an expectation! )
Does any body have that cable here, who can check out if SGS does actually work in USB Host/OTG mode?
Sven has try with a Galaxy another Host Driver

Hm what can we do with these files?
However, any news about this?
Maybe, we could ask some Galaxy S kernel developers about this.

[Q] USB host mode no worky

Bought a Nook Color (blue dot). Rooted and installed CM7 7.1.0-encore. Kernel is 2.6.32.9. Downloaded Nook Tweaks. Followed Moshe's instructions for connecting USB devices to the Nook. Using a powered USB hub. I also have the male/female adapter that verygreen referenced in his thread. Downloaded Root Explorer. No dice.
The Nook does not recognize any USB device. Please tell me what I did wrong or need to do differently. Thank you!!!
Anyone? Please?
USB host aside, the (micro)USB port puts out very little power. For most micro types, the nominal power output is 100mA, which isn't enough to power most USB devices, including most flash keys.
Self-powered USB devices will work. I had some 1st-gen iPod Shuffle that worked, since they're battery powered. Also an unpowered cardreader. I imagine that devices connected to a powered USB hub should also work, although I didn't test that firsthand.
Thank you. From what I've been able to glean, a powered USB hub will allow non-selfpowered devices to be accessed/mounted by the NC. But I can plug in any USB device and it never gets ANY acknowledgement by the NC.
I read somewhere that an app may be interfering with the USB host mode.
Should I attempt to wipe downloaded apps off of the Nook? Should I just try a full wipe/format/reinstall?
Any insight would be appreciated. I've tried to find anything that I missed. But I'm running out of ideas.
From what I've read, success rate with powered hub is itself spotty. It's kind of hit-and-miss.
First thing is try w/o the hub to remove it from the equation. The techsupp mantra for troubleshooting is to minimize your configuration. Your variables are then the Nook itself, your software OS config, the cable, and the device.
Assuming the first two are OK, then find an eligible low-powered device like certain card readers, or a keyboard, or a self-powered device (some MP3 players with USB mass storage), or a HDD powered by a Y-cable connected to a laptop. Second, find a different micro-USB cable if none of the above work. Last, find somebody close by with a CM7 Nook to compare if all else fails.
Once you have at least a known-good setup, then expand from there by trying new periphs, like powered (or non-powered) hubs, et al.
I'll assume the obvious that you've enabled Host Mode in Nook Tweaks, check your /mnt/usbdisk, only FAT16/32 format and no NTFS, no multiple partitions, etc.
Good luck. If all else fails, you can wait for the CM9 with built-in host mode and see if that works better.
Can you specify what exactly you did? which hub?
Which usb devices you tried? and please provide logs

How is the USB OTG supposed to work?

I downloaded Nook Tweeks, enabled USB host mode and External vBus, but nothing happens when I connect a USB-stick via a micro ubs to usb converter.
Am I supposed to do something else? Or does the USB-stick have to be in some special format?

I got the same exact problem. It didn't seem to work at all.I think I'll have to order the adapter to see if the problem is the OTG cable or not

I ordered some cheap ones from DX, but since there are two of them and none of them works I'm assuming it's the Nook the problem is with.

It could be the USB-sticks are trying to draw too much power. The Nook host port will only supply low power USB devices (<100mA) and it is also best to have a fairly well charged battery. Some sticks work and others don't.
If you have a powered USB hub then this supplies the power so there is no problem. So try with a powered hub to at least see if that is the issue.

I used the same USB in this chart Nook Color USB HOST Device Compatibility List Sandisk Cruzer 8GB on CM7
I bought the Nook Color is to connect it to my camera via DSLRcontroller but so far still not successfully with USB stick.
Read my thread , it should answer most if not all your questions

I'm hoping to get some free time and update it this weekend with more info and probably a widget
I could never get usb host working on cm7. I have been trying to use RYC usb to control my Nikon Dslr . Once i switch over to CM9 beta it worked first time.

CM7 also shouldn't give you any trouble , as long as its FAT32 and you are using a hub
can you explain what exactly have you tried and provide logs?
I didnt use usb hub,just enable the usb host mode in Nook Tweak app and plug my usb via otg cable.

Then you didn't read good enough the thread or the chart..
You need an external hub ( powered or non-powered ) to work with the sandisk cruzer.
Thanks a lot, i ll order one and try it out.
I tried to connect with my camera but nothing happened,I guess I have to try with usb hub as well

Unpowered Hub

Don't know if this anything new but I am using an unpowered hub with Nook Tweaks to access my 8meg memory stick and play back movies. It is an old GE USB hub, has a port for power but seems to work fine for reading sticks without it. http://www.amazon.com/GE-HO97958-4-PORT-USB-SLIM/dp/B00ARNHQLQ/ref=sr_1_3?ie=UTF8&qid=1357246056&sr=8-3&keywords=GE+HO97958

CM7 only. USB host not yet working in CM10 JB.
Correct, forgot to mention that. But for an under $12.00 accessory it is a great addition. Still not able to charge and use the keyboard and mouse yet though.

Did you select "USB host plus VBus" in nook tweaks and reboot?
When you check USB Host mode and check External VBus it no longer accepts input from the keyboard or mouse. If you do so and reboot it returns to the default of USB Host mode and External VBus both unchecked or off. If you then check USB Host mode and do not check External VBus input again works.

USB Camera

I've bought an usb endoscope type of camera that I connect to both my laptop and to my samsung galaxy s5 via a usb otg cable. The app I use for the camera is the camerfi from google play and it works great. I tried to connect it to the nook hd+ via a female usb coupler but it won't work. Any ideas how to get this working?
I believe the USB Host feature is available only on CM10 and CM11 ROMs (and only for certain USB device types).
What ROM are you using?
I got 2 nooks, one on the latest lollipop cm12.1 and the other on cm11 M12.
CM12.1 current builds do not support USB Host.
On CM11 you need to use verygreen's UsbHostSwitcher app to enable it, although it does not look like USB camera is supported -- see http://forum.xda-developers.com/showpost.php?p=43053751&postcount=29.
Thanks for the info digimax. The usbhostswitcher app doesn't install on the cm12.1 but does on cm11. When I switched it on, while the camera wasn't working as you've predicted, the led light of the endoscope camera did turn on. Maybe someday there will be a fix to this, one can only hope.
