[Q] Using Powered USB Speakers with Nook

Hi Everyone,
I appreciate the great work developers have been putting in exploring the hidden capabilities of Nook.
I am struggling with USB host now. Here is my situation:
I have a pair of Logitech USB speakers (Please google, Logitech audio Hub, since I am not allowed yet to post direct links).
These use external power and were originally being used with my notebook connecting via USB.
Now, since I do not use my laptop any more and use only NOOK, I am interested in using them with Nook.
I am currently running Nook with CM-7.1.0-RC1-encore. Is it possible to use these speakers? I read a thread about USB host and some people have mentioned using USB audio but I am not sure if they are using powered ones and I am concerned whether connecting a powered speaker may fry the USB port.
Any thoughts, experience, ideas would be appreciated.

Update to a recent nightly. There have been so many updates for USB there is no point in trying to troubleshoot the RC.

Sure, I will update to that. Any other directions to get the USB speakers working?

I read your post and decided to try it. I do not have the speakers you mentioned but do have a set of insignia usb powered speakers.
I turned on host mode and connected the speakers to the nook. Tried 3 different games and had the same results. The speakers will power up and receive a signal from the nook. They work for about 20-25 seconds then lose the signal from the nook . I have to reset host mode to reenable them.
At this time, I would recommend using powered speakers through the headphone jack or a headset. Not sure what's going on through host mode but it had me worried when I had to reset host mode 3 times.
I'll run a logcat to see what's going on in the system but it looks like a no-go for the present. I get excellent results from powered speakers through the headphone jack. Just a thought and I'll get back to you with the results of the logcat.

Thanks a lot Moshe5368 for your response. The problem I have is that these speakers do not have 3.5 MM input and USB connection is the only possibility.
Though they are really nice speakers, I guess if this doesn't work then its time to just order another pair of speakers.
I have just ordered the USB converter today (from Micro USB to USB-F) and have not tried it with the speakers I own yet. Will test that and revert back on what I find.
BTW, the speakers I have are powered with regular power (USB connection is just for Audio signal). Do you suggest I try them? Any chance they could fry the Nook's USB port?

It is a possibility that that type speaker would work. My logcat showed (if I read it right) that since the speakers were drawing their power from the usb port (even through the usb powered hub) I exceeded the power available through the micro USB port on the nook.
I was not sure what to expect but thought that might be the case. I have a set of powered speakers from jwin that plug into the headphone jack and perform perfectly.
Let me know what your results are.

Sure. I will keep you posted as soon my adapter arives.

[Q] Can you plug a USB mic into the Note?

Hi all,
Has anyone hooked up a USB mic to the USB port of a Note via a USB OTG cable?
I would be really interested in using a decent USB mic with Audio Evolution that just got released last week.
I'm not sure if you'd need drivers for it, or it would just register as a mic in the same way a mouse or keyboard works OK.
I tried googling but couldn't find anything, except a video in which someone hooked up a USB mic preamp, but once you start doing that you lose some of the portability of just having the Note plus a USB mic.
I've seen the iRigMicCast, but I think a USB mic might have the potential for better audio quality, and also more options if any USB mic worked.
thanks,
Rich

mouse, keyboard, pen drives and a few portable disks on fat32. that's it i guess.

Yes, you can. You need to compile kernel with your usb mic drivers and flash it to your device.

I tried to connect a couple of usb audio devices to the note (otg cable) - No luck...
Hopefully ICS will fix this.

usb audio?

Whats the best ROM for USB audio to work flawlessly. My nexus 7 needs to be nothing but the head unit of my car hooked up to my fiio e10 USB DAC which will go to the amps of my car. Usb audio isn't working yet. Link me to the best ROM and kernel to do this please?

outputs
Is there such a thing? I thought that the nexus 7 had no outputs of any kind..

You need an otg cable. The only way it works is if I reboot the tablet with the otg hooked up to my Fiio E10 USB DAC. Ifni unplug the otg then my tablet freezes every time. It does that with my USB flash drive as well. I can't even access files on my flash drive. It sees the drive but it shows no files at all.

Bump. I need usb hot plug.

USB Audio Out Works!!!!

Heads up to all the audio guys out there. Listening to music as I type through my USB DAC > tube amp setup with no special setup. Just USB OTG cable to DAC.
USB Audio Out FTMFW!!!!!
(I'm on AT&T model running ARHD 9.1, not that it matters, I'm sure this feature is universal)

USB OTG to DAC? Do you have an link or pic to such cable?

Just a regular USB OTG connected through the USB cable that comes with the DAC

I have my HTC one with headphone jack to rca cables going into my tube preamp the foreplay. Then from the foreplay to my Dynaco ST70.
YouTube videos sound like garbage bags flapping in the wind.
The tube audio only people would smash my face in if they heard what YouTube sounded like on tubes. Not a good mix at all...

Yep, just a run of the mill standard usb OTG cable and then plug the usb cable from your DAC into it and your good. You'll get the headphone symbology in the status bar and the beats logo although beats appears to be bypassed (which is good) utilizing usb audio out.

Is that version 1.29? I have a T-mobile HTC One with 1.27 and USB DAC wouldn't work with FiiO E7 or JH-3a.

4.3 Update broke the USB audio out session disconnect
I've got the Sprint variant. Loaded the OTA update to 4.3 and now my USB audio gets hung when I disconnect my OTG cable. If I try to plug it in and reconnect later, my handset locks up tighter than Fort Knox. I've tried a factory reset, took a trip to the Sprint repair center (where no one even knew the audio out function existed ) so I'm stuck rebooting my phone between every listening session. Complete PITA. Specifically purchased this phone to use with my Fiio Andes, and everything was great until 4.3.

Does this significantly effect battery life?

Le Pro3 type c audio

Because this phone will be using the usb c connection to transfer audio with, will it be able to use external dac's such as the audioquest dragonfly or the chord mojo with out the need for an app like usb audio player pro?

The whole idea with usb audio is to remove DAC from the phone, enabling best audio earphones can produce. Which DACs are supported, I don't know.

With my Pro3 i just needed one of these: goo.gl/uGYUH4
My Oppo HA2 works perfectly with it.

Does the ordinary headsets with controls on wire like answer button or volume keys work with usb 3 adapter?
