PROBLEM with 24/96 bit-rate USB DAC that worked fine until I plugged in two

I'm using a late 2008 15" Macbook Pro that I bought Jan 2009 right before the SD card models came out. Mac OSX 10.6.4 and iTunes 9.2 are installed. I have a Nuforce Icon HDP and a CEntrance DACport 24/96 bit-rate USB DAC (external sound cards) that still work great right now. Note - 16 bit/44 Khz is CD quality, and these 24/96 files are hi-resolution downloads that are closer to SACD or DVD audio.
I have been evaluating a new third 24/96 USB DAC plugged directly into the Macbook USB port (no hub) which has been working fine for over 2 weeks with 24/96 bit-rate lossless music files in iTunes. Audio Midi Setup is set for 24/96 to match the music file's resolution. After making suggestions to the manufacturer they made some improvements and sent me a new version to listen for the differences.
I listened to the new one for a day and it worked fine, but when I plugged in the original test sample into the second USB port at the same time as the new one in order to compare them, the sound became garbled and noisy. This never happened when either one was plugged in by itself. Note, if I make changes to the DAC's bit-rate in Audio Midi Setup I usually close iTunes first and then re-open it when I am done.
Upon hearing this new problem I unplugged both of the new USB DACs and plugged just one of them back in, but now it causes iTunes music playback to pause when one is plugged in and set for 24/96 in audio midi setup. Prior to plugging in both at the same time, either one worked just fine by itself. There is no reason when unplugging one or the other that they shouldn't start working again. But now I can't play any 24/96 music through either one anymore. In quicktime player the songs don't pause like with iTunes, but there is no sound coming through even with just one DAC plugged in at a time. Then I discovered that if I go into Audio Midi Setup application and lower the bit rate to 24/48 then iTunes will resume playing again and I can hear the music fine with iTunes or Quicktime player.
Basically, my Macbook Pro has now lost the ability to play 24/96 bit rate with either of these new USB DACs, when they both worked fine before I plugged them in at the same time. More confusing is that they use the same USB receiver chip as in one of the DACs that I mentioned above in the first paragraph, and both the HDP and DACport still work fine at 24/96 bit-rate. It's only these two new USB DAC that require me to lower the bit rate in Audio Midi Setup to 24/48 in order to listen through them, and this wasn't a problem as recently as yesterday!
The computer is acting like some setting needs to be wiped out - it's DEFINITELY NOT the USB DAC's that are faulty because they still both work fine at 24/96 on my wife's iMac (I'm afraid to try plugging in both at the same time to the iMac in case I screw that Mac up too).
I have reset the PRAM a few times, and this doesn't fix the problem. I thought maybe the com.apple.audiomidisetup.plist file could be corrupted and deleted it, but that didn't help. I don't know what to try next to get the Macbook to start fresh when trying to use these devices, short of having to re-install OSX.
Please, does anyone have a suggestion of how I can make the Macbook forget it ever saw these two USB DACs, and let me start fresh so they start working normally again? I do dozens of reviews for Head-fi.org and I can't afford to have my Macbook Pro compromised like this, which could prevent me from doing some reviews or evaluating new products.

UPDATE:
As noted in the first post, both of these newer USB DAC work fine at 24/96 on my wife's iMac, so it's clear that they didn't both become defective when I connected them to the Macbook Pro at the same time.
Resetting the Macbook Pro PRAM didn't help, so I removed the hard shell laptop case to get to the battery and remove it, then reset the SMC. After that I could use the original DAC at 24/96 again, but only IF it was plugged into the rear USB port. If I plugged it into the front USB port then the sound was garbled and filled with noise. This was a vast improvement over no sound at all.
Then I switched to the replacement/updated DAC, but I got no sound at all from either USB port at any bit-rate. And returning to the original DAC again now results in no sound again.
Sigh... I will reset the PRAM and SMC again, and see how far I can get with this. I'd still love some help. Thanks!

Multiple Audio out: usb dac audio out and hdmi out

Good afternoon everyone, I have a 2010 mac mini with the following audio set up.
- A usb dac (xtreamer) connected to my stereo amplifier
- an Hdmi cable to the tv to get video and audio diretcly to the tv
Is it possibile by any chance to get simoultanesly audio output both from usb audio out and hdmi audio out???
In "midi preference panel" I tried to create a "virtual" sound card but i am not able to get sound simoultanesly. or via hdmi, or via usb.
this is quite disappointing because if I want to listen to music with the amplifier and then watching a simple video with mac mini and tv only I need to go back to the audio preferences and set up manually each time.
Is it possible to solve this issue???
Thanks a lot and gretings from Italy

I can select ATV audio out (Airplay setting) to either my Airport Express or my computer so it must be transmitting via airplay. Using a combination of Airserver, Airfoil and Airfoil Speakers I managed to get the ATV audio content on both my PC and my Airport Express at the same time but it cuts out the ATV audio.
My aim is to have a movie on ATV transmitting the Audio to ATV AND my stereo (which is hooked up to the Airport Express).
Cheers

Can I use a USB DAC (Meridian Explorer) by connecting to the airport express usb port?

Sorry, but no. The AirPort Express provides either an analog signal or a Toslink optical digital signal at its audio jack.
The USB port will only support a compatible printer.

Is it possible to connect an external USB 2.0 hard drive to a Thunderbolt Display?

Hello,
Is it possible to connect an external USB 2.0 hard drive to a Thunderbolt Display and back up a MacBook Air to the external hard drive using Time Machine?
I intend to connect my MacBook Air to the Thunderbolt Display using a Thunderbolt cable.
I would also like to connect my printer via USB 2.0 to the Thunderbolt Display. Will this also work?
Effectively using the Thunderbolt Display as a USB hub or docking station.
Regards,
Ben

Ok, thanks.
My 1 cable to ThunderBolt Display objective
MacBook Air -> (via 1 x Thunderbolt cable) -> Thunderbolt Display -> (via 1 x USB cable) -> USB 2.0 external hard drive
I would like to know if this configuration is possible and Time Machine will run correctly.
Your 2 cable suggestion (I think)
MacBook Air -> (via 1 x Thunderbolt cable + 1 x USB cable) -> Thunderbolt Display + USB 2.0 external hard drive
This configuration requires 2 cables to disconnect/reconnect from my MacBook Air.

I can't print wirelessly using Airport Express. I have my HP printer connected to a USB hub, and the hub to the Airport Express, but when I select the HP from the printer list, my MacBook says the printer is "off-line" - even when it is not.

I can't print wirelessly using Airport Express. I have my HP printer connected to a USB hub, and the hub to the Airport Express, but when I select the HP from the printer list, my MacBook says the printer is "off-line" - even when it is not. I've tried several USB connectors, and several different ports on my USB hub; same result. I need to have the HP connected to the hub 'cause from there it's connected to our desktop Mac.

Hi,
I am currently replying to this as it shows in the iChat Community.
I have asked the Hosts to move it to Snow Leopard (you should not lose contact with it through any email links you get)
I also don't do Wirelss printing so I can't actaully help either.

Is it possible to print from Windows 8.1 to a printer connected to the USB port on an Airport Express?

Is it possible to print from Windows 8.1 to a printer connected to the USB port on an Airport Express?
a) HP printer with USB port only (no ethernet port) connected to Airport Express
b) No issue printing from Macs
Tests
1) Installed Bonjour 2 - does not find printer (now uninstalled)
2) Bonjour 3 is listed in programs but no way to access
3) Using TCPIP address (and no Bonjour) gives 'Unsupported Personality' error when printing test page
Regards
Richard
p.s. why are all Windows 8.1 questios n the forum 'Locked' with no reply?

This is possible, but not with Bonjour or any other fixes. It is just a printer set up based on the Port name of the Airport, 10.0.1.1.
I found the answer on YouTube, Title: Windows Printing For Apple AirPort Extreme without Bonjour Wireless wifi.

Can I use a USB hub to connect to multiple USB ports from one GPIB-USB-HS?

I have one instrument which has a GPIB-USB-HS connected and the USB cable is connected to a USB hub. Can I have multiple PCs to connect using USB hub at their respective USB ports? If so, how many PCs can I connect using the USB cable?
I have downloaded the latest NI-VISA from the website.
Solved!
Go to Solution.

You would first need a hub that allows you to switch between multiple pc's and then only one pc at a time would be connected and in control.
When you buy this special type of hub, one of the specs is how many pc connections it has.

Hi
does anyone know how to fix the message on my iMac:
"Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled."
This is a brand new machine and did not have anything attached to the USB ports"
Thanks for any help

If you are getting that message on a brand new Mac with nothing connected to the USB ports, take it back. It is broken.

Why can I no longer use my exterior speakers connected to the USB port on my MacBook pro

QuestionWhy can I no longer use my exterior speakers connected to the USB port on my MacBook pro ?

Have you checked the Sound Preferences under the System Preferences and set it to USB speaker for the sound output? Sometimes it can change on its own or after and update of an App or the OS?

HP Color LaserJet CP2025dn Printer Wired Connectivity and have USB simultaneously?

Hello to all;
Thank you in advance.
I have a HP Color LaserJet CP2025dn Printer.
The question, can I use ethernet connection and have USB simultaneously? Ethernet is faster, right?
Currently, I have the printer connected to network via Ethernet Wired Connectivity through an Apple Aiirport Extreme base station. I have several Mac's all operating under 10.9.1, and two PC's (one is WIN XP, and the other WIN 8.1), which all operate fine with 2008 wired/wireless technology. I know what a dinosour. I am in the process of upgrading the household to current wireless technology with a NetGear AC1900 Nighthawk Smart WiFi Router (Model: R7000), 802.11ac Dual Band Gigabit, with two USB ports ((1) 2.0 and (1) 3.0) . I connected the printer directly into the Netgrar router, and it wouldn't print, ran setup through the Mac and Win computers and still wouldnt pring. One of the reasons that sold me on the Netgear router was the ReadySHARE® USB access—Wirelessly access & share. In order for me to utilize the ReadySHARE® feature is to connect via a USB cable. Sob story, the longest USB cable off the shelf usually 16", and to reach where the printer is now, I need @25-28 feet of cable. Is ther a maximum length of USB that I can use with out suffering loss of speed/functionality?
Again thank you for your time

I am sorry, but to get your issue more exposure I would suggest posting it in the commercial forums since this is a commercial printer. You can do this at http://h30499.www3.hp.com/hpeb/
