Drive higer load with the usb 6008
Hi all,
I need to drive a small motor with the analog output of the usb6008 device ... connecting it directly doesn't seem to work.
Any suggestions how get it working??? what does the 6008 output?
My motor works on a AAA battery dricetly.
Thanks a lot

The analog outputs of the USB-6008 are only rated at 5 Milliamps per
channel. One suggestion for getting it to work is to use an emitter
follower to get more current to drive your motor.

Should I get a 2.0 or 3.0 USB external hard drive for my 2011 Macbook Pro? I need it to be compatible with the USB ports of both a PC and a Mac. I was thinking of getting a Seagate becuase apparently it is compatible with both systems, but I want to know which would be a better investment.

My Apple desktop computer, 2.4 GHz Intel duo core, OS 10.6.8, stopped recognizing the WD My Book connected via firewire. It works fine with the USB port so it's not the drive. Help please?
It can be the bridge. It could need firmware update. or the FW ports may be an issue. LaCie seemed to invent the phrase/tip 'resetting firewire ports' due to the issues with their drive cases.
You can try an SMC Reset.
So far I have avoided name-brand and tend to see them mentioned. Often with a new OS (though you are on 10.6.8, but when 10.6 came out there was a common complaint and thread of users: FW or USB worked but not the other interface). -
Tried to upgrading ipad 1 from itunes and l guess it did not complete the process because all I have showing on the ipad is the itunes logo with the usb cable. When l try to connect it to my system, it resquest that a driver be used to install the device. Please help! How do I restore?
Restoration is relatively simplistic. Here's whatcha do. Plug your ipad in, open itunes, now if itunes doesn't recognize it then you may have a problem, anywho, click on the ipad in the devices interface and go to the info tab, click restore, and it'll be just like it was when it left the factory. To get you data back, it should ask if you would like to use a backup, just select the backup you want and you'll be good to go. That is if you regularly backed up your iPad.

Laser operation with a USB 6008 DAQ
I'm wondering how I go about using the USB 6008 DAQ in conjuction with labView to turn on and off ths laser:
http://www.maplin.co.uk/p/1mw-3v-red-laser-module-le07h
The laser must be turned on using 3V which isn't possible with this DAQ. I was thinking of usinga BC 109 transistor, then have the laser connected to an external power supply which is supplying 3V to the laser. then have the laser connected to the collector of the transistor.
I set this up and it didn't exactly work out as the laser was drawing to high a current and not working correctly.
Can anyone help me?OK. The problem is that you need to supply about 30 mA to the laser to get it to work. The digital outputs of the USB-9008 are limited to 8.5 mA or less. Furthermore, a laser diode is a current operated device. If you apply a fixed voltage the current will vary depending on the exact doping used when the device was manufactured and on it instantaneous temperature. The curretn rises exponentially with voltage as in any diode. The link you posted does not have any real data about the electrical characteristics of that diode.
Typically a current regulating circuit is used to drive laser diodes. The simplest circuit is a resistor in series with the diode connected to a power supply with a voltage higher than 3 V. The value of the resistor depends on the power supply voltage, the voltage drop across thes witching transistor, and how much current you want to run through the diode. If you have applied 12 V to that laser from a source which can provide substantial current (>50 mA), you have probably destroyed it.

I used to be able to just plug in my phone with the USB cable to my Windows 7 computer and browse phone storage with no issues. Now my computer sees it as an android phone but when it tries to automatically install the drivers for my phone on the computer, i get an access denied error message. No option on the phone that i can see that allows me to mount phone as a usb drive. This used to work just fine with nothing more than just hooking up the cable. What gives??
Let's get that access granted again, e_rock_b. The HTC DNA doesn't have a special USB Mass Storage Mode that needs to be turned on. Usually, it's as simple as connecting and browsing http://vz.to/1jktbZD as you mentioned. If your computer is no longer allowing that easy access, try the steps at http://vz.to/1jktvr6.

I just received a new macbook pro. I am looking for a usb3 external storage 500 GB drive. Some manufacturers of drives aren't for sure their drive will work with the new system. Does anybody have any suggestions for drives that will workw
There seems to be a problem, just now, with the USB 3 ports on the new MBP's supporting eternal USB 3 drives. Some people have no luck at all - can't even recognize the drive - and some are reporting USB 2 speeds (those who drives are recognized). I'd call a dealer such as LaCie or OWC to see if they have USB 3 drives that actually work with MBP's with USB 3 ports. You may have to wait for a software/firmware update.

Reading an encoder with a USB 6008
Hello DAQmx users,
I have a USB 6008 and it doesn't work the way I want it to. I have done no troubleshooting or research and I refuse to give you any more information. You have 30 seconds to answer my question. i kid, i kid...
So here is my real question:
I have a USB 6008 that we use to do simple analog output. I'm looking for a way to use the USB 6008 to also get encoder information. I know that the USB 6008 cannot read an encoder directly, but I was wondering if anyone knew of or had any ideas of external hardware that could be used inbetween the 6008 and the encoder. I think it would be something like 1) the encoder generates pulses 2) external hardware takes encoder pulses, translates them into a digital value representing the angle and outputs this digital value 3) use the digital lines on the 6008 to read in the digital angle value from the external hardware 4) I don't lose my job.
I realize that this isn't an easy, optimal, or preferred solution, but I want to look into it before being forced to replace the USB 6008 with another piece of hardware.

Hi there,
I writing this because I'm having some really big problems with my USB ports.
A few days ago I plugged in an USB-Hub that was quite cheap. Suddenly a window popped up saying that a USB device was deactivated because it "needed" to much power. Since this happening, two of those windows keep popping up everytime I boot the MacBook. I called Apple and got some help: I had to delete some .plist files and clear some caches. The man who helped was able to find the error and deactivate the notification, he also told me to make a PRAM- and a SMC-reset. The man said that it's just a software problem and that I have to reinstall the system if we don't find a solution. So, one day later I reinstalled the system (Lion) and not only didn't it help, the two notification windows were popping up again...everytime I booted the Mac. So I decided to formate the whole hard drive and install Snow Leopard -> still the problem with the USB ports. After that I installed Lion -> still the problem with the USB ports. I even tried to extract the .kext files that are important for the USB functionality from an earlier Combo Update, but it didn't help either. The point is, that the Mac doesn't recognize my external hard drive or any of my iDevices. Sometimes it recognizes USB sticks, but only after 20 seconds. The data transfer on both USB ports is also very slow. If I'm lucky and Mac recognizes one of my USB sticks, it takes like an hour for 1GB to be transfered on the USB stick or from the USB sticks to the Mac.
I really don't know what to do and need help, especially because my backup data is on my external hard drive which I can't access because of this problem.
I really hope that someone can help me, I'm very thankful for every answer that could help me!
PS: Sorry for my bad English, I hope that everyone understands what I mean, please tell me if you don't get what I'm trying to explain in the text above.
Sincerely,
iLoud
[UPDATE] I downloaded "USB Prober" and copied the Output file, maybe it helps:

FCP X is loading and loading with the colour wheel revolving for ever for the past few days.
FCP X is loading and loading with the colour wheel revolving for ever, for the past few days.
FCP X was working fine in my new 15" Mac book pro (Retina display with Mountain Lion 10.8.2) for the past one month. Now a days, each time I try to open the FCP X, the same non-stop colour wheel is rotating, trying to restore one of my project. It continues even for hours together. Finally I am force quiting the application.
How do I come out of it ? Will I be able to recover my project. I didn't do any backup in particular.
Is backing up on the regular basis is required?
I tried the following guidance by Apple,
In the Finder, hold down the Option key and choose Library from the Go menu.
In the Library folder that opens, go to Application Support/Final Cut Pro.
Drag the Layouts folder from the Final Cut Pro folder to the Trash.
Still my problem is continued
Help meThis is my pet checklist for questions regarding FCP X performance - you may have already addressed some of the items but it's worth checking.
Make sure you're using the latest version of the application - FCP X 10.0.5 runs very well on my 2009 MacPro 2 x 2.26 GHz Quad-Core Intel Xeon with 16 GB RAM and ATI Radeon HD 5870 1024 MB. I run it with Lion 10.7.5.
First, check that you have at least 20% free space on your system drive.
For smooth playback without dropping frames, make sure 'Better Performance' is selected in the FCP X Preferences - Playback Tab.
If you have not already done so, move your Projects and Events to a fast (Firewire 800 or faster) external HD. Make sure the drive's formatted OS Extended (journalling's not required for video). You should always keep at least 20% free space on the Hard Drives that your Media, Projects and Events are on.
Check the spec of your Mac against the system requirements:
http://www.apple.com/finalcutpro/specs/
Check the spec of your graphics card. If it's listed here, it's not suitable:
http://support.apple.com/kb/HT4664
If you are getting crashes, there is some conflict on the OS. Create a new (admin) user account on your system and use FCP X from there - if it runs a lot better, there's a conflict and a clean install of the OS would be recommended.
Keep projects to 20 mins or less. If you have a long project, work on 20 min sections then paste these into a final project for export.
If your playback in FCP X is not good, I strongly recommend you use ProRes 422 Proxy - it edits and plays back like silk because the files are small but lightly compressed (not much packing and unpacking to do) - but remember to select 'Original or Optimised Media' (FCP X Preferences > Playback) just before you export your movie, otherwise it will be exported at low resolution.
The downside of 'Proxy' is that it looks awful. DON'T use Proxy when you're assessing things like video quality - especially focus.
If you have plenty of processor power, for the ultimate editing experience, create Optimised Media - most camera native files are highly compressed and need a great deal of processor power to play back - particularly if you add titles, filters or effects. ProRes 422 takes up much more hard drive space but is very lightly compressed. It edits and plays back superbly.
Personally, I work with XDCAM EX and h.264 from a Canon DSLR. Both of these run fine with my system, but I do transcode multicam clips.
Hide Audio Waveforms at all times when you don't need them (both in Browser and Storyline / Timeline). They take up a lot of processor power. (Use the switch icon at the bottom-right of your timeline to select a format without waveforms if you don't need them at the moment, then switch back when you do).
Create folders in the Project and Events libraries and put any projects you are not working on currently, in those folders. This will help a lot. There's a great application for this, called Event Manager X - for the tiny cost it's an invaluable application.
http://assistedediting.intelligentassistance.com/EventManagerX/
Unless you cannot edit and playback without it, turn off Background Rendering in Preferences (under Playback) - this will help general performance and you can always render when you need to by selecting the clip (or clips) and pressing Ctrl+R.
The biggest single improvement I saw in performance was when I upgraded the RAM from 8 GB to 16.
If none of this helps, you might have incompatible or corrupt media or project files. Move ALL your Events and Projects to temporary folders so that FCP X doesn't find them on launch. If it launches OK, re-introduce the Events and Projects one at a time, re-launching each time, so that you can track down the corrupt or incompatible files.

Input Capacitance of the USB 6008
Does anybody know the input capacitance of the NI USB 6008? Im creating a circuit that mimics a 10x probe whose design requires the value of the "oscilloscope" input capacitance, or in this case, the USB 6008 input capacitance.
Thanks so much!With the low input resistance (144 kohms) the capacitance does not matter much. Any realistic value of input capacitance will have a time constant shorter than is meaningful for the device bandwidth.
Also note that the input impedance is terminated in about 1.4 V. See the circuit in Figure 7 of the User Manual.

Measure like the testpanel of the USB-6008
Hello,
I want to measure like the testpanel of the USB-6008. What is the right
example of the nidaq installation or what are the necessary c-functions?
The most c-examples quits with an error. So I don`t no what is the right. I searched in the dictionary "Analog In".
Thx PellaeonHello,
you can find all examples for DAQ in C:\Programme\National Instruments\NI-DAQ\Examples\DAQmx ANSI C\Analog In\Measure Voltage.
Do not forget adding the include file and the library file to your project. That is described under NI-DAQmx C Reference Help. You can find this under Start->Programs->National Instruments->NI-DAQ-> NI-DAQmx C Reference Help and there under Getting Started--> ANSI C
USB-6008 is supported in NI-DAQmx 7.5 or NI-DAQmx Base. http://digital.ni.com/public.nsf/websearch/4D915A820A76823C862570390075EBF5?OpenDocument

NVIDIA OpenGL driver lost connection with the display driver
Alienware M14x Laptop
Windows 7-pre 64-bit
8gb ram
3gb Video: NVIDIA GeForce GT 555M
Intel i7 2760QM
AE CS4
AE keeps crashing. I get the following message while doing something as simple as scrubbing through the timeline, or changing opacity of a layer. in 1080p, I have a picture layer, a solid, some color corrections, and that's it. i just got this new computer and i have never had this problem on my old computer.
this message appears after AE crashes."The NVIDIA OpenGL driver lost connection with the display driver and is unable to continue. The application must close."
this message appears in the taskbar: "Display driver stopped responding and has recovered. Display driver NVIDIA Windows kernel Mode Driver, Version 267.21 stopped responding and has successfully recovered"
any ideas on how to stop AE from causing my display driver to stop working?
Thanks, Ramzi RebeizFor anyone picking up this thread (it's probably too late for rrebeiz40 by now!) I have come across a simple but apparently very effective tip that has solved the 'OpenGL driver lost connection' issue for many people using various NVIDIA with various Adobe progs (incidentally a lot of these seem to crop up on Dell machines, especially Notebooks).
(It fixed my issue with Premiere Pro CS4 - GeForce GT 555M on Win 7 Ultimate 64-bit, Dell XPSL702X).
It's posted on http://forum-archive.developer.nvidia.com/index.php?showtopic=5331&st=40 (look for the last post, No 50) as follows:
THIS FIX APPEARS TO WORK...found on an Adobe forum
"This issue led me to this fix: go to NVIDIA Control Panel --> Manage 3D Settings --> Global Settings, and switch "Power Management Mode" to "Prefer Maximum Performance" (the default "Adaptive" setting seemed to be the culprit). And that's it! The key here is changing the "Global" setting, as my individual programs were already set to "Prefer Maximum Performance." I can cause the error to reoccur by changing back to "Adaptive."
Otherwise lots more ideas on this site: http://www.instructables.com/id/How-to-Fix...Nvlddmkm-Error/
