How can I see my USB device in the measurement&automation explorer?

I'm trying to use an USB-device with LabView7.0.
I followed the manual "using NI-VISA3.0 to control your USB device" which I found on the NI-webpage.
I generated an .inf file using the VISA driver developement wizard and installed it in the INV folder of my system (I'm using Win2000).
The following problems occured: after I connect my USB device the "add new hardware wizard" pops up and aks for a driver for the new hardware. when I direct it to the folder with the generated .inf file it doesn't accept this file as a driver.
second: the USB device doesn't appear in the measurement&automation explorer. I assume that as long as my device doen't appear there it is not recognized by NI-VISA and the comm
unication from LV wouldn't work?
How can a make my USB device visible in the meas.&aut. explorer?
Regards
Tobias

Tobias,
In the VISA Driver Development Wizard, you are required to specify the Vendor and Product ID. These numbers are what Windows will use to determine whether a specific driver is appropriate for a given device. If these numbers do not match between your device and the Windows driver (INF file) that you generate, you will see the behavior that you describe. Check to make sure that you are using the appropriate values. Also, did you right click on the INF file and install it as directed in step 2.2.2?
Page 5-87 of the VISA Programmer's reference manual specifies how to do a viOpen to a USB device in RAW mode, but you still need the same sorts of Product ID and Mfg ID that you needed for the INF file generation. Furthermore, if you are communicating with
your instrument directly, you will need to know exactly what command set it expects, so make sure you get that from the manufacturer as well. Finally, I want to mention that if this device complies with the USBTMC standard, then none of this is necessary--the steps above are for setting up a RAW USB connection. See this link for information.

Welcome to Apple Support Communities
That's normal. You have to set up Finder to show external drives on Desktop.
To do this, open a Finder window, go to Finder menu (on the menu bar) > Preferences > General, and mark "External disks"

How do I see a USB device attached to AirPort Extreme?

Alright guys, I have been browsing around in search of an answer, but I've found nothing definitive about this. If I missed it, please be so kind as to put me towards a working link.
My question is the following. I have an AirPort Extreme 802.g, 5th generation, and a MacBook Pro 2012 with Lion installed on a SSD (downgrade from Mountain Lion). The setup of the airport was problematic enough with Utility 6.0, so eventually I (needlessly) uninstalled it and got the 5.6 version, which in fact works like a charm and is of great assistance too in troubleshooting any problems.
However, the problem is that I cannot manage to utilize the self-powered docking bay (functioning as an external HD) that I plugged into the Airport's USB.
If I open the Utility, I can click on "manual setup" and see under "discs" that my device is recognized and listed properly as a HD of given capacity; but that's about it. In no other place on the OS can I see it, let alone open it. Tried the "network" folder, spotlight, and all that.
Any heads-up?
TIA
Chris
PS I haven't tried the printer yet, will do soon.

OK found the problem: the disc is formatted in exFAT. The Airport cannot see it. It does see and mount a FAT32 disc. I found out that it cannot see a NTFS, either, if anybody's interested...

How can I boot to USB device if no USB boot option in BIOS

I just purchased a Toshiba NB305-N410BL but am concerned as to how I would image the 250GB HDD if I can not boot from an external cdrom drive. I tried to backup to shared network folder but none show up on list. Only boot options in BIOS are HDD, FDD, and LAN. Thanks for all help in advance.

Hi, buddy-erp.
I don't know if my instructions apply to you because I only have the NB305 model. However, if you say you have followed all instructions, that is, 1) insured that no other USB devices are connected to your computer at bootup time and 2) have pressed F12 to enter the boot menu; 3) and then designated the USB flash drive as the source of the bootable restoration software you may need Toshiba technical support. I wonder if there is a BIOS update for your computer too. This may need to be downloaded and installed prior to beginning the restoration process. Nevertheless, as stated, I have a NB305 model and the instructions are clear. FYI (for your information), a virus infected my system and made certain changes to this process. Toshiba technical support informed me that the information displayed was wrong and the process outlined was unnecessary but did require technical support to restore it to the OEM default options.
Good luck.
Sincerely,
Bi-Ill

How can I see ACR is busy (updating the screen)

Hi,
I use an older PC with Win XP, PS CS6 and ACR 7.3
When I've made several modifications the pc is getting slower and slower.
I've read when ACR is working, there appears an icon like this:
But that is only in the beginnning when ACR is starting....so far I know.
Suggestion for next version of ACR:
Is it possible to change the mouse indicator in something like :
Why this .....than there is an visual working-indicator .....if you make little changes you can positioning the mouse on that aera .... and waiting....when the icon changes back to normal.... the screen-update is finished.......so you can better toggle between "before" and "after"

First, thanks for the answer.
Jeff Schewe wrote:
I think you are misunderstanding what the icon warning is telling you...ACR shows that yellow triangle when first opening a raw image in ACR...............
Ok I understand, the ICON was not clear to me.
The fact remains that ACR is busy updating.
..............Thereafter, depending on your cpu speed, and changes should update very quickly so there is no need for a any additional warnings.
This second reason is not clear to me.
In my case it takes 5-8 seconds before the screen is updated.
But I can NOT see exactly when ACR is ready (especially with small changes), I have to guess when it's done ............
I can see something in the histogram, but not always, and it is also not synchronized (with ACR's updating) .......
And not everyone has the latest / fastest model PC ......
And another mouse icon programming is peanuts (only 1 system call, isn't it) .....
And there are more programms that have a hourglass.....
So I do not agree with this argument.
But.............Maybe there are more people with a similar problem....or have an other suggestion for it?
Other suggestion: Now ACR is updating the histogram first and after that the screen is updated.
How about to exchange those two ? ...so that the histogram is (always) the final action that ACR does when it is updating the midifications that are made.

hi i have recently purchased a new MacBook Air from Curry's and i am concerned this is is not the latest model i.e. june 2013> how can i tell please?

Then take it back and buy one from an Apple Store.
Open System Profiler and look at the Model ID. It should read MBA 6,2.
The identifiers are:

Can't see my usb hd in the airport utility

I just got an Airport express that is working great, but I can't hook a USB HD to it. I reformatted the drive and made sure that it is recognized when I plug it into my computer, but when I plug it into the USB port on the Airport and run the Airport Utility nothing shows up in the "Disks" menu. Anything I'm missing? I have cycled the power on the Airport without any success.

Is this a bus-powered drive or does it have its own power supply brick?
If bus-powered, a powered USB hub is needed.

How can I delete a "e-mail" without the next email automatically opening?

I know with my iPhone 5 I can swipe to the left and delete a email in my inbox without the next unread email opening automatically. But with my iPad doing the same task I just mentioned doesn't work. It seems to still open up the next unread email if I delete or even if I delete it the edit way. In fact it seems like if I do it the edit way once I check off the circle to select what I want to delete it still previews or opens the message. Is their a way around it? I like to be able to just look at my 3 lines of text of the email and decide if I want to delete it without it opening and I like to be able to open a message that I want to open, but I don't want to have it open up the next email automatically because I may not want that next email to open.

Yeah!! Edit to delete opens the email you want to delete before you can delete it!! I don't want to open those creepy spam phishing emails!! So now I just let them pile up and go onto my PC to delete them, where I have the option of not opening them first. I came on here looking for an answer but I'm just finding snarky retorts with no answers! :(

Can't see my USB Devices in Finder.

I am running the latest update of OS X Yosemite and within the past couple days, I can no longer see my plug in devices, ie. External Hard Drive, DSLR camera, etc.
When I pull the plug out of the usb port, I get a message that says I didn't eject the disk properly. What gives?
Any advice is appreciated.

Well the I figured out the solution....I shut down & restart the system. Sometimes its the little things.
