'usb-storage' and 'ub' modules with usb floppy drive and usb flash key
I built my kernel (2.6.16.5) with 'usb-storage' and 'ub' drivers asmodules.when I plug in a usb flash key, the modules 'ub' and 'usb-storage' areloaded, I can check it with lsmod.The drivers node the key to uba1, so I can mount it. when i unplug thekey (after unmouted it) the node uba1 disappears and everything isfine. I can plug or unplug the key whenever I want it works fine.I got a usb floppy drive not long time back, when plugged in, the'usb-storage' module is loaded and the driver nodes the drive to sdb(sda is my sata hard drive) I can mount it and unmount it, it worksfine.everything fine until I then plug in the usb flash key. the 'ub' moduleis loaded, but the node uba1 is not created. I tried to see whether thedriver didn't node it with sdc, and right it did. but when i mount itan error message appears:mount: you must specify the filesystem typewhich I never have to usuallyso i tried to mount the key specifying the fs type with -t vfat, but iget this following error:mount: wrong fs type, bad option, bad superblock on /dev/sdc, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or sodmesg:VFS: Can't find a valid FAT filesystem on dev sdc.usb-storage: queuecommand calledusb-storage: *** thread awakened.usb-storage: Command TEST_UNIT_READY (6 bytes)usb-storage: 00 00 00 00 00 00usb-storage: Bulk Command S 0x4...
GPIB instruments connected through Agilent USB/GPIB Interface can bee seen in MAX but can't communicate in labview
I have an Agilent 82357B USB/GPIB Interface connected to my computer. Attached to that, I have two lock-in amplifiers (an SR830, and an SR850).  I would like to be able to communicate with them through GPIB. I have downloaded and installed the software for the Agilent device(Agilent IO Control), and I can see the interface and the two devicesin that software.  Here's what is configured in this software, that Ican see:- The VISA interface ID is GPIB0, and its address is 0 - The VISA addresses of the devices are GPIB0::4::INSTR and GPIB::12::INSTR, and the GPIB addresses are 4 and 12In Measerment and Automation Explorer (MAX), I made sure that thePassport for Tulip box was checked.  Once it was, I could see thedevices in the Configuration window under Devices and Interfaces ->Miscellaneous VISA Resources.  There, I see GPIB0::INTFC, GPIB0::4::INSTR and GPIB::12::INSTR.I can right click on either of the instruments, and 'Open VISA TestPanel' where I am successfully able to send commands and read from bothdevices.HOWEVER, when I am running an actual LabView program, I am unable to communicate with the devices.  For example, when I try to communicate to the devices through VISA,using the 'Basic Serial Write and Read.vi' (while VISA Resource Name isGPIB0::12::INSTR), I get an error: Error -1073807331 occurred at Property Node (arg 2) in VISA Configure Serial Port (Instr)...
Is it possible to run AM Modulation in LabVIEW PDA Module?
Hi All,        I would like to ask about AM Modulation vis can run on PDA Module or not?Because as i mention that PDA screen is too small to see all the AM modulation waveforms.So i would like to know whether is it pissible to run AM Modulation on the LabVIEW PDA Module? If it is possible, please tell me that how should i modified my VIs on block diagram and how do i arrange all waveforms graph on front panel?        Then, the AM modulation that i want to run is as shown in attach file.           Thanks to all for your help.  With RegardsNyan LinAM block Diagrams.jpg:http://forums.ni.com/attachments/ni/170/329390/1/AM block Diagrams.jpgAM Modulation front panel.jpg:http://forums.ni.com/attachments/ni/170/329390/2/AM Modulation front panel.jpg Nyan, I was able to replicate a VI similiar to your and deploy it on a Pocket PC 2003 PDA device (a Compaq iPAQ PDA); therefore, all your functions are able to be transferred over to a PDA. As far as arranging the waveform graphs I would recommend using a tab control, so that you are able to have each graph on a different tab (see attached screenshot). Hopefully this points you in the right direction and let me know if you have any further qu...

can LabView talk to USB devices by PC USB?
We have USB hardware that connects to the PC via the USB port which Iwould control by LV.Does a pll is exiting for this type of application? I am far from being quaified to answer this, but I can tell you thismuch.Due to the low level nature of USB, LabVIEW has no way of talking to ageneric USB device. If the devices is one of the standard classes(Human Interface Device for example), then there are Win32 functionsyou can call - although I have no clue where these are located. Ifnot, you almost always need drivers for the device which providecustom DLLs. If you do not have this th...

USB with LABVIEW / VISA
Hi all,&nbsp;I am a beginner in Labview. I had to develop a small prototype to read data from RS232. With VISA's functions and labview examples, everything worked fine.&nbsp;Now I would like to interface some USB devices by using similar VISA's components. In order to acquire skills in USB programming, I would like to build a simple program which for instance would get information on a simple USB device (as a USB KEY, or a USB mouse...).&nbsp;I already succesfully created specific visa drivers with the drivers wizard, installed them, see them with MAX.&nbsp;I studied the LV examples USBRawControl.VI and&nbsp;USBRawBulkMain.VI. But I do not succeed in getting any results. I guess I enter the wrong parameters in the example. Can anyone explain me a bit more how it works ? Or give me a set of parameters to test the LV example and get any results ?&nbsp;Thanks a lot.&nbsp;J�r�my&nbsp;&nbsp; There is, imho, no such thing as a simple USB device. For example, the USB mouse will automatically install itself using the windows HID driver so that it can be used as a mouse and creating a VISA driver for it will be be fairly futile unless you get rid of the windows driver and that would not be a good thing. I don't know what you mean by a USB Key.When a USB device is used that does not use one of the existing classes, you could create a VISA driver and use that instead of the driver that the vendor provides. You would however...

You should make sure that you chose the correct port in your LV program (I believe you'll need to restart LV after connecting the USB device before you'll see the port in the VISA resource list) and that all the serial settings are configured correctly both in your program and in the OS (Control Panel&gt;&gt;System&gt;&gt;Hardware&gt;&gt;Device Manager in Windows).Normally you can configure the port using VISA property nodes, so there shouldn't be any need to configure the device in the OS as well.
