    $10 paypal if you can answer this

    Paypal will be paid once your theory to the problem is concluded to be true.
    You guys will have to trust me that I will pay you.

    Problem:
    My company developed an USB device with it's correspond INF driver.
    We have tested the device on numerous computers, laptops, and desktop and everything works acording to specification.

    Last week we demo to a perspective buyer of the device. When the buyer tests the device (on two separate computers), the device fails installation on both systems. Buyer is a large company with standard and up-to-date equipment. Systems are both Windows XP Pro with SP1. Both systems were logged in as Administrator or a user in the Administrator group.



    typical installation process as follows:
    1) install software.
    2) plug in USB device
    3) Windows finds the driver and everything *should work*.

    What happens at the buyer's location is
    1) install software
    2) plug in USB device
    3) !! Windows can not find the correct driver for the device.
    4) When we force a driver match (hard code), Windows responds by saying that the driver chosen does not contain infomation for the hardware device (along those lines).


    The device and drivers have worked many many times before. The driver and device have been show to be reliable and worthy of sale.

    Questions: Is it possible that there is something on the buyer's computer that is preventing Windows from installing of the INF &/or hardware?

    Question: what on the buyer's computer can cause conflicts with the USB device?



    Cliff Notes: Can't install a USB device even through the proper driver is specified.

    Does the driver have any dependencies that may not be present on the client's machines (dll for example)? Are their machines the same OS as the machines you tested on?

    Any dependencies (if any) would be installed when the software is installed.
    We've tested out product on Windows XP, 2000, 98, and a few Linux distros.

    We're thinking it may have to do with the way the buyer's network/workstations setup. That's the unique variable that the buyer has that no other tested systems have.

    You said the client computers have xp with sp1. Did you mean sp2? perhaps you were only testing on xp with sp2.

    is your device built 100% to spec? Differences between USB chipsets could be the difference. Some are more leniant than others.

    Did you plug the device in before or after loading the drivers?

    check device manager in safe mode for any 'unknown devices' or some such, and delete them + references to your driver, then reboot and see

    This may sound really dumb and obvious.... but have you tried other brands of USB drives on your client's PC? Perhaps NONE of them work on it for some reason, in that case you can narrrow it down to a problem with his machines...

    How about taking a laptop and showing them that it is their setup and not the hardware or software.

    on thing I have noticed on some computers ihave worked on is you might try a registery cleaner sometimes that will work I have noticed that if I can't get a program to install or load on some computers I will run a reg clean and it works could be that simple. Worth a try

    I've had this problem with other hardware before, and unfortunately if the driver/hardware are loaded in the proper order (as yours was, now that I re-read the post) it usually comes down to a poorly written driver. I just replaced 4 Linksucks G PCI cards because of this same type of issue. The driver for these cards is a terrible retread of the broadcom spec drivers.

    We load the software first, and then we plug in our device.

    This was one of our thoughts as well.
    Any way to find out?

    Yep. and that's why it's very important we find the cause of this problem.

    We'll give it a try.

    We did send one of our engineers down to the buyer.
    He manually cleaned out the registry and reinstalled our software many times.
    Maybe we'll try a 3rd part registry cleaner.

    question #1, do other USB devices work on the system?
    question #2, are you going straight into the USB plug, or thru a hub?
    question #3, does your device require a memory address/IRQ that may be in conflict with another device currently on the computer?
    question #4, have you ensured that every/all DLLs used (even the 'common' ones supposed to come with windows) are included with your install app?
    question #5, have you tested the 'bad' device on one of your 'good' testbeds? it's possible there's a failure somewhere in that particular device
    question #6, are the same people who have installed the device on your testbeds installing it on your customer's computer? it is possible your salesperson is making a stupid error (ie not turning the device ON, etc), and there's really nothing wrong with anything
    question #7, can you send me a copy of the device/drivers so i can test it out here?
