    Driver Issue in Windows 7

    Hi,

    I have recently encountered an issue in Windows 7 where every time I plug in the VCDS USB lead, Windows does not automatically load the driver. VCDS 12.2.2 plus driver package is installed.

    I am greeted by this in device status in device manager.



    I try to update the driver and he response is no driver found. I then point the manual installation to ross-tech/VCDS folder and still drivers not found. To get around it, I have to disable the device in device manager and re-enable and then the driver is found and the device functions perfectly. Kind of tedious. I have tried removing USB ports, reinstalling them, removing hidden usb devices, reinstalling. Still the same. Any idea what this could be? It's not enough to warrant a reinstall of Windows but if someone has worked out whats going wrong here, please can they let me know. Thanks.

    Click on the Details tab please, and show us the Device IDs. It should look something like this:



    (I'm at home in front of a relatively ancient machine running XP -- one of these days I get around to putting W7 on it. Maybe.).

    I wouldn't bother, Windows 7 does have it's own issues, if it ain't broke





    It has been working fine for years by simply plugging in and off we go...it's the little things that take the time to fix...I am sure this is a Windows issue.

    I'm not sure. Looks like the VID and PID are hosed. But try some other computer. You don't need to install any software or drivers, just plug in the interface and see what VID and PID show up on the other computer using the same technique. The VID should be 0403 and the PID should be FA2x. I don't have that (early) generation Micro-CAN hand and don't remember exactly what x is for it (somewhere between 0 and 4).

    It's a problem with my Windows installation. What it is I don't know. Not a big deal, if anyone has solved it though without a re-installation please do post a follow-up. Thanks.

    It works on my Windows 7 32bit SP1 just try a reinstall. Remember to click the separate USB driver install and click always trust Ross-Tech.

    Unlike the first set of stuff you posted, this looks OK. Is that from a different computer?

    It has been working on my Windows 7 installation for a couple of years without any messing, then suddenly it decides not to play. Trial and error found that disabling then re-enabling in device manager solves the issue. Weird that the driver is not found or can't be manually installed on initial USB connection though (exclamation next to device). I can't justify a Windows 7 reinstall at the moment as I have a workaround, but if there is a cheap and cheerful fix, all the better.

    Yes from another computer. This is also what shows when I disable the device in device manager then re-enable it, on the problem computer. Comes online without any further effort every time.

    That's definitely strange, and not something I've seen before.

    Strange indeed. Is the only place to point to the Windows 7 driver /rosstech/VCDS and ../system32/drivers (RT-USB.inf) ?
