Windows 7 SP1 USB Driver Installation

Hi, I'm trying to connect my new MBL1330N controllers to my Windows 7 SP1 PC via USB.

When I power on, I get a green Pwr LED with a fast blinking Stat LED, followed by a green Pwr LED and a slow blinking Stat LED. When I plug in USB, the USB light goes on and my computer makes a sound indicating the connection. However Windows recognizes it as an "Unknown Device." and won't work with the DFU Driver included in the Roborun Plus installation.

Is there anything I'm missing here, or are there troubleshooting instructions for this? I'll be switching to RS232 for now but need to get USB working for simultaneous monitoring/debug connection. Thanks.

Open up control panels and then hardware and sound. From there locate the device manager. Inside device manager look for "comports" and the "unknown device". Open the unknown device properties menu, and click on the dirvers tab. Click on update drivers.

You will also need the xml file for the roborun+. Unzip the folder I have attached and place the xml in the following directory.

C:/program files(x86)/Roboteq/Roborun Plus/trees.

This is what I have been doing already -- when I click "Update Drivers" I get the option to either "search automatically for updated driver software" which determines that it is already up to date, or to browse manually for driver software. Searching the Roborun folders doesn't work, and specifying STDFU.inf with "Have Disk..." gives 4 options:

-- uPSD - DFU STMicroelectronics Extension Application Demo
-- Composite - DFU STMicroelectronics Extension Application Demo
-- ST7 USB Low Speed - DFU STMicroelectronics Extension Application Demo
-- STM Device in DFU Mode

I get warnings about unsigned drivers for each one, and it fails installing it with "Code 10" which is "This device cannont start."

Any suggestions on how to get USB up and running?

Try uninstalling the failed drivers first so that the computer no longer sees it. Then unplug the usb from the controller. Power on controller first, and then plug in the usb. When the computer sees the usb, look for 1 of 3 things.

1. Error "USB has malfunctioned...."

2. "USB not recognized...."

3. The usb drivers will start to install.

Though we have paid for the usb driver signing, you can try one more option. This is a known fix for the windows 8 plateform, but you can try on your windows 7 machine.

When I try this, I get the #2 message "USB Device Not Recognized."

What else can I try?

Is your USB plugged all the way into the controller? Sometimes the rubber bezel on the usb prevents the usb from inserting properly into the controller usb port.

Yes, the USB is plugged in all the way.

You can try a different usb port if you haven't already done so.

Also if you take out the screws on the bottom of the unit, you can easily remove the cover. Take a look at the usb pins. There should be a solder bridge on 2 pins (pins furthest away from the I/O connector).

Otherwise, have you tried connecting it on a different computer?

I finally got to try with another computer now, still get the same problems. I've been able to just use RS-232 for my application so this hasn't been a big issue for me, but would be nice to get working.

Unfortunately the way these are installed it's tough to get them out to remove the cover and look underneath. I will do this next time I take the apparatus apart.
