Unable to Open Serial Port for UBW32

[perkinsck]

I got a [ USB 32-Bit Whacker (DEV-09713) last year so I could try to prototype various projects, but I’ve had trouble doing anything with it.

I took some time today to try to follow the [ quick start on Brian Schmalz’s page, but instead of using the driver linked there, I downloaded the one from the product page.

I plugged my UBW32 into my laptop (running Windows 10) and the blue PWR led turned on.

Nothing came up for new devices, so I tried manually installing the UBW32 driver using PnPUtil. It seemed to work fine. Then I went to Device Manager and selected Action->Add Legacy Hardware. I went through the wizard:

download/file.php?mode=view&id=7200 download/file.php?mode=view&id=7199&sid … 2a422bc110

Now my board seems to appear under the “Ports (COM & LPT)” list as “USB Serial (UBW-based) communications port (COM4).”

Despite the Code 10 message pictured above at the end of the wizard and also in the device’s properties, I tried setting up a serial connection in PuTTY. I turned off flow control, used 9600 baud, 8 bits, 1 stop bit. When I try to connect I get this message and PuTTY quits:

download/file.php?mode=view&id=7201&sid … 2a422bc110

I’ve tried different USB ports and USB cables.

I’ve tried installing the driver from Brian Schmalz’s site and it wouldn’t install.

I have a PICKIT 4 but I don’t really know how to use it.

Any tips on how to get this working would be great.](UBW (USB Bit Whacker) Project)](https://www.sparkfun.com/products/9713)

You might have some luck trying these 2 things:

Disable Driver Signature enforcement in the PC…sometimes legacy stuff doesn’t work well with current Windows versions

Try the steps here http://www.schmalzhaus.com/UBW32/doc/UB … ation.html and see if you can get it to enumerate as a generic HID device

Lastly I’ve never used a Oickit4 either, but it looks like there are some instructions on how to use the PickIt here http://www.schmalzhaus.com/UBW32/doc/Fi … tions.html

Thanks for the response.

I tried to Disable Driver Signature enforcement and reinstalled the driver. No luck there.

I’m glad you pointed me to this documentation though - I noticed that the USB LED was not lighting up as described for the bootloader/generic HID mode.

Something I had left out of the OP is that I didn’t have a Mini-B USB cable to match with the USB jack on the board - I had soldered pins onto the breakout terminals for the USB and wire wrapped these to a SparkFun micro-USB breakout (I placed the pins on top for an aesthetic reason).

I ended up finding the right USB cable in a box at work and I plugged it in. It works fine now.

I repeatedly checked that the wire wrapped pins were connected. I double checked by testing continuity between the pins on the Mini-B USB jack and the micro breakout. Is there a difference between the two jacks that I’m missing?
