MSPDebug rf2500: failed to open RF2500 device error Launchpad

Recommended Posts

When I run mspdebug from the command line I get this failure:
Microsoft Windows [Version 6.0.6002]

You need to specify a driver. Try --help for a list.

rf2500: failed to open RF2500 device.
But mspdebug can see the Launchpad:
C:\Users\Mark>mspdebug --usb-list

Running testlibusb-win.exe gives me this:

So it looks like libusb-win32 is installed right. It also looks right in Device Manager.
This is on Vista64. The Launch pad has the 2553 installed but I backed up to the original chip that I had used under gdb in a previous msp430 tool chain I know worked, same error.
The mspdebug I am using is from the pre compiled MSP chain XPG provides, just to limit the variables. I have tried forcing the serial number but that made no difference. Do I need another version of mspdebug than the current (0.20?) that's in the provided chain?
Any ideas on what to do next?
If there are any logs that would be useful in figuring this out just ask.
After going back over the install several times and reading posts till my eyes are blurry I am still stumped.

Anyone with the solution to this issue, perhaps?

Windows7/64, supposedly all drivers installed (COM3 for the MSP USB UART here), mspdebug sees the device, but just can't open it. Everything like MWE said.

(The suggestion from ikravets results in "This driver does not support raw USB access.")




In the libusb driver package (mine is the SysProgs version), do run inf-wizard.exe to generate the correct .inf for the actual MSP430 debug interface. Then you just install it (can be done right from inf-wizard), and the device finally appears (under "libusb- win32 devices" under Device Manager), and mspdebug can access it, at last!
Hallelujah! :)
