MSP430F5659: Problem implementing USB software into an existing project.

So...

Found the problem, but its something I wasn't expecting.

Apparently, the USB Descriptor Tool program is creating an invalid descriptor.

If I copy the descriptor information files from the example program, it works fine.  If I use the descriptor tool to create the configuration I actually want, it is either ignored (won't enumerate with the host), or it will actually 'hang' the host during enumeration.

Unplugging the board from the USB is the only way to get things back on track.

This fails both on my target program, as well as the example.

Is there a corrected version of the Descriptor program, or has TI just totally dropped the MSP430 support?  Seems there's not much in the way of support any more.

ALSO... this new 20.1.0.6__1.7.0 CCS is a piece of crap.  Whoever decided this was the way to go definitely decided wrong.  It locks up, fails to recognize the MSP430-FET unit half the time (only way to get it back on is to unplug and replug it), may/may not decide to program the target device, decided launch.json doesn't exist, or isn't valid (requires exiting CCS and reloading),... and a number of more things.  I HOPE there is a new version coming that will fix this garbage.  Otherwise, have to seriously think about continuing to use these products.

Don't get me wrong... I LOVE the MSP430 product, just quality of the programming environment has gone down over time.

Hi David,

So sorry for late reply.

The newest version of USB Descriptor Tool is v5.0.11.22 : MSP430USBDEVPACK Application software & framework | TI.com, are you using this version?

And for the MSP430 USB API & Descriptor Tool guide, you could refer to: Programmer's Guide

I would also recommend looking at below posts for the similar topic:

That's the version I have installed.

This is on Linux.  On our internal research network, no Windows boxes is allowed.  We have Windows on our outside office network, but it's for email/web and so on...

No development here goes on a Windows machine.  Which is another problem, they want to do a Hercules project, but that's not supported on Linux.

Enough complaining.....

I can copy the files from the example project and the USB works fine, but if I try and create a custom configuration,  it doesn't work.

Eventually, I'll get to the heart of the issue, but don't have time right now, so I'll just patch in the example configuration.

Hi David,

Understood.

Actually making modification based on a SDK imported project is also the most common way that we build our project. Hope things works well with you .
