rf2500 issue for Mac OS X EI Capitan (have to unplug and plug again for work) #747

Open ghost opened 9 years ago

ghost commented 9 years ago

Hi there, I just updated my Mac to OS X EI Capitan. I encountered the rf2500 issue. Everytime after I write program to the launchpad, the system cannot recognize it again unless I unplug and plug it again. Any solution? Thanks.

This is what I got from the terminal:

Seems to be related to Mac OS X 10.11 and / or mspdebug. USB management is especially volatile on Mac OS X.

Have you contacted the developer of mspdebug at http://dlbeer.co.nz/mspdebug and https://github.com/dlbeer/mspdebug/issues?

Just sent email to him. Thanks for your reply.

I am having the same problem with El Capitan and my 5529 msp430.

I just installed the latest version of mspdebug 0.24 on top of Energia but still I have to plug and unplug my Launchpad 5529.

It seems to be a CDC/VCP driver issue rather an mspdebug?

Almost certainly an OSx issue; I hit this issue some time ago and have been putting-up with it for ages. I also found it was intermittent and would occasionally work for 2 or 3 times without unplugging.

The USB drivers are unstable with Mac OS X 10.11. Each release changes the way they are handled.
