Thank you for testing this out. The severe problems that I e-mailed
originally were certainly the result of several USB hubs that did not
work correctly with the motes. I have managed to find more
appropriate connections that do not result in this issue, at least
not so severely. However, the issue has come back up sporadically,
even when the application and connection were tested for over an
hour.
As you will see from my previous messages to this list, however,
there appears to be a high sensitivity to the appropriate type of USB
connections. Others have also experienced this issue. I am wondering
why this is the case and/or how this may be improved.
Thanks,
Tal
