Hi Tyler,
Are you using Windows 7 by any chance?
We have seen some issues with Woindwos 7 machines and the USB cables we ship (I know it sounds ridiculous, but its true). It is under investigation and will shortly be the subject of a blog.
Assuming you are a Windows 7 user, can I ask you to try an alternate cable (shorter, fatter and with a RF choke if you have one like that). You'll probably find this solves the problem.
Lee me know how you get on.
Thanks,
Chris
When I go to copy a binary file or delete a file off the mbed device it hangs. It get stuck in this Copying... dialog that just says "Calculating..." and never moves on. Any ideas?
