Hi,
I used the DebugView, but when I use the bulk program, it only returns two
blank lines. When I use the test program, it returns lots of things. Here
are the logs:
*bulk.c:*
(two blank lines).
*test program:*

I made some tests and got even more confused: if I jump the first and second
devices, testing the third (or fourth) device first, I still get the same
error. So would it be a power or bandwidth problem? I'll think of some more
tests to do and will post here if I find something that could help.
Thanks and cheers!
