yep with batteries removed
Tuicemen -- I'm sorry to report that the USB connection has again failed after the following interpretation of your recommended procedure:
1) Disconnect USB from computer (if connected) and unplug the interface from A/C; remove the batteries; let it sit for one hour.
2) Meanwhile clean up AHP Pro by emptying deleted macros from the recycle bin (and save the file that way?).
3) Plug the interface back in without the batteries and re-connect (preferably to an AHP with an empty file and nothing in the recycle bin?).
4) Purge Delayed Macros (requires interface) and clear interface memory.
5) Repeat Steps 1 through 4 (except that batteries are still out -- this may be overkill...).
6) Make sure the AHP recycle bin is empty and clear interface memory again.
7) Set up hardware configuration and update interface.
Eight) Download timers and macros.
9) Install batteries and then disconnect from computer. Move interface to desired A/C outlet.
(I only noticed this failure because I realized I had forgotten to reset the battery counter in the hardware configuration, so I though I would reconnect to do so.)
Note that the USB did not fail
during the procedure above.
My re-connection procedure is complicated by the fact that I cannot just connect the USB directly because the wall outlet I'm using is too far from the computer. Here is the procedure I use (which didn't used to cause problems):
A) Unplug interface from A/C outlet (batteries still installed).
B) Hook up an extension cord to outlet and plug interface into that.
C) Connect USB to computer; USB connection fails as described at beginning of this thread.
I see three possibilities:
1) I didn't execute your reset procedure properly (see steps 1-9 near the beginning of this message).
2) Something I did after that procedure caused the problem (see steps 9 in first sequence and A-C immediately above).
3) There is actually a hardware problem in the CM15A, perhaps a deteriorating USB handler.
