Is there a way to connect to the Bitsy over USB without ActiveSync?
I have tried, on Windows 2000, to use CreateFile to open a handle to the Anchor USB EZ-Link Cable, after successfully enumerating it with the SetupDi functions. But I get ERROR_ACCESS_DENIED. I have even created a SECURITY_ATTRIBUTES structure, but to no avail. USBView works to list it and to show its descriptors. (I wish I knew what USBView was doing.)
Also, once we are able to get a handle to the USB device on the PC, what do we have to do on the Bitsy? How do we communicate with the driver on the Bitsy side? I don't see any support for the SetupDi functions.

Okay, I figured out how USBView works (at least, functionally) and now can get a good handle from the PC.
Now I need to do the same thing on the Bitsy.
On the PC, I traverse host controllers (starting with \\.\HCn) and their hubs until I get to the Bitsy device. There is no \\.\HC0 on the Bitsy to do this with. What is the name of the device I pass to the CreateFile? |

Here's our problem.
We need to connect a Bitsy to a PC and have the PC send data to an application on the Bitsy. We have the PC side opening a pair of USB endpoints -- one for reading, and one for writing. We need to do the same thing on the Bitsy. The problem is that we can't see how to get a handle to the USB device on the Bitsy.
