Hi,

After MUCH browsing, and scouring of documentation regarding USB on a 18F2550 and attempting to use EASYHID to communicate, I have finally found a tool that scans for the vendorID and productID and returns an 'access is denied' error.

My problem was that the device enumerates on the bus, but I cannot exchange data, despite posts in these forums saying that people have been successful.

I've read that windows reserves access to mouse and keyboard for itself and now I'm totally confused...

The 18F2550 sends information to the PC declaring itself as "PIC18 USB Mouse".

If windows reserves access to this device, how on earth can I send and receive data?

Help...
