Alligator Technologies USBPGF-S1

Before finding HIDmaker FS, I read everything I could about USB.  I understood the communication requirements, the report requirements, the enumeration process, the built in Windows support for HID, and more.  Yet, I had a tough time creating my own [PC program] and PIC firmware to match.  I probably spent 6 months of full-time effort to get to the point of having a marginally working single unit interface.  I needed to fulfill a multi-unit simultaneously operational real time interface.

By chance a colleague mentioned the Trace Systems product.  I invested about a week's worth of time with impressive results.  I had a working foundation for the successful completion of the entire requirement. The device was recognized by Windows the first time I plugged it in with the HIDmaker FS firmware running.

Granted, no product development effort is problem free, but at least our problems were not in the USB communication interface.  I just wish I had found HIDmaker FS before expending the first six months.
