In order to do this in libhid, you need different Usage IDs for each report. I was under the impression that the Usages for each report had to be unique, but I could be wrong about that. > For my device I am supposed to find an appropriately sized report > and use that report for the message that I want to send.

It's going to take more work to make libhid work with this device than it would to simply use the underlying libusb calls directly in your code (by hardcoding the parameters for a given report ID). Hint: you don't need hidparser/ at all for this, and most of what you need is in hid_exchange.c _______________________________________________ libhid-discuss mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/libhid-discuss http://libhid.alioth.debian.org/
