Update. So after fiddling with this for a few days... If I boot up my system, and *then* plug in the reader, it reads correctly until I exit my application. (I've now switched over to syncSubmit(byte[]), which works great.) Afterwards, if I launch it again, it doesn't read anymore, but I have to unplug and plug in the device again. I close the pipe and release the interface correctly, I think.
I'm trying to send a RESET_DEVICE, maybe that would take care of things, but I think I'm having trouble translating the HID Set_Report.
