I've got a fingerprint scanner: Finger Print FP-2000U Manufacturer: JEIL DATA SYSTEM CORP. Vendor Id: 0786 Product Id: 0010 1 config 1 interface with 3 alternate numbers 1 endpoint The endpoint is a isochronous in (1ms), which has a max. packet size of 0, 150 or 200 bytes depending on alternate number. When using sniffusb 0.12: 1) The fingerprint scanner using application does stop to work properly. 2) I see that the driver selects anternate 1 with a packet size of 200. It requests 10 of these packets and apparently receives the 2000 bytes, but sniffusb shows me only 624 bytes. So far I got nothing recognizable out of these bytes. What would be the quickes way to get information how it works and how to verify this. libusb does apparently not support isochronous transfers.
