There is a USB firmware standard called DFU (Device Firmware Upgrade) which quite a nunmber of devices use (eg Atmel WiFi, Ti USB Audio, etc). I have a USB audio device that uses it but I haven't had much luck getting the USB stack to reprobe the device after it's been reprogrammed (I have to pull the connector out enough that it disconnects the data lines but not enough to unpower it..) Unfortunatly it's hard to say if your device does DFU at all.. I would suggest pulling it apart and trying to find data sheets on the chips in it. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (FreeBSD) iD8DBQBB2fBj5ZPcIHs/zowRAg9CAJ92XfbRJR0t7/6EVmVjqn4IgexQvgCfY0QR 5Tf9DA1odYCILf26t2bTAPQ= =BYjV -----END PGP SIGNATURE-----help
