I really do appreciate it. It's possible that this device is using high speed because it offers a feature to transfer its internal clipboard to the host, and it allows that clipboard to contain lots of data. Interestingly, though, hidden within a usage note, they do observe that, so far, they've been unable to achieve a transfer speed faster than 5,000 characters in seven minutes. It looks to me like this is exactly due to their incorrect setting of bInterval. :-) I've sent them a note about it. -- Dave Mielke | 2213 Fox Crescent | The Bible is the very Word of God.
