Why not use just a small pool of URBs, and resubmit each one as it completes? Laszlo, it's clear from the trace where the problem first occurs. The device stops responding in the middle of the first WRITE command. Maybe, as Oliver guessed, it doesn't like to receive a lot of commands all at once. Or maybe something went wrong during the write. Oliver's test patch should help determine what happened.
