The USB trace shows the URBs I'm interested in (0003-0024), but doesn't print the requests and trims data after the first 8 bytes of data. I will need the full request (bRequestType, bRequest, wIndex, wValue and wLength fields) and all data (26 bytes). You can cut the trace after the first successful "Isoch Transfer", this will help keeping the attachment size low and making the mailing list engine happy (don't worry if the e-mail is a bit bigger than the 40kB limit, I can approve it manually).
