For example, we are able to reproduce some of the issues we have on the SheevaPlug (Marvel Kirkwood ARM) with the same combinations of hubs and USB sticks. Do you have another USB Host board available to try to see if your issue is reproducible across platforms? Are you able to list the hub and the USB Stick that you are using below? Is it reproducible across different hubs and sticks? For example, SMSC hubs tend to exhibit the problems far more than Genesys Logic hubs. I have no experience with Cypress hubs as to whether they perform any better or not. If you search the mailing list, I asked about the same issue some time ago. -- Damien
