Is then a patch for device gadget, no? (at the moment, we are using Kernel 2.4.20 there). Or a patch for host computer? (yesterday I tested with 2.6.12). Do you remember if is this patch? http://sourceforge.net/mailarchive/message.php?msg_id=9403210 (or if you remember aprox. date, Kernel version, author, subject or something like to me. I have been searching using khubd timed out on ep0in strings without 100% success) Thank you very much, I hope that soon I will be able to help somebody from list :-) -- Carles Pina i Estany GPG id: 0x8CBDAE64 http://pinux.info ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf _______________________________________________ linux-usb-devel@lists.sourceforge.net To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
