Related dmesg translates to linux error -EXDEV propably caused by the following lines: <snip> static int uhci_result_isochronous(struct uhci_hcd *uhci, struct urb *urb) { struct uhci_td *td, *tmp; struct urb_priv *urbp = urb->hcpriv; struct uhci_qh *qh = urbp->qh; list_for_each_entry_safe(td, tmp, &urbp->td_list, list) { unsigned int ctrlstat; int status; int actlength; if (uhci_frame_before_eq(uhci->cur_iso_frame, qh->iso_frame)) return -EINPROGRESS; uhci_remove_tds_from_frame(uhci, qh->iso_frame); ctrlstat = td_status(td); if (ctrlstat & TD_CTRL_ACTIVE) { status = -EXDEV; /* TD was added too late? */ </snip> Karsten - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
