Hi
I was wondering if anyone knew what would be the source of a
ehci_hcd 0000:01:0b.3: devpath 1 ep0out 3strikes
hardware error. I traced this output to
/usr/src/linux-2.6.16.9/drivers/usb/host/ehci-q.c int the code segment
/* serious "can't proceed" faults reported by the hardware */
if (token & QTD_STS_HALT) {
if (token & QTD_STS_BABBLE) {
/* FIXME "must" disable babbling device's port too */
urb->status = -EOVERFLOW;
} else if (token & QTD_STS_MMF) {
/* fs/ls interrupt xfer missed the complete-split */
urb->status = -EPROTO;
} else if (token & QTD_STS_DBE) {
urb->status = (QTD_PID (token) == 1) /* IN ? */
? -ENOSR /* hc couldn't read data */
: -ECOMM; /* hc couldn't write data */
} else if (token & QTD_STS_XACT) {
/* timeout, bad crc, wrong PID, etc; retried */
if (QTD_CERR (token))
urb->status = -EPIPE;
else {
ehci_dbg (ehci, "devpath %s ep%d%s 3strikes\n",
urb->dev->devpath,
usb_pipeendpoint (urb->pipe),
usb_pipein (urb->pipe) ? "in" : "out");
urb->status = -EPROTO;
}
Is this error produced by the usb device, or the USB2.0 pci host card I
am using. I've compared my dmesg output when the device is connected to
the card and using ehci, to when it's connected to the card, but using
ohci. The setup progress is the same until ehci encounter's the devpath
1 ep0in 3strikes error. Can anyone shed some light on this please.
