Commit e56e69cc0ff4 ("usb: gadget: net2280: Use pr_* function") is
included in today's linux-next (ie, next-20140704).
It contains this odd chunk:
@@ -1566,7 +1563,7 @@ static const struct usb_gadget_ops net2280_ops = {
/*-------------------------------------------------------------------------*/
-#ifdef CONFIG_USB_GADGET_DEBUG_FILES
+#ifdef CONFIG_USB_GADGET_PDEBUG_FILES
/* FIXME move these into procfs, and use seq_file.
* Sysfs _still_ doesn't behave for arbitrarily sized files,
(Commit b7ca96655ddd ("usb: gadget: Gadget directory cleanup - group UDC
drivers"), also included in today's linux-next, moved that new check for
CONFIG_USB_GADGET_PDEBUG_FILES to drivers/usb/gadget/udc/net2280.c.)
Using CONFIG_USB_GADGET_PDEBUG_FILES appears to be just an editing
mistake. Would Ricardo like to submit the trivial patch to clean it up
or should I do that?

My fault. Thank you very much for reporting it. I have just posted the patch

Hi
I have a raspberry PI sending its console to my box via a pl2303
[ 5.184385] usbserial: USB Serial support registered for pl2303

[ 5.185353] usb 1-2.6: pl2303 converter now attached to ttyUSB0
and with the latest fixes from git on 3.16 its now started spamming my logs with:

What exact pl2303 is this? Can you provide the output from 'lsusb'?

That's saying there was one of the following errors in this device:
a) bitstuff error
b) no response packet received within the prescribed bus turn-around
time
c) unknown USB error
All of which point to either a problem in the USB host controller, or
the usb device itself.
Is this an "unpatched" 3.16-rc kernel running on the rpi? If so, odds
are it's a host controller issue...
thanks,
greg k-h

Hi,
The kernel in question is running on a i7 with a pi connected via to the i6 via the pl2303 to view the pi's console.
The kernel on the i7 is at level:
commit 77c4cf17ae867ba93233b3832bda3de7adaae326

There is one extra patch applied to fix a problem with the boot stalling
