6 :Revised: 2004-Oct-21
20 Non-USB-specific:
26 ``-ENOMEM``	no memory for allocation of internal structures
29 USB-specific:
32 ``-EBUSY``		The URB is already active.
34 ``-ENODEV``		specified USB-device or bus doesn't exist
36 ``-ENOENT``		specified interface or endpoint does not exist or
39 ``-ENXIO``		host controller driver does not support queuing of
42 ``-EINVAL``		a) Invalid transfer type specified (or not supported)
48 ``-EXDEV``		ISO: ``URB_ISO_ASAP`` wasn't specified and all the
52 ``-EFBIG``		Host controller driver can't schedule that many ISO
55 ``-EPIPE``		The pipe type specified in the URB doesn't match the
58 ``-EMSGSIZE``		(a) endpoint maxpacket size is zero; it is not usable
64 ``-ENOSPC``		This request would overcommit the usb bandwidth reserved
67 ``-ESHUTDOWN``		The device or host controller has been disabled due to
70 ``-EPERM``		Submission failed because ``urb->reject`` was set.
72 ``-EHOSTUNREACH``	URB was rejected because the device is suspended.
74 ``-ENOEXEC``		A control URB doesn't contain a Setup packet.
77 Error codes returned by ``in urb->status`` or in ``iso_frame_desc[n].status`` (for ISO)
88 For isochronous URBs, the urb status value is non-zero only if the URB is
92 should only see ``urb->status`` set to zero, ``-ENOENT``, ``-ECONNRESET``,
93 ``-ESHUTDOWN``, or ``-EREMOTEIO``. Individual frame descriptor status fields
100 ``-ENOENT``			URB was synchronously unlinked by
103 ``-EINPROGRESS``		URB still pending, no results yet
106 ``-EPROTO`` [#f1]_, [#f2]_	a) bitstuff error
108 				   prescribed bus turn-around time
111 ``-EILSEQ`` [#f1]_, [#f2]_	a) CRC mismatch
113 				   prescribed bus turn-around time
123 ``-ETIME`` [#f2]_		No response packet received within the
124 				prescribed bus turn-around time.  This error
126 				``-EPROTO`` or ``-EILSEQ``.
128 ``-ETIMEDOUT``			Synchronous USB message functions use this code
133 ``-EPIPE`` [#f2]_		Endpoint stalled.  For non-control endpoints,
137 ``-ECOMM``			During an IN transfer, the host controller
141 ``-ENOSR``			During an OUT transfer, the host controller
145 ``-EOVERFLOW`` [#f1]_		The amount of data returned by the endpoint was
146 				greater than either the max packet size of the
147 				endpoint or the remaining buffer size.
150 ``-EREMOTEIO``			The data read from the endpoint did not fill
152 				was set in ``urb->transfer_flags``.
154 ``-ENODEV``			Device was removed.  Often preceded by a burst
158 ``-EXDEV``			ISO transfer only partially completed
160 				not ``urb->status``)
162 ``-EINVAL``			ISO madness, if this happens: Log off and
165 ``-ECONNRESET``			URB was asynchronously unlinked by
168 ``-ESHUTDOWN``			The device or host controller has been
177    Error codes like ``-EPROTO``, ``-EILSEQ`` and ``-EOVERFLOW`` normally
190 Error codes returned by usbcore-functions
198 ``-EINVAL``		error during registering new driver
206 ``-ETIMEDOUT``		Timeout expired before the transfer completed.
