.SH "DESCRIPTION"
.PP
This hands the URB from HCD to its USB device driver, using its completion function\&. The HCD has freed all per\-urb resources (and is done using urb\->hcpriv)\&. It also released all HCD locks; the device driver won\*(Aqt cause problems if it frees, modifies, or resubmits this URB\&.
.PP
If
\fIurb\fR
was unlinked, the value of
\fIstatus\fR
will be overridden by
\fIurb\fR\->unlinked\&. Erroneous short transfers are detected in case the HCD hasn\*(Aqt checked for them\&.
