Yes, it's definitely still broken. I knew that and I
expect that at least KHK & Stephen Gowdy know it also.
I'll apply your 1-hour timeout patch [as a workaround],
but I really believe that there should not be a timeout
associated with the printer reporting an error.
[I could be printing an important <something> overnight
and have a printer error. I'd like to be able to fix
the printer error and resume printing when I find the
problem the next morning -- not start the whole thing
over again.]
A timeout on USB transfers is fine, but once the bulk
transfer times out, the driver should notice that the
printer is {off-line, out-of-paper, on-fire} and then
just wait.........a long time, if needed,
until that error condition goes away or the user kills
the printing program => usblp_close().
Of course, one (other) problem with this is that the
USB printer driver and HCD may have successfully
transferred all of the data to the printer, gone thru
usblp_close(), and the printer has lots of data
buffered, when the printer has an error and there's
nothing on the host that knows or cares about this,
but I don't know how to solve this one.
Anyone is welcome to submit patches on this. I'll get
back to it one of these days.
