Is the firmware actually installed?  (It should be
/lib/firmware/keyspan/usa49wlc.fw, I think.)  We don't distribute
firmware for this device as it's not clear that we have permission to
do so.

The firmware is installed at:

/lib/firmware/keyspan/usa49wlc.fw

If I do the following:

1) Attach the device.

2) Use dmesg to confirm the load failure

3) Detach the device

4) Rename usa49wlc.fw to usa49wlc.fw.sav

5) Attache the device

I get this from dmesg.  I'm assuming the new error -2 indicates the file 
was not found.

Yes.  And the other error code (-110) indicates a time-out.

Can you test whether the attached patch fixes this?  You can do this by
following the instructions at
<https://kernel-handbook.alioth.debian.org/ch-common-tasks.html#s-common-official>.

Hi Ben,

That worked.  All four ports can now connect and communicate.  I haven't 
tested handshaking, hardware or software.

I did have to export "ezusb_writememory" from ezusb.c.

yes -- sorry for not being clear.  i was wondering whether the fix had
gone upstream, and if not, why not.
