Dear Maintainer,
The Keyspan USB serial adapter USA-49WLC fails to load firmware and
will not work. This device is based on an older generation
Cypress EZ-USB FX (CY7C64613-80NC). The firmware fails to load when
the device is attached. While searching for an answer I found
the problem may stem from a non-standard implementation of the
firmware loading commands. Earlier versions of the kernel
(pre-Wheezy) did work with this device. I have tried but have been
unable to locate the change in the USB code taht causes this
failure.
[...]
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.
Ben.
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.
