Hi Randy.

Sorry I didn't catch your reply, for some reason my mailclient didn't order
it correctly.

Anyway, I'm no kernel guru. I hope this is what you wanted:

- I started with boot: Linux debug
- The var/log/messages file did not register anything strange, just
the correct registering of the printer
- the var/log/syslog says:

Oct 4 11:21:14 on6jc kernel: hub.c: already running port 2 disabled by hub (EMI
Oct 4 11:21:25 on6jc kernel: hub.c: already running port 2 disabled by hub (EMI
Oct 4 11:21:25 on6jc kernel: printer.c: failed reading usblp status

I have the impression that the EMI message is wrong. I get this message each
time I boot (In fact, the first line - at 11:21:14 - was the message at boot.
The second line is when the print daemon awakens)

- var/log/debug says:

Another indication: On advice of someone who replied privately to my mail:
I tried to print to a file, the cat file > /dev/usblp0, and this has yet to
fail - no apparent problems there. It even seems to print a lot faster.

Thanks for replying!

John

BTW: The printer is a HP 810C.
