Since I upgraded to the 2.3.99+ version of the USB system I am
experiencing problems with my USB connected printer. The printer
is an EPSON STC740. I'm trying to print one graphics page (does
not matter if in 1440dpi or 720dpi mode) and some time during
the page the USB sytem reports an error and the printer stops,
just sitting there and waiting for more data.
The following messages are from "dmesg" output:

This is with the printer.c from 2.4-test1 copied into the USB sytem
from 2.3.99-pre7 used as backport in a 2.2.15 kernel. I used the
2.4-test1 printer.c because I had similar problems with the 2.3.99pre7
version and I remembered some discussion about fixes in the printer
support since then.
Any advice? Any suggestions? Any fixes?
Thanks,
Karl Heinz
