I am having trouble with configuring my Epson Photo 890 to print by the
USB port. This is on RH 9, fully up2date. Printer works fine under
whinedoze, so it is unlikely to be a hardware problem. The printer simply
isn't seen.
Modprobe printer doesn't change anything,

One thing I notice is that lsusb doesn't seem to show the printer, but
*does* show some odd bits - which file are the 'Unknown lines' in?:

The system doesn't seem to see anything attached to the hub:

Are there any other modules required or can anyone point me at a good
guide to USB printing. Failing that, I suppose I could always dig out the
old parallel cable :(
TIA
