HP Deskjet 648C using USB won`t work
Hi,
I've an HP Deskjet 648C printer. There are both parallel and USB interfaces on the printer. I've been using it on the parallel interface using CUPS. I now want that parallel interface for a parallel only printer. The Deskjet I want to move to USB.
The printer works fine in Ubuntu 5.10, but it is not detected in Debian 3.1, lsusb shows nothing. So I can`t even get to configuring it in CUPS.
Might this be related to a USB expansion card I added a while back. Before that, the only USB was the USB1.1 on the mother board. I was running a USB scanner fine with a USB 1.1 connection. However, since installing the expansion card to get USB 2.0, the scanner has been undetectable under Debian 3.1, but is detected by Ubuntu 5.10.
I have everything in the kernel, I think. The expansion card works fine; I regularly use a card reader and USB pen-drives in it. I've also compiled in support for USB printers. Anyone know any documents I can read to help solve this? I don`t seem to be able to find much of use on the 'Net when I've googled for usb printing problems under Linux.
Any suggestions welcome.
Thanks.
