weird USB problem: need help
I need to make a printing server using linux. The printer is a deskjet 3550, usb.
I have installed cups, ESP ghostscript, HPLIP and hpijs (official HP driver stuff). But it isnt working, i have a device_not_found error.
I use a USB mouse, and it works perfectly. If i unplug and plug my mouse again, this is what happens at /var/log/messages:
Mar 8 10:49:09 localhost kernel: usb 2-1: USB disconnect, address 5
Mar 8 10:49:11 localhost kernel: usb 2-1: new low speed USB device using uhci_hcd and address 6
Mar 8 10:49:11 localhost kernel: input: HID 1241:1177 as /class/input/input5
Mar 8 10:49:11 localhost kernel: input: USB HID v1.10 Mouse [HID 1241:1177] on usb-0000:00:1d.1-1
Weird thing is that: I plug and unplug my printer usb cable lots of times, on all usb slots, and there is no message at /var/log/messages. No changes at /proc/bus/usb/devices. I have even recompiled my kernel with built-in USB printer support and UHCI.
Anyone got any clue on why this happens? I dont know what else to do. Thanks.
