This is with both the usb-uhci and the uhci drivers. There have been some "interesting" discussions about HP printers on the linux-usb-devel mailing list :) A very simple patch that might work for you is at: http://marc.theaimsgroup.com/?l=linux-usb-devel&m=101338636901219 while a more "correct" patch is at: http://marc.theaimsgroup.com/?l=linux-usb-devel&m=101366701613394 Please let me know if either of these patches fix your problem. thanks, greg k-h
