>Description:

The various bits of dmesg output related to the printer are:  

pci0 at mainbus0 bus 0: configuration mode 1
pci0: i/o space, memory space enabled, rd/line, rd/mult, wr/inv ok

ohci0 at pci0 dev 1 function 2: Silicon Integrated System 5597/5598 USB host controller (rev. 0x07)
ohci0: interrupting at irq 9    
ohci0: OHCI version 1.0, legacy support

usb0 at ohci0: USB revision 1.0 

uhub0 at usb0
uhub0: Silicon Integra OHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub0: 3 ports with 3 removable, self powered 

ulpt0 at uhub0 port 1 configuration 1 interface 0 
ulpt0: Compaq Corporation Compaq A1500, rev 1.10/1.00, addr 2, iclass 7/1
ulpt0: using bi-directional mode


If I unplug the USB cable to the printer I see ulpt0 detach in the 
console messages.  If I plut the USB cable back into the printer,
I see the ulpt0 attach message.  If I unplug the printer power
cord I see the ulpt0 detach message and if I plug the printer power
cord back in, the machine wedges hard.  It will not respond to
the keyboard or pings over the network.

	
>How-To-Repeat:
