    In some cases, I did. In other cases, I did not. Here are some "greatest
    hits... and I was also turning printers on and off and changing cables
    and testing different USB ports, so this first batch of log messages
    could correspond to those types of changes:

    Feb 27 10:52:11 [kernel] drivers/usb/class/usblp.c: usblp0: off-line
    Feb 27 10:52:44 [kernel] drivers/usb/class/usblp.c: usblp0: error -71 reading printer status
    - Last output repeated 1140 times -
    Feb 27 10:52:45 [kernel] usb 1-4: USB disconnect, address 9
    Feb 27 10:52:45 [kernel] drivers/usb/class/usblp.c: usblp0: error -71 reading printer status
    Feb 27 10:52:45 [kernel] drivers/usb/class/usblp.c: usblp0: removed

    Then when I was doing my initial testing with the Epson Stylus Photo 960
    and the escputil program (as well as catting printer data directly to
    the printer,) I saw a bunch of stuff like this:

    Feb 27 10:30:30 [kernel] usb 1-4.3: new full speed USB device using address 11
    Feb 27 10:30:30 [kernel] ehci_hcd 0000:00:02.2: qh c1b91700 (#0) state 1
    Feb 27 10:30:30 [kernel] drivers/usb/class/usblp.c: usblp0: USB Bidirectional printer dev 11 if 0 alt 0 proto 2 vid 0x04B8 pid 0x0005
    Feb 27 10:31:01 [kernel] drivers/usb/class/usblp.c: usblp0: on fire

    Specific symptoms were not having the printers respond to an escputil
    (Epson printer utility from gimp-print) head cleaning run. On the laser
    printer, data would get to the printer, but seemingly slowly, and I'd
    need to hit the "go" button on the printer to get the sheet to print
    rather than have the printer print on its own. It seems that both
    printers did not get the full amount of data that they were expecting,
    and either didn't respond at all or didn't complete the print job
    without manual assistance.

    The problems with the laser printer didn't generally produce any log
    messages. Those with the Epson (particularly escputil) generally did.

    With 2.6.3-bk9, I also had a block of two mainboard USB ports simply
    stop functioning -- to the point of even no longer sending power to the
    USB hub that I was using.

    Hope that helps and let me know if you need any more info,
