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, Daniel
