I took that literally. So, in an effort to control the enumeration of the printers, I blacklisted 'parport' and rebooted. Didn't help as the one printer discovered was still usblp2, and the parport and friends still appeared in an lsmod. So I blacklisted the rest of the parports friends, ppdev and parport_pc and will reboot again, but before I do that again, is there a good explanation as to why I have to wait till the reboot is done, tail the log and unplug the long cable/hub that connects the stuff in the basement to an external usb-2.0 hub? Then when I reconnect the cable, 3 or 4 seconds later, this time the discovery finds everything down there: Sep 19 13:19:13 coyote klogd: usb 1-1.1: new full speed USB device using ehci_hcd and address 17 Sep 19 13:19:13 coyote klogd: usb 1-1.1: New USB device found, idVendor=03eb, idProduct=3301 Sep 19 13:19:13 coyote klogd: usb 1-1.1: New USB device strings: Mfr=0, Product=2, SerialNumber=0 Sep 19 13:19:13 coyote klogd: usb 1-1.1: Product: Standard USB Hub Sep 19 13:19:13 coyote klogd: hub 1-1.1:1.0: USB hub found Sep 19 13:19:13 coyote klogd: hub 1-1.1:1.0: 4 ports detected Sep 19 13:19:14 coyote klogd: usb 1-1.1.4: new full speed USB device using ehci_hcd and address 18 Sep 19 13:19:14 coyote klogd: usb 1-1.1.4: not running at top speed; connect to a high speed hub Sep 19 13:19:14 coyote klogd: usb 1-1.1.4: New USB device found, idVendor=0409, idProduct=0059 Sep 19 13:19:14 coyote klogd: usb 1-1.1.4: New USB device strings: Mfr=0, Product=0, SerialNumber=0 Sep 19 13:19:14 coyote klogd: hub 1-1.1.4:1.0: USB hub found Sep 19 13:19:14 coyote klogd: hub 1-1.1.4:1.0: 4 ports detected Sep 19 13:19:14 coyote klogd: usb 1-1.1.4.4: new full speed USB device using ehci_hcd and address 19 Sep 19 13:19:14 coyote klogd: usb 1-1.1.4.4: not running at top speed; connect to a high speed hub Sep 19 13:19:14 coyote klogd: usb 1-1.1.4.4: New USB device found, idVendor=0409, idProduct=0059 Sep 19 13:19:14 coyote klogd: usb 1-1.1.4.4: New USB device strings: Mfr=0, Product=0, SerialNumber=0 Sep 19 13:19:14 coyote klogd: hub 1-1.1.4.4:1.0: USB hub found Sep 19 13:19:14 coyote klogd: hub 1-1.1.4.4:1.0: 4 ports detected Sep 19 13:19:14 coyote klogd: usb 1-1.1.4.4.3: new full speed USB device using ehci_hcd and address 20 Sep 19 13:19:14 coyote klogd: usb 1-1.1.4.4.3: New USB device found, idVendor=0403, idProduct=6001 Sep 19 13:19:14 coyote klogd: usb 1-1.1.4.4.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Sep 19 13:19:14 coyote klogd: usb 1-1.1.4.4.3: Product: USB HS SERIAL CONVERTER Sep 19 13:19:14 coyote klogd: usb 1-1.1.4.4.3: Manufacturer: FTDI Sep 19 13:19:14 coyote klogd: usb 1-1.1.4.4.3: SerialNumber: FTDHG43V Sep 19 13:19:14 coyote klogd: ftdi_sio 1-1.1.4.4.3:1.0: FTDI USB Serial Device converter detected Sep 19 13:19:14 coyote klogd: usb 1-1.1.4.4.3: Detected FT232BM Sep 19 13:19:14 coyote klogd: usb 1-1.1.4.4.3: Number of endpoints 2 Sep 19 13:19:14 coyote klogd: usb 1-1.1.4.4.3: Endpoint 1 MaxPacketSize 64 Sep 19 13:19:14 coyote klogd: usb 1-1.1.4.4.3: Endpoint 2 MaxPacketSize 64 Sep 19 13:19:14 coyote klogd: usb 1-1.1.4.4.3: Setting MaxPacketSize 64 Sep 19 13:19:14 coyote klogd: usb 1-1.1.4.4.3: FTDI USB Serial Device converter now attached to ttyUSB1 Sep 19 13:19:14 coyote klogd: usb 1-1.1.4.4.4: new full speed USB device using ehci_hcd and address 21 Sep 19 13:19:15 coyote klogd: usb 1-1.1.4.4.4: New USB device found, idVendor=04f9, idProduct=0033 Sep 19 13:19:15 coyote klogd: usb 1-1.1.4.4.4: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Sep 19 13:19:15 coyote klogd: usb 1-1.1.4.4.4: Product: HL-2140 series Sep 19 13:19:15 coyote klogd: usb 1-1.1.4.4.4: Manufacturer: Brother Sep 19 13:19:15 coyote klogd: usb 1-1.1.4.4.4: SerialNumber: L7J156867 Sep 19 13:19:15 coyote klogd: usblp3: USB Bidirectional printer dev 21 if 0 alt 0 proto 2 vid 0x04F9 pid 0x0033 Sep 19 13:19:15 coyote udev-configure-printer: invalid or missing IEEE 1284 Device ID Sep 19 13:19:16 coyote klogd: usb 1-4: usbfs: interface 1 claimed by usblp while 'usb' sets config #1 Sep 19 13:19:16 coyote klogd: usb 1-1.1.4.4.4: usbfs: interface 0 claimed by usblp while 'usb' sets config #1 Is there some reason this stuff is not found at bootup time? It is all plugged in and powered full time. The present kernal is pclos, version 2.6.38.8-pclos3.pae.bfs, where the bfs is Con's Brain Fuck Scheduler, and which works very very well for desktop use. udev is udev-168-6-pclos2011. Thanks for any advice regarding this. Cheers, gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
