This happens with both my usb printers (epson stylus color 740 and canon hl 1250) I see this kind of message if it happens with dmesg: <snip> bootsplash: status on console 0 changed to on drivers/usb/class/usblp.c: usblp0: nonzero read/write bulk status received: -71 usb 4-1: clear tt 1 (1041) error -71 hub 4-0:1.0: port 1 disabled by hub (EMI?), re-enabling... usb 4-1: USB disconnect, address 2 usb 4-1.1: USB disconnect, address 3 usb 4-1.1.1: USB disconnect, address 7 usb 4-1: clear tt 1 (8040) error -19 usb 4-1.2: USB disconnect, address 4 drivers/usb/class/usblp.c: usblp0: error -71 reading printer status usb 4-1.3: USB disconnect, address 5 usb 4-1.3.1: USB disconnect, address 8 usb 4-1.4: USB disconnect, address 6 drivers/usb/class/usblp.c: usblp0: removed usb 4-1: new high speed USB device using ehci_hcd and address 9 usb 4-1: new device found, idVendor=05e3, idProduct=0608 usb 4-1: new device strings: Mfr=0, Product=1, SerialNumber=0 usb 4-1: Product: USB2.0 Hub usb 4-1: configuration #1 chosen from 1 choice hub 4-1:1.0: USB hub found hub 4-1:1.0: 4 ports detected usb 4-1.1: new high speed USB device using ehci_hcd and address 10 usb 4-1.1: new device found, idVendor=05e3, idProduct=0608 usb 4-1.1: new device strings: Mfr=0, Product=1, SerialNumber=0 usb 4-1.1: Product: USB2.0 Hub usb 4-1.1: configuration #1 chosen from 1 choice hub 4-1.1:1.0: USB hub found hub 4-1.1:1.0: 4 ports detected usb 4-1.2: new full speed USB device using ehci_hcd and address 11 usb 4-1.2: new device found, idVendor=04f9, idProduct=0007 usb 4-1.2: new device strings: Mfr=0, Product=0, SerialNumber=0 usb 4-1.2: configuration #1 chosen from 1 choice drivers/usb/class/usblp.c: usblp0: USB Bidirectional printer dev 11 if 0 alt 0 proto 2 vid 0x04F9 pid 0x0007 usb 4-1.3: new high speed USB device using ehci_hcd and address 12 usb 4-1.3: new device found, idVendor=05e3, idProduct=0606 usb 4-1.3: new device strings: Mfr=0, Product=1, SerialNumber=0 usb 4-1.3: Product: USB2.0 Hub usb 4-1.3: configuration #1 chosen from 1 choice hub 4-1.3:1.0: USB hub found hub 4-1.3:1.0: 4 ports detected usb 4-1.4: new low speed USB device using ehci_hcd and address 13 usb 4-1.4: new device found, idVendor=046d, idProduct=c50e usb 4-1.4: new device strings: Mfr=1, Product=2, SerialNumber=0 usb 4-1.4: Product: USB RECEIVER usb 4-1.4: Manufacturer: Logitech usb 4-1.4: configuration #1 chosen from 1 choice input: Logitech USB RECEIVER as /class/input/input8 input: USB HID v1.11 Mouse [Logitech USB RECEIVER] on usb-0000:00:1d.7-1.4 usb 4-1.1.1: new low speed USB device using ehci_hcd and address 14 usb 4-1.1.1: new device found, idVendor=046a, idProduct=0001 usb 4-1.1.1: new device strings: Mfr=0, Product=0, SerialNumber=0 usb 4-1.1.1: configuration #1 chosen from 1 choice input: HID 046a:0001 as /class/input/input9 input: USB HID v1.00 Keyboard [HID 046a:0001] on usb-0000:00:1d.7-1.1.1 usb 4-1.3.1: new full speed USB device using ehci_hcd and address 15 usb 4-1.3.1: new device found, idVendor=04a9, idProduct=2208 usb 4-1.3.1: new device strings: Mfr=64, Product=77, SerialNumber=0 usb 4-1.3.1: Product: CanoScan usb 4-1.3.1: Manufacturer: Canon usb 4-1.3.1: configuration #1 chosen from 1 choice lp: driver loaded but no devices found usb 4-1.2: USB disconnect, address 11 drivers/usb/class/usblp.c: usblp0: removed usb 4-1.2: new full speed USB device using ehci_hcd and address 16 usb 4-1.2: new device found, idVendor=04f9, idProduct=0007 usb 4-1.2: new device strings: Mfr=0, Product=0, SerialNumber=0 usb 4-1.2: configuration #1 chosen from 1 choice drivers/usb/class/usblp.c: usblp0: USB Bidirectional printer dev 16 if 0 alt 0 proto 2 vid 0x04F9 pid 0x0007 lsusb shows this; Bus 004 Device 024: ID 04f9:0007 Brother Industries, Ltd HL-1250 Laser Printer Bus 004 Device 023: ID 04a9:2208 Canon, Inc.

Any suggestions for a better workaround resolving #2 (i.e. remove ehci_hcd without losing essential usb functionality) are welcome.
