usb device not recognized
This has happened several times recently. Message refers to printer - Brother HL-2240. Turning it off and on doesn't return it so service. I assume I'll have to restart computer. The message occurs after computer is on for several hours. Anything I can do? Suggestions welcome. TIA -- I love a good meal! That's why I don't cook. |

Tried setting there for offline printing but despite three documents that didn't happen. -- I love a good meal! That's why I don't cook. |

I ended up putting mine on a network adapter. |

How long is the cable and have you tried another one? These printers don't like repeater cables much. I ended up putting mine on a network adapter. Probably 6 - 10' long. They are about 4' apart on my deck. This worked fine for many years until recently. I'll try to dig out the cable and replace it. Is there any way to return the printer to life when this happens without the long annoying process of shutting down and restarting the computer and XL? TIA I found one way. Unplug and replug USB cable. XL then reinstlls printer and it works. Pretty quick but probably not a good thing to keep repeating. You can buy a "USB switch", which has like 1 input and 2 outputs. The concept of the device, is it was invented to allow one printer to be shared with two computers, and the "button" on the top flips the selector. Since each "flip" of the electronic box represents a re-insertion, it takes the place of unplugging and re-plugging the cable. Press the button twice, returns the configuration to the original state, but the OS thinks the printer has been unplugged and re-plugged. They come in 1 print to 2 computers, 1 printer to 4 computers, 4 printers to 2 computers and so on. Usually the button on top is flimsy (now, who would have guessed that, from China and all). But if you wanted an alternative, that's the only one that comes to mind. KVM boxes have wiring in that sort of shape too, but I don't know how you'd (ab)use a KVM to achieve the same end. The switch device is also a lot cheaper than a KVM, so it's no contest there. Now, let's see if they still make them. I select one at random. https://www.newegg.com/rosewill-rcus...82E16812119894 One review says "cheap button", so at least it's consistent with industry norms. Looks "pretty" here. Presentation is everything. https://www.rosewill.com/product/rcu...#tab-downloads This picture shows the logical representation. That's why I went looking for a manual, to see if they'd explain it. It switches up to four peripherals, between two computers, but your printer would be plugging into the four port box and using only one of the ports. https://images10.rosewill.com/rosewi.../module_03.png This would be how you'd wire it up. Note - if a USB peripheral is bus powered, it *may* need to have a +5V supply plugged into the LED box. However, you're running a printer, and a lot of them have their own AC cord, in which case practically zero power will be drawn from Computer #1 connector. If you put four USB disk drives off the bottom of this box, it would need a *ton* of power. Don't do that :-) Computer #1 Male connector X | | | | Switch box top side cables ----------- cable_with_big_button | | | | | X X X press button twice with 3 seconds printer delay between each press. The computer to female needs time to "lose" and "gain" the port on peripheral! LED box HTH, Paul |

TIA I could kick start mine most of the time by moving the cable to the next USB port. It would reload the driver and work for a while. |

I don't think I've seen _any_ *printer* that runs from the USB 2½ watts. I have seen (_very_ expensive!) portable printers intended for travelling salesmen, but I _think_ they have always had either their own PSU or contained something rechargeable.
