Windows 10: USB Printer preventing computer from sleeping

My computer just will not sleep, either automatically or manually. I just disconnected each USB device one by one and found that it's the printer that's the culprit. There's no way in device manager to change the power setting for it to allow the computer to sleep. Can someone tell me how I can fix this? I have it attached to a USB hub. I tried connecting it directly to the PC, and it still won't sleep.

Windows 10 Version 1909, Build 18363.628
It's a Brother MFC printer

TIA!

printer usb is an older version

Hello,

Thank you for posting your query on Microsoft community. I regret the inconvenience caused to you. Let me help you.

• 
  What is the make and model of the printer and computer?
  
• 
  What is the exact error message?
  

I suggest you to disable and re-enable the USB controllers. The following steps will uninstall all the USB controllers and then re-install them:

a. Right click on Start, and then click
Run.

b. Type devmgmt.msc and then click
OK. Device Manager opens.

c. Expand Universal Serial Bus controllers.

Note: You might have to scroll down the list to find this item.

d. Right click the first USB controller under
Universal Serial Bus controllers, and then click Uninstall to remove it.

e. Repeat step 4 for each USB controller that is listed under
Universal Serial Bus controllers.

Note: Restart the computer. After the computer starts, Windows will automatically scan for hardware changes and reinstall all the USB controllers that you uninstalled.

If the issue persists then I suggest you to refer to the following article.

Hope the information helps. Please let us know if the issue persist and we will be happy to assist you further.

 

usb device not recognized (malfunction) - Printer

Hope somebody can help a non-techy here.
I have a canon IX4000 printer, and had been using it without problem. The next day (having touched nothing), I got a USB device not recognized warning, and that it has a malfunction (this is under Windows XP).

I've tried the following:
- deinstalling all USB drivers under device manager
- system restore to several days prior, when I knew the printer was working
- trying a different USB lead (tested the lead on another device, so know it works)
- plugged lead into every other available USB port on the computer (front and back).
- tried plugging it into another computer (comes up with the same malfunction warning)
- deinstalled the printer drivers, downloaded and reinstalled them.

Nothing I've tried works. I know the printer functions as I can start it up under service mode and print off test pages without problems, but my computer just won't have it. Could it be a hardware failure, and if not is there anything else I can try that isn't listed above?

Really grateful to anyone who can reply. *Smile
