Ok, so I've recently built a PC & my USB ports don't seem to be able to power my scanner (Canon Lide 220) consistently. Basically, everytime I try to scan (via Scangear software), the scan hangs or disconnects halfway.
My hardware specs are the following (let me know if any other spec might be useful to know):
- Intel i5 8400
- Asus TUF Z390-Plus Gaming
- 2*8 Go DDR4
- PSU Seasonic Fanless 520W
- Windows 10 build 1809
- 1 NVME drive
- 1 SATA HD
- Palit RTX 2060 Pro Gaming OC
- 3 Chassis Fans + 1 CPU Fan
- 1 Logitech USB mouse + keyboard dongle
- 1 Xbox controller
My PSU should be more than enough to provide for the entire system.
here are the steps that I have taken to try to solve the problem (nothing worked...):
- Try the scanner on another computer (it works fine)
- Rebooted the computer
- Try different USB ports on my computer (both MB + chassis)
- In the Device Manager:
- Verified the USB drivers (they are all up to date)
- uninstalled the USB components one by one in the device manager and have windows reinstall everything
- unchecked the power management to "allow the computer to turn off this device to save power" for each USB device
- Changed the USB selective suspend to disabled
- I used the Windows USB Troubleshooter to no avail...
- Verified the MB connections (they're fine)
As a sidenote, I do not have any problem using the XBOX controller and the mouse+KB dongle. I did notice, though, that my keyboard (a Logitech K800) was not charging properly through USB (it starts charging but stops after a few seconds). This is what makes me think the USB is somehow not providing enough power.
I'm at wits end with this issue & I can't seem to find the source of the problem.
Any help would be greatly appreciated.
