help. USB drive isn't assigned a drive letter.

Any usb flash drive I plug into my computer isn't assigned a drive letter. The physical drive shows in the "safely remove hardware" but it doesnt show up in disk management. I have tried to populate the volume thru the safely remove hardware properties window and it does pop up in the list but it doesn't stay there. This isn't a format or assign a letter problem. It's more complicated then that. Maybe one of the services needed for usb drive management was disabled? Suggestions needed. btw external usb harddrives work fine.

Hi Lake,

Thank you for your response.

As per the description, I understand that the Epson device/program is not compatible with the USB 3.0.

I suggest you to connect it to the USB 2.0 and check if the same issue persists.

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:

• Right click on Start, and then click
  Run.
• Type devmgmt.msc and then click
  OK. Device Manager opens.
• Expand Universal Serial Bus controllers.

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

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