Windows 10: Keyboard Detected as Unspecified Devices

Hello! Instead of being identified as a USB keyboard under the Devices in the Control Panel, a magnetic switch keyboard of mine is under Unspecified as a "USB Input Device." Do you have any idea what is causing this? How can I fix it? I am currently using an E-Yooso HZ-68 Keyboard. When I first plugged it in, it just worked fine, but when I tried to download the software to adjust the rapid trigger, it suddenly didn't work.

Zebra thermal printer KR203 being detected as unspecified device, not as printer.

We have multiple KIOSK systems connected to Zebra KR203 printer. The printer used to work with Windows 10 1909 update but with the security updates (20h2 or 21h1), printer stopped working.

We performed below steps to create a driver which can support Zebra KR203 printer. Please suggest if we are missing something.

• We setup a development machine to work on this issue and installed Visual Studio 2019 and Windows Driver Kit Version 10.0.19041.685.
  
• Uninstalled pre-installed Zebra printer driver.
  
• Created a new project of type “V4 printer driver” on VS2019.
  
• In the Create a V4 Print Driver Wizard, under Choose the driver rendering type:, selected V4 print driver with custom rendering filters (accepts XPS only). Kept other setup settings as default. After project is created, verified the necessary files after the creation of project as suggested by document. Followed the steps from the link: https://docs.microsoft.com/en-us/windows-hardware/drivers/print/building-a-basic-v4-printer-driver
  
• Configured the target machine as per “Configure the driver solution for debugging and deployment” steps provided. Result: Complete
  
• We are currently in “Build and deploy the driver” step of the link mentioned above. Result: Builds successfully but driver output states “please select a valid target machine for deployment from the project property page”.
  

NOTE:

One day the printer started giving prints from MS word (windows 10 20H2 version), which was not working earlier. We tried to test the printer on another system following the same steps, but when we again connected the printer back to development machine, it stopped working and now it is not being detected as a printer, rather being detected as an unspecified device. (with or without Zebra’s own drivers)

 

How can I get Windows 10 to recognize an Unspecified Device as a Printer?

I have installed a DYMO printer, but it is not listed as a printer but only as an Unspecified Device. How can I get Windows 10 to recognize an Unspecified Device as a Printer? All printer troubleshooting steps require it to be listed as a Printer, and
all Help solutions assume that it can be recognized as a printer.

 

Cant delete an unspecified bluetooth device

Hi JakeOrElwood,

Is "unspecified device" limited to Logitech K380?

Is it the same after enabling "Allow Bluetooth devices to find this PC"?

Is it the same after installing drivers and software for the K380 Multi-Device Bluetooth Keyboard?
