Up Studio no longer sees Mk II usb connected

[ZombiEd]

For some reason, Up Studio no longer sees my Cetus Mk II connected by USB. Fortunately I can access it through wireless but sometimes even looses that saying printer not connected. I have to go back and add every time I want to print something.

Anyone else seen this problem? I suspect there may be a Windows 10 updated causing it but can't confirm.

Dear Customer,

Which UP Studio version you use?
Please check the computer device manager to see if there is a missing software driver.

Have a look in the Windows Device manager to see if the printer has issues with the drivers?

I'm running UP v2.6.20.627

In the Device Manager there is a driver problem. Even though it sees it as Cetus S7(NL) it's an Unknown device and and a popup says: No driver files are required or have loaded for this device.

The only device drivers I found are on the Tiertime site but don't appear to be the correct ones since Windows doesn't see it to load it when doing an update driver.

If you open the unknown device, and look at the properties, the details tab will have a pull down where you can select hardware id.

List the VID and PID for the unknown device? Or proceed to open the .inf file in the provided drivers and see if you can find a matching section. Alternatively change the .inf file to match your device and try again (this may not work if the drivers are signed, but verifying the VID an PID is still usefull)

I'm seeing the following for the VID: USB\VID_4745&PID_277F&REV_0100
Under events: 3/24/2019 4:58:48 PM Device configured (oem51.inf)
Driver Management concluded the process to install driver winusbfm.inf_amd64_74964b4fa4eea4d5 for Device Instance ID USB\VID_4745&PID_277F\70172542 with the following status: 0x0.

Then on April 10: Device USB\VID_4745&PID_277F\70172542 was not migrated due to partial or ambiguous match.

In trying to install the driver I get: Windows found drivers for your device but encounter and error wile attempting to install them
3D Printer@FreeMotion
A Problem was encountered wile attempting to add the driver to the store

I was able to get a VID, how do I verify it is correct.

Its listed inside the driver .inf file, but what you listed does match a entry there. Thats kind of good news, most likely printer is working, and identifies itself correctly to the computer.

But you're obviously still having issues with Windows. The usual remedies include disconnect the device, removing all driver files, rebooting and trying again.

look for
WdfCoInstaller01009.dll
WinUSBCoInstaller2.dll
winusbcoinstaller2_chk.dll
winusbfm.cat
WinusbFM.inf

Sorry I can't be of more help with windows 10, hopefully Tiertime will be able to provide further assistance.
