Hi,
USB\VID_09FB&PID_6010&REV_0142&MI_00 looks suspicious. It's not listed in usbblasterii.inf shipped with recent Quartus versions. You may check which oem.inf file is linked with this device instance and post its content here.

My old Blaster 1 is:

USB\VID_09FB&PID_6001&REV_0400
USB\VID_09FB&PID_6001

with driver from: C:\altera_pro\25.1.1\quartus\drivers\usb-blaster\usbblstr.inf

Blaster II is:

USB\VID_09FB&PID_6010&REV_0142&MI_00
USB\VID_09FB&PID_6010&MI_00

with driver form: C:\altera_pro\25.1.1\quartus\drivers\usb-blaster-ii\usbblasterii.inf

I do not know why the REV_XXXX is there when the INF file doesnt contain it. 

Both blasters are stable in the device manager but both fails with the Quartus and Agilex 5 board. They can load board 1x or 2x,.. but frequently the Blaster II changes to the variant (in the Quartus programmer hardvare list) and do not work more. The old Blaster simlpy diappears from the Quartus programmer hardware list.
