sudo usbhid-dump -s 1:3 -f -e stream

From the manual we get what the parameters mean:

 -s =bus[:dev]

Replace -s 1:3 with the Bus Device for your device

Output is in the form

BUS:DEVICE:INTERFACE:ENTITY TIMESTAMP

.001:003:000:STREAM             1667902900.482858

 00 00 00 FC FF 00 00

.001:003:000:STREAM             1667902900.490787

 00 00 00 FE FF 00 00

.001:003:000:STREAM             1667902900.498863

 00 01 00 FC FF 00 00

Timestamp is in seconds before the point and subdivisions of seconds after the point.
First 3 digits milliseconds next 3 digits microseconds.
So the difference between two events is in my case is 8ms.

Note the speed dpi choise does not affect this. This is the maximum physical transmit speed.

usbhid-dump will disconect you mouse/device.
if you mess up just remove the receiver and plug-it back in or wait 60 seconds.

It is a WiFi Evoluent Vertical Mouse 4.
