6104BC stopped working

Sakis

Hello everyone, i have bought a 6104bc oscilloscope, about a couple of years ago. Recently it stopped working, not recognised by the pc. despite having it for about 2 years i didnt put much hours of work into it, i don't really need it often but when i need it, i need it. i have an analog scope, multimeters etc but a digital oscilloscope is in some cases necessary to do the troubleshooting. Except for this problem i found this oscilloscope to be perfect.
now some more details that may help you, help me.
there is enough power provided to the scope by 2 usb 3.0 ports, or 2 usb 2.0 ports (voltage still reads 5volts on the scopes pcb either way)

the front tht led (red/green) is now always off.
the smd yellow led in the pcb (only visible with the cover off) will turn on for about 2 seconds after powering the scope and then off again.
thanks in advance for any help.

thanks for the fast reply, however i tried it on 3 different computers and none of them will recognise it.
tried it with both the old drivers and the new.

i get this on the device manager, regardless of which driver is installed and windows won't accept any of the drivers as valid for this device

i suspect it to be a flash U17 issue like a similar problem on the forums:

however mine doesnt wake up with hot air, maybe it will if i try actual soldering temperatures but for fear of further damage i didn't go above 100c for couple of seconds.
As for the "yellow" led on-duration it may be 1 second maybe 2 or 3, would that make a difference?
