Hi to all and thank you for accepting me here .
Recently y have brought an usb dso-2100 2ch and seems not to work ,the led does not blink .Checked some voltages on the pcb and are present 5v ,3,3 and 2,47(2.5) reference.
The regulator 3.3v its warm ,not very excessive and also a little bit the xilinx .
When y plug to the usb port it is recognized and y can install drives .
Any help it will be appreciated .
