I have a Willem programmer GQ-3X since august 2010 and worked good until yesterday. I read eprom M27C256B, i've removed the IC from the socket and the USB. After a while i wanted to read another eprom and the software remained freeze, i've removed the usb and tried again, the same thing. After a few minutes USBPrg returned the error "Hardware out of sync! Please re-connect the programmer.". I did that and still the same problem.
