    The most common failure on USB blasters in the output buffers chip. You can try and replace it. IIRC it is a 74LVC244

    Hi all, I have the same problem with my usb blaster rev C, I replaced the LVC244 but the usb blaster don't works yet. Then I checked the LVC244 and found that it have a short between LVC244.19(2OE) and LVC244.10(GND), I checked this line LVC244.19 are in parallel with U9(marking code ZO4G) I suspect a internal damage in IC. Someone can help me to found ic part for U9. It probable a

    single buffer ic?
