    Default upa usb 1.3 green clone problem

    Hello!
    Recently bought an upa-usb v1.3 green clone and i'm having a problem with it. Port 8 doesn't switch states (low, high, z-state) except only when i remove the usb/external power jumper, then all the ports switch through low/high/z-state, checked that with a DMM and it's correct
    changed: 74hc, mcp, reflashed firmware, all the zenner diodes, fuse is ok and so on
    what could possibly be the problem?
