  • Hello

    I have a USB multilink and PROG12Z to program a MCU in win7 32bit OS, everything works normally, but if I restrat the PC,the USB multilink will be lost in system,I need to unplug and plug the USB cable,then the USB nultilink will restores in system.

    I changed PC, the problem also occures.

    please help me how to solve this problem.



  • Greetings,

    Which multilink do you have? If you have our latest USB Multilink Universal hardware, then you should not be seeing this problem. Only our older models like USB ML 12 or USB ML CF has this issue. There is no workaround because it is a problem with the USB driver chip used in the hardware.
