Attached please find some more information. It seems to me if I unplug and plug in PICkit 2 back slowly, it would be okay. If I unplug and plug back a bit faster, then it starts to show problems. Is this normal among HID device? Could it be that there is a possible firmware bug? In fact there is a low speed PICkit 1 device (similar to PICkit 2 but it is a low speed USB 1.1 device) which never show this problem. PICkit 2 is a full speed USB 2.0 device. Regards, Xiaofan The following are the output of dmesg of three times unplug and plug. 1) First plug in : no problem [EMAIL PROTECTED]:~$ dmesg ...
