usbasp usbasp_transmit: Broken pipe

[Michael (c0d3z3r0)]

Hallo!

Ich habe folgendes Problem:
Seit heute funktioniert mein usbasp nicht mehr. Sobald ich versuche per 
avrdude meinen atmega zu schreiben (auch wenn gar kein AVR dranhängt) 
kommt folgende Fehlermeldung. Gestern Abend hat alles noch wunderbar 
funktioniert -.-

make program
avrdude -p atmega168p -P usb -c usbasp -B 2  -v -v -y -U flash:w:main_rx.hex -U eeprom:w:main_rx.eep

Bis ich ihn ab- und wieder anstecke, dann geht's von vorne los...

Hatte jemand schonmal das gleiche Problem und vielleicht eine Lösung?

Danke!

Unter Windows das gleiche Problem, wie man in den Screenshots sieht... 
:(
Beim ersten Versuch wird der usbasp erkannt, beim zweiten dann nicht 
mehr...
