Passwort fuer den Administrator abgefragt. Danach mittels make den Treiber uebersetzen und mit cp ./ch341.ko /lib/modules/$(uname -r)/kernel/drivers/usb/serial/ in das System kopieren. Starten Sie danach den Rechner neu, ein korrigierter Treiber fuer die CH340G USB2RS232 Bruecke ist somit verfuegbar. #
8000 count setting? I'm a "little" confused with those 10- 13 location values... Btw. I used a cheap CH341A programmer and test clips from eBay, programming worked just fine. Only needed to turn meter's mode switch to voltage position, didn't work in the off position. Hi, I will try to add some info. From
