hmmm... the pppd on the empeg will not run on the usb-device:

pppd /dev/usb 115200 nocrtscts local noauth defaultroute passive
===> no pppd process

pppd /dev/ttyS1 115200 nocrtscts local noauth defaultroute passive

and

pppd /dev/ttyS2 115200 nocrtscts local noauth defaultroute passive

works....

any suggestions ?
