Hi all,

sorry for posting here, but i wasn't sure where to ask.

I got a O2 UMTS Stick and was trying to connect via ppp.
Entering the PIN works, the LED changes from green to blue but when i start pppd it dies right after some IPCP requests with the error "Modem hangup".

UMTSMON sais it's a E161, however it's original vendor/product-id  was 0x12d1:0x1446. I used usb_modeswicht which switches the id's to 12d1:1001.
I got 3 ttyUSB devices and usbmon also displays valid data.

Some hinds how to fix pppd would be very cool.

Thanks a lot!
