Perhaps you should set this to find out what's going on both when you have success and failure, to see if there's a difference. > # Optional increase of "delay_use" for the usb-storage driver; there are hints > # that a recent kernel default change to 1 sec. may lead to problems, particu- > # larly with USB 3.0 ports.

IIRC (15 years) wvdial uses ppp. I know that ppp can be made to log debug information. I can't remember whether wvdial does. (I never used it but I helped occasionally.) So once again you need to look at the logs when it works and when it doesn't. Cheers, David.
