Indeed, that's exactly what's happening. >> What has been your solution to get the ZTE working? >I've blacklisted devices 0, 1 and 2 using the attached patch, taken >against 2.6.34-rc6.

No such thing as "blacklisting". >Without the patch, I'm able to use wvdial against ttyUSB3 to dial up, >but the device is unresponsive to anything apart from a PPP LCP >disconnect. For the olicard100 it's been port 2, dialling, pppd starting up, but lcp cfg req timeouts. At least with the olicard100 there's been no real dialup. Conn endpoint has never been talking to the device.. Thanks alot for your hint. Previously I intended to wait for the .34 to come out, but regarding the promising changes in option.c I will reconѕider this. What are your overall xp with .34 so far? rc-7 is out, quite a rc count.. Maybe the .34 is also levelling out these days.. :) Cheers, Nils
