** Summary changed: - Network Manager .8 broken with UM175 (Verizon/Alltel wireless) + Modem Manager setting bad baud rate, breaking pppd connections.

Additional information from logs is below. And I've rebooted to Fedora 11 between failures with Karmic to verify that the modem and local provider are functional. -------------------------------------------------- Aug 16 20:18:18 karmic kernel: [ 94.086140] cdc_acm 4-1:1.0: ttyACM0: USB ACM device Aug 16 20:18:18 karmic kernel: [ 94.088315] usbcore: registered new interface driver cdc_acm Aug 16 20:18:18 karmic kernel: [ 94.088340] cdc_acm: v0.26:USB Abstract Control Model driver for USB modems and ISDN adapters Aug 16 20:18:23 karmic kernel: [ 99.060269] scsi 6:0:0:0: CD-ROM UM175AL CD-ROM 2.31 PQ: 0 ANSI: 2 Aug 16 20:18:40 karmic pppd[3897]: Plugin /usr/lib/pppd/2.4.4/nm-pppd-plugin.so loaded.
