#19585 new defect

gcom freezes on a Netgear DGN3500

Description

I configured a 3g-wan connection on a Netgear DGN3500 but it's not working.
pppd is not launched because gcom freezes. Likewise it freezes if I run it from the command line.
If I remove the file gcom/comgt the connection is established successfully.

I'm not very familiar with Trac, and I can't find a way to relate tickets. But #18424 is related.

Also, editing gcom calls out of 3g.sh, I get to the pppd call, but it never establishes a connection either. So it seems it's not just gcom, but anything communicating with a USB modem. I've tried 3 different USB sticks, all of which on my laptop.
