Hello, linux-usb-devel.
I use 2.6.10 kernel and pppd-2.4.3 on Fedora Core 3 distr.
I configure my pppd to connect to internet via 3Com 56k Business Modem (USB).
Everything is fine.
But when i want disconnect from internet i do: 'killall pppd'.
Dialup connection broken and i use my telephone line to speak.
When i want to connect again i try 'pppd call cnt' and nothing happened.
/var/log/messages write: chat "script failed".
Even minicom cannot work whith modem.
Ufter rebooting everything is ok.
I tryed pppd-2.4.1 ... all too most.
If after connection kernel internaly block /dev/ttyACM0 wich doesn't unblock
after disconnect?
2.6.9 (default FC3 distro kernel) + pppd-2.4.3 worked fine, with out rebooting.
2.4.22 kernel + pppd-2.4.1 worked fine, with out rebooting. What's the problem ?
Some info (2.6.10 kernel):
