以前のエントリで紹介したが
eeePC
と
e-mobile
のアダプタ（D02HW）
を使用しているが、
PCの電源を入れる前からUSBアダプタを
差していれば問題なく
gnome-ppp
から利用できるが、
PCの電源を入れてからUSBアダプタを
差しても
/dev/ttyUSB0
にデバイスが現れないため
モデムとして利用できない
状態になっている事に気づいた。
以前の
UNR9.10
のころは
このあたりも問題なく
動いていたので
UNR10.04LTSにアップグレード
したのが原因のようだ。
以下、アダプタを差した状態で
ブートしたときの状態。
dmesg
内の関連メッセージを抜粋。
CDーROM
と
モデムとして
認識されていることがわかる。

---------------------------------------------------
要は、ブート後にアダプタを差し直した際に
この状態を際限できれば良いということになる。
おそらく
udev
まわりの設定を見直すことになるだろう。
今日は時間がなくなったのでここまで。
