Re: [Linux-usb-users] 2.6 PCMCIA/USB question

[Joerg Pommnitz]

I had hoped that one can figure things out from /proc and /sys. SHould'n
there be a way to do this? And no, trial and error is not really an
option. The devices in question are WCDMA/UMTS mobile data cards. They
will differ only by the SIM card inserted by the user. The ICCID of the
SIM is unknown during development and I would like to avoid to many
configuration files.
