PCMCIA to triple USB card

is this device recognized?
may you post the output of lspci, lsusb and lsmod with all of the devices connected?

Hi Ernia
lsusb is not present in my installation:
#find / -depth -name lsusb* command gives a "not found" message.
I can't say nothing about lspci and lsmod until I'll go home.

root@sl3:/home/fabio# tazpkg search-pkgname lsusb

Search result for file : lsusb
================================================================================
usbutils
zsh

================================================================================
2 pkg(s) found with file : lsusb

so you need to

 tazpkg get-install usbutils

to have the lsusb command installed

See if pcmciautils is installed:

tazpkg search pcmciautils

If not:

tazpkg get-install pcmciautils

Pcmciautils was just installed while usbutils has been installed with tazpkg.
Now my USB storage is correctly detected and mounted.
USB internet key is correctly detected: this is shown by lsusb command.
Now I would connect to the internet, but how?

Install these:

tazpkg  get-install wvdial

tazpkg  get-install linux-dialup

Try Automatic Installation first:

just a little note: the fact that you see your USB internet key does not prove that it is correctly detected (correct module loaded) but just that the kernel sees the device.
if Mojo's suggestion does not work (it should work) check if you have a /dev/ttyACM0 or /dev/ttyUSB0 file.
first time i connected with my nokia n78 as a modem i needed to manually

modprobe cdc_acm

and then put cdc_acm in /etc/rcS.onf in the LOAD_MODULES row to have it automatically loaded at startup.
