Hello all,
I want to be able to distinguish between two (or more) mostly identical USB
serial devices. The devices in question are UMTS modems. AFAIK they are
identical except for the SIM card and the point of attachment. Externally the
cards are CardBus devices with an integrated USB host adapter. The actual UMTS
device is (internally) connected to the USB host adapter.
If I have to cardbus sockets, how do I get from what I know ("the card is in
socket 0") to "I have to talk to ttyUSB2 to talk to the card"? I suspect I have
to follow the thread from /sys/bus/pci to /sys/bus/usb/devices, but how exactly?
Thanks in advance and kind regards
Joerg
