Configure USR5610 modem?

I’ve recently come into possession of this modem which is supposed to be supported in linux kernels but I’m not sure how to set it up or detect where it is located (dev/ttxx)

any advice?

Without installing or loading any specific driver for this modem, can you post the output of:

ll /dev/ttyS*

This modem is quite old and in earlier SUSE versions it was getting configured as /dev/ttyS14

linux-641g:/home/jason # ll /dev/ttyS*
crw-rw---- 1 root dialout 4, 64 2010-02-06 04:52 /dev/ttyS0
crw-rw---- 1 root dialout 4, 65 2010-02-06 04:52 /dev/ttyS1
crw-rw---- 1 root dialout 4, 66 2010-02-06 04:52 /dev/ttyS2
crw-rw---- 1 root dialout 4, 67 2010-02-06 04:52 /dev/ttyS3
crw-rw---- 1 root dialout 4, 68 2010-02-06 04:52 /dev/ttyS4
crw-rw---- 1 root dialout 4, 69 2010-02-06 04:52 /dev/ttyS5
crw-rw---- 1 root dialout 4, 70 2010-02-06 04:52 /dev/ttyS6
crw-rw---- 1 root dialout 4, 71 2010-02-06 04:52 /dev/ttyS7

Nope, it is not there.

The file is dated very old. I doubt it works. Anyway, see if it works.

should I try an earlier version of suse?

You can try installing it on the latest openSUSE version. Anyway, since it is a RPM file, you can always uninstall.
