This link http://linmodems.org/ is a good starting point.

model number:
USB V.90 56K Fax/Modem
FCC Reg MQ4USM560

made in Taiwan, sold by Microspot in Switzerland

it is not obvious what kind it is, it simply makes no reaction, what ever settings in Linux I try.

Yes the linmodems site I looked at before, but all there seems to be so complex, supposing me to build new kernels etc. Have not succeeded with my internal modem , this is why i did buy the external one.

How do you know from outside what kind of modem it is?
