I found on vinted (europe) a modem that might work, might... is a usr805637. I said might because it looks ( and might be) exactly the same as the usr5637 , and that one apparently works. Either way is at a very good price and it cames with a another device that eventually can be sold.

It's only about 10 euros, the postage it will depend on which country you live.

For those living in europe, I found a compatible USB Zoom modem ( 3095 ) for 20€ ( he might accept a lower offer, who knows ? ) This time is on wallapop
