The CuPhone USB to RJ11 adaptor is based off the same TigerJet TJ560B chip as the Digium S100U device. It is a single port FXS interface. I would like to be able to use this device as a timing source instead of ztdummy on an Apple XServe G5 system running Yellow Dog Linux.
I was able to get the wcusb module to load by changing the product ID from 831c to c31c. The vendor code is still the same.
