[Asterisk-Users] ztdummy problems

[Iain Stevenson]

The ztdummy driver relies on an active USB bus that uses Intel's UHCI 
standard.  It basically patches itself into the interrupt chain for the 
uhci driver to get the regular interrupts needed to drive the pseudo TDM 
bus within asterisk.

Your computer may use the ohci standard for USB in which case ztdummy can't 
be used.  Your best bet then is to buy and install another USB card that 
conforms to the uhci specification.  You may need to build the uhci kernel 
driver for this.
