He did say the COR #2 has a pullup resistor connected.
According to the wiring below you have the controller ptt connected to the ctcss input on the URI.
You have the ctcss input set to ‘no’ so the URI will not see the ptt from the controller.
I dont know what he pinouts on the controller are with out looking at the docs but do the following:
Connect the URI ptt to the controller cor input.
Connect the URI cor input (pin 8) to the controllers PTT output.
Connect the URI TX audio out to the controller RX audio input.
Connect the URI RX audio input to the controller TX audio output.
Make sure the controller port access is configured for carrier squelch (COR) active low only and not CTCSS and COR.
Set the node usbradio to use carrierfrom=usbinvert.
Restart the node.

I “think” the problem you are having has a simple fix.
I don’t know the specifics on the DMK URI
but a PTT normally switches to ground when active does not mean that it is high
when inactive. It can “FLOAT”. 0v and no ground when inactive.
The COR on the CAT1000 will be looking for a voltage when “INACTIVE” if you have
‘active low’ switch enabled. And without it, it will time-out.
You need to pull the PTT/COR line high with a 5v voltage and let the PTT pull it
low for active signal.
If you look at the CAT schematics, there is a test post for audio that you can hook
a small amplified speaker to and listen to the events on the cat1000 for better
testing.

I am having some problems getting PTT action on a repeater I am converting from
IRLP to Allstar.
The DMK-URI is interfaced to the secondary port of a CAT-1000 controller. And the
controllers second port is configured as active low. There is a 10k pull-up
resistor on the CAT controller’s COR#2 line.
URI DMK-URI CAT-1000 CAT-1000
Pin 1 PTT Pin 5 COR #2
Pin 7 CTCSS DET Pin 9 PTT #2
Pin 8 COR DET
Pin 20 GND Pin 17 GND
Pin 21 MIC IN AC Pin 23 TX AUDIO #2
Pin 22 LEFT OUT Pin 12 Rx AUDIO #2
And I am using these settings:
eeprom=0
hdwtype=0
rxboost=0
carrierfrom=usbinvert
ctcssfrom=no
txmixa=voice
txmixb=no
invertptt=0
duplex=1
plfilter=no
deemphasis=no
preemphasis=no
rxaudiodelay=0
Running asterisk -r shows that its supposed to be playing the time
(etc), but it never keys.
Suggestions welcome.
Thanks
