[App_rpt-users] USB Adapter has no EEPROM installed

Is there anything that the URI will do with this EEPROM tuning info that Asterisk cannot do?

to put the EEPROM in the connector with the cable physically connected to the radio,
so that you can change URI's, and the tuning parameters move with the radio, not the URI.

Yes, there are people that want the EEPROM in the URI, but I really am not sure why.

you can order a uri with the memory installed.

 Does the DMK URI ship with a EEPROM installed?
 I think it's external on the DB25 male connected to the URI. If there.

  Two questions for the group: 
  #1 I'm seeing this in my /var/log/asterisk - I'm using a DMK URI with EEPROM and a Motorola GM300 with one of Marshall's Motorola Maxtrac, GM300 and M120 16 Pin Radio to URI cables. 
  [Nov  1 11:30:05] NOTICE[6852] chan_usbradio.c: USB Adapter has no EEPROM installed or Checksum BAD on channel usb42372

  I understand that the benefit of the DMK URI with EEPROM is that the interface configuration can be stored in the URI as apposed to (where else?) - is this URI EEPROM feature taken advantage of with app_rpt and associated drivers? 
  #2 How do I choose which channel driver to use - simpleusb or USBRadio?  From what I've been able to learn through varius wikis and posts on the subject, I would want to use simpleusb because all of the hardware connections for COS and CTCSS are provided so there is no reason to use the DSP features of USBRadio thus simplifying what the driver has to do and perhaps lowering the CPU utilization.  I've also read some posts that describe audio degredation in the USBRadio driver but I can't tell you the cause.  I expect the right answer here is for me to try out both and experiment - which I will do but would appreciate any wisdome from the group on their experience with these drivers when using the DMK URI and hardware connections for COS/CTCSS.  My current configuration below is getting favorable audio reports. 
  I have no simpleusb.conf in my /etc/asterisk I have usbradio.conf and usbradio_tune_usb42372.conf 
  I have the following in my rpt.conf: rxchannel=Radio/usb42372 
  I have the following in my usbradio.conf: 
   [usb42372]
