Motorola XPR8300 repeater, no USB comms

 

Hi guys.? I have an issue with USB comms to an early model XPR8300 repeater.? ?It's has been extremely stubborn.? ?I've tried everything, different PC's, different cables, both CPS16, and CPS2,? tried the rear USB on the TX and RX bricks individually, tried as USB-2 hub, still NOTHING.? No USB comms on all 3 connections.? Just keep getting comm errors, no USB problems like this with my other trbo radios and the same programming gear.? ??
?
The thing that's DIFFERENT on this repeater vs. my others is ver. 1.04.01.???My others that are Ver. 1.06.20 have no problems with USB ports.? ?Obviously, I can't even upgrade the firmware if? I can't talk to it.? Anyone seen this?? Thanks so much in advance!
 

I ran into what I think is the same issue a couple years ago. I had picked up an XPR8300 that CPS absolutely could not see. I bought a replacement network interface thinking it was a hardware problem; it was not.

You need to find old CPS to be able to interact with it. Motorola apparently quietly drops support for old firmware in some releases. You can then upgrade it to something that newer CPS will see. IIRC, the older builds are on the MOL website too.

I think the unmentionable tool that rhymes with Crab was able to see it in all cases, which helped determine that the repeater was OK, just too old for modern CPS to see.

Hi Matt,
Also make sure the network cable is unplugged.?

Also to look at, is replacing the front display board (with the front panel LEDS) which affects both the USB and LAN connectivity. I've had to replace a number of these in the past on different XPR8300 repeaters. The USB interface controller resides on this board.

I've never seen Motorola provide a Field Service Bulletin on this issue, although I felt that they should have.

OK finally done pulling my hair out on this!? ?Tried old versions 15, 14, 13, dug out old Win 7 PC's, etc. still no comms, ready to throw this thing off the balcony, then FINALLY dug out a 8?year old CPS 11 disc out of my drawer and it worked!?? WTF Motorola!@#$!

THANKS MATT and the group!

Now if I could only stop the PA sections from blowing up on these old things. : )
