I went through this same exercise over the weekend. In mine the cm108 chip appears dead as 5v is getting from the USB connector to the chip. Mine seemed to always run hot. it would go offline intermittently over the last year.. Usually power cycle the computer and it would fix it.. This time no.. It is one of 3 URI's on this computer. I had to replace it pending possible repair. Looking at it , I am not going to be able to replace the cm108 chip.

When I got there, the computer and radio were fine, but the URI's lights were all off. Tried plugging it into a backup computer, with no luck. The unit is only a couple months old. Is there anything I can try? 73 Bobby KF4GTA
