Yes, I've been able to burn a bootloader on the Arduino UNO (R2) with a USBasp ISP device. Perhaps one of the lines necessary for ICSP has gotten fried.
Have you removed all shields and other hardware connected to the UNO?
Maybe the PIN 1 marker on the ICSP header is in the wrong place and you had the connector on backward?
Maybe reset pin fried on the 16U2 and is preventing programming. Its the only thing in common between the 2 device re: ICSP programming.

On the bad board, start checking the 16U2 - does the loopback test work?
