Sure. But not in the kernel. The kernel doesn't know that anything is wrong; all it knows is that the UPS isn't responding. As far as the kernel knows, maybe the UPS wasn't _supposed_ to respond. The responsibility for recovering lies with the program that's communicating with the UPS. According to your log, that would be blazer_usb. You should ask the people who maintain that program to add a workaround. Resetting the device would probably work.
