It works fine. Check to make sure your printer is configured to use a valid port. It does not matter what port the cable is in at initial computer boot, the 740 will not print to that port, but will print to the either port once the cable is pulled out and reconnected to a port. P. S. I do not want to reinstall the Epson software as I have done it more than ten times so far, after following instructions from Epson on how to remove the software and clean up the registry before doing so. Each reinstallation adversely affects other components in my system and results in the same error message when I try to print from the Stylus 740.
Power management is most beneficial for laptops and is near useless for PCs.
The Epson Stylus Color 740 USB printer is printing as it should. Indeed the USB shares an IRQ with other devices. I've really got to get more sleep. Look in Hardware Resources, IRQs. I have the Epson Stylus 740 attached via USB to a PC operating Win 98.
