Poor Philips. I have a 2.8 ghz PC with 1GB RAM. I plug in a USB scanner, Sony USB digital camera, Sony PDA. They do not lock up; they do not act flaky. Plugging them in via USB is not an adventure. It always WORKS.

Enter the Philips TSU-3000 and TSU-7000. They do work "most of the time" but can lock up 3-4 times in a row; reboots, etc., seem to matter little, more the luck of the draw. PENG and PPENG "exit" at the darndest times all on their own.

Even with less than optimal PC's, the USB implementation shouldn't be that hard to nail down - it seems to work quite well for other devices; except, of course, for the NG Philips remotes...
