Regardless of your computer's components such as RAM and CPU clock speed, a bad USB controller or shoddy USB drivers can mean some quirky behaviour. I for one have not experienced all of these USB problems you guys are... perhaps you should make sure you have the latest chipset drivers and USB controller drivers. Philips is probably piggybacking the USB system on an antiquated serial based system, but that is not to say that it does not work well... it just does not work quickly.

I don't think Philips is to blame for the USB quirkyness. As a last resort, I might try re-flashing my firmware to make sure it is a good clean burn, but other than that, the low occurance of USB problems is probably pointing in a direction other than bad implementation by Philips.
