I use my USB all the time.
There is two main differences between USB 1.1 and USB 2.0: Data rates and power consumption.
- Thumb drives are backward compatible with USB 1.1 in terms of data rates ( they will be slower on USB 1.1 but will still work), most thumb drives doesn't need power levels of USB 2.0.
- Ipods will still charge using USB 1.1 it will just take longer, apple link hereDV-400v doesn't support USB 2.0 data rates:
Here is a detailed discussion for the USB cababilities of the DV-400 here
bottom line is the transfere rates of the USB port on the DV-400 around 3 Mbps max as opposed to 480 Mbps for USB 2.0 (thats why any higher quality xvids regardless of the resolution will be choppy on the USB and play fine on the DVD)DV-400v doesn't support USB 2.0 power levels:
Check the manual, it clearly states (Chapter 6):
"If a USB ERR message lights in the display, it may mean that the power requirements of the USB device are too high
for this player."
Now given the fact that there is no internally powered USB device out there that requires power more than what USB 2.0 already provides, this is pioneer saying "don't count on compatibility with USB 2.0 devices."
I think I can safely conclude that the DV-400v USB port IS NOT USB 2.0 (even if some reports that the Mediatek Chipset used would support USB 2.0, experiments showed that Pioneer has messed it up with the implementation.
Sorry for the long post, I hope it was informative,
