iPod Nano - Slow USB Speed

[bio]

Hi,
a sucesfully install rocxbox (rockbox-ipodnano-20060828.zip)
when i want to copy music with rockbox firmware the speed was about 100kb/s on computer with USB v.1.
On computer with USB 2.0 only 500 kb/s.

is any patch for this?
Did i something wrong?

thank

Tomas

Because RockBox does not have its own USB mode, it utililises the Ipod's diskmode. The diskmode is by default way slower than the Apple firmware, reasons to as to why this happens - ask Apple.

So in order to transfer at an ideal speed, it is recommended to boot into the default Apple firmware when transferring.

thank for reply.

disk mode on nanos isn't just slow; it's bjorked. [fyi] speaking from experience though, the disk mode on ipod videos isn't nearly as broken.

There is certainly a reason to as why diskmode functions at such a crappy speed. Apple can't be making 5 generations of Ipod without knowing of such a flaw.

Apple's diskmode is a maintenance-mode feature  -  transferring files when running the regular apple firmware is much faster.   Perhaps, Apple decided to reduce the speed of transfer in diskmode to make it more robust in some way?  (I wouldn't say it's a flaw)

I don't know if it is *entirely* Apple's fault.  On my nano in disk mode on a Windows 2000 machine I get high transfer speeds (USB2.0, etc), but for some reason on Windows XP machines I get slower transfer speeds (~USB1.0).  This happens consistently.

Are there plans to implement a rockbox USB transfer mode or will users always have to use the original firmware for faster file transfers?

[mightybrick]

Yes, from what I understand, Rockbox will eventually have its own USB transfer mode.
