Ipod Nano Second Generation USB mode

[ViDER]

Hello to any one reading this topic !

This has been asked around the forum, but I'll still get back to it, as at this point it is just annoying.

I have (as the title indicates) an Ipod Nano second generation, about two weeks ago my Nano would no longer show me the "Do NOT disconnect" status screen whenever plugged to a computer (I have two desktops at home). The devices battery indicator would show the little lightning symbol, but not the "Do not disconnect" screen, also, despite the fact that the device indicates that charging is in progress (the lightning symbol at the top) upon disconnecting the cable from the PC (safely ejecting the device from the OS) it would NOT charge at ALL.

I brought the device to school too see if the issue at hand is related to the device or to my desktops USB hubs, the same story occurred at school as well. I tried charging my device by using a colleges USB cable, surprisingly a connection was establish between the device and the school PC.

On the same day, I got home and tried connecting the device to my main workstation (using my USB cable), after playing around (disconnecting and reconnecting devices from my USB hubs) for a while, I manged to find a port that worked (the "Do not disconnect" screen showing up).

As soon as the Nano got recognized, I installed Rockbox (NOTE: At that moment the device was connected at USB 2.0 and was working fast, as Rockbox installation was a snap).

Once Rockbox was set on the Nano, I decided to boot the device into Disk Mode. Unfortunately, now the Nano would only transfer files at a speed of maximum, 980 Kilobytes / Sec (USB 1.1 transfer rate).

I tried everything (or maybe I have missed something?), restarting the device and getting into disk mode right away (Select + Play), restaring the device and getting into Apples disk mode (Restarting the device and setting the HOLD switch to ON, then plugging the USB cable to the device), tried running Rockbox then connecting the cable while in Rockbox (no success).

I went as far as to restore the device and copy the songs (from iTunes) onto the device (an awfully painful process) then install iLoader. This time around once iLoader was installed Rockbox would no longer start, neither setting iLoader as the default loader didn't do any good (The problem was still there).

I uninstalled iLoader, restored the ipod and set back Rockbox.

What's the cause to the low transfer rate? The cable? the device? the OS?

If you have a suggestion, please feel free to add it.

First things first,

This is a Rockbox forum, and, although iLoader can boot a Rockbox'ed device (namely Nano2G) this is not the place to find support for iLoader directly.

Secondly,

You didn't mention what version of Rockbox you have installed.
If it is the release version 3.6, then, you won't see the "USB Screen" from rockbox. It will drop to the OF "Disk Mode" when there is a USB connection.

If you're using one of the daily builds, then you'll see (or, should do...rather) the Rockbox "USB Screen".


It rather sounds like you're using an *OLD* build that still has USB HID enabled for the Nano2G (removed due to problems enumerating on some OSes), but this is speculation...as I'm not aware what build you're using.

Try updating your build to the current daily build (despite the "Unstable" tag it has, it is really quite stable indeed...) and see if it magically fixes your issue.
You never know

As for the transfer speed issue, as far as I know (although, it has been debated) the OF has slightly faster transfer speeds than Rockbox on the Nano2G...but it is certainly nowhere near USB 1.1 speeds.


EDIT: I reread this, as I was sure I had missed something...and found that you even had problems getting the device to connect to your PC even after resetting it to a default state using iTunes.
Advice would be:

1: Try another USB port
2: Try another cable
3: Try another OS (You didn't mention what OS you were using)
4: Try another PC

As you already have done number 2 and 4 (simultaneously) and it worked, it seems to suggest that the problem lies in one of those areas.
