"eject", not "safely remove".

I'd like it to work with "safely remove" as well, but I need to find out more at what exactly Windows does then

Thanks for the clarification - I've tested under Windows and it works.

NOTE:
With an SD card inserted, both drives need to be ejected before the USB icon is removed.

EDIT: Rasher did say Eject - my error!

I've tested under Windows and Linux and BeOS and Haiku

My e250 is working with usb on Windows and Linux.

BeOS with the Haiku usb stack can detect it but fails to mount with an error 0x0000000085 iirc I can't seem to reproduce it since now it won't even detect it just locks up (The BeOS USB stack that is) probably a problem on the Haiku end

OK, after further testing, there seems to be something strange going on with my 5.5g iPod.  I'm using today's build, where 'eject' drops you straight back to the OS.  It seems like whenever I do so, even if I've barely changed anything at all, my drive churns and churns for a long time.   Like an hour or more.   And seriously depletes the battery.  And a couple times, when I've rebooted the player, it's restarted wanting to commit the database.

I think it may be attempting to entirely rebuild the database whenever I eject it.  Either way, there's no reason for the drive to churn for more than a couple minutes unless I do some kind of major file copy.

Also, it doesn't seem to be charging very well, if at all, when in the Rockbox OS.  Charging when in USB mode seems about right.

Any ideas?

Edit:  Scratch all that.  I regressed it back to basic 3.1 and I'm still having the same issue.  I think my database got hosed somehow.  I'll play around with it more tomorrow...

A question regarding USB and the e280. Will it work reliably on a Mac? I'd test this myself, but the e280 and Mac (Powerbook, I think, running OS 10.26, I think) are in Chicago, at my sister's, and I am in North Carolina. I bought the Sansa for her as a gift, but she's been unable to get the Sansa firmware to work reliably with the Mac, and of course (although Rockboxed) it's needed to be in the Sansa firmware for file transfers.

So will equipping her Sansa with USB-enabled Rockbox help her Mac to play nicely with the player at last?

Many thanks....

It depends entirely on why it's unreliable currently. UMS mode in the original firmware shouldn't be unreliable on a mac unless there's something about the hardware that's a problem or unless it's just the usual MacOS disliking FAT32 issue. Rockbox can fix neither of these. If it is some obscure OF issue on the other hand, Rockbox might well resolve it. Since you haven't really described the problem, nobody can make a remotely accurate guess.

Thanks a lot for this feature!
I have WinXP and iPod Video 80GB.

In the original ipod USB mode the transfer speed is about 9-10 MB/s.
In rockbox USB mode my files transfer about 1/3 slower with 6-7 MB/s.

I do not see the battery icon in the rockbox usb mode and do not know if it charges and when it is fully charged. Does it charge in USB or not?

strangely enough, I just rebuilt my Haiku OS install and it is working with my sansa e250 now. not sure what the deal was there. I might have to try packageing the updated USB stack for BeOS since it still seems broken

This is great news!  ;D I was wondering though - does the USB connection allow my Sansa e250 to access micro SD cards larger than 2Gb? I would try it myself, but I haven't got anthing bigger but I was thinking about getting a 4Gb one.

Anyone tried it? Does it work? I remember that the OF on e250 doesn't, but I'm not sure if that's hardware or software related.

Thanks everyone for your hard work making something so cool!

I have an e280 with an 8 gig micro card in it.  I'm able to access the micro card fine through Rockbox.  No need for original firmware now.

OK, it seems to work on my Ipod Video, but I have my concerns...

I never use rockbox to charge my battery. I have a higher level of confidence using the OF for this task. Now, how good is the battery charging algorithm in RB? Last thing I want is for my Ipod to be a guinea pig of some sort while the charging algorithm is being perfected. Has it been perfected????

Also, I find it very convenient for RB to resume playback automatically on boot up. If this feature can be implemented for the USB function, that would be great. In other words, the moment that the USB cable is pulled out, RB should know and automatically perform a task (which the user can specify) such as resume playback.

Thanks

George

Charging is a separate matter from the recent USB stack commit.  Charging should already work in the iPods as far as I know.

On 5G and 5.5G (Video) iPods, charging is controlled by the LTC4066 chip.  The charging part of that chip doesn't need to be configured by software.  Charging from FireWire works perfectly.  If the iPod doesn't charge from USB, that is due to the USB power section of that chip.

That's a good point regarding other iPods however.  Has it been confirmed that charging is hardware controlled on those?   The 1G Nano has an  LTC4066 and the 1G Mini has an LTC4055.  Those are probably used for charging, but it would be good to confirm.  What about 2G Mini and 4G/Colour/Photo iPods?

yeah, i run rockbox on sansa c250 and charging always worked. but now the question is how do you charge your player (say, sansa c250) without putting it into the stack mode?

also, i don't know if it's off topic, but as long as it was already mentioned, is there anyone here who's using >2gb microSD cards on sansa c250 with rockbox ? they say the early c250-s are compatible with rockbox and incompatible with >2gb. mine is one of the first ones sold in toronto, i really don't want to waste money, someone, please let me know if 4Gb & 8Gb SDs work with the current build?

Yes, I'm using an 8GB SDHC.
