New USB Stack

[zajacattack]

OK, I would like to know:

(1) How is the new USB stack work going? What has been accomplished? What needs to be accomplished? What are the problems?

(2) Is there any way I could help? If so, how?

(1) How is the new USB stack work going? What has been accomplished? What needs to be accomplished? What are the problems?

We have charging working (i.e. the device will request 500mA of current now, not just make do with the default 100mA).

We need to make mass storage work properly. Currently Zagor is having trouble making this work with blocks larger than 64kb (if I recall correctly).

(2) Is there any way I could help? If so, how?

Yes - work on making the mass storage allow larger transfers. Please join IRC for more details

I have noticed that the new USB stack causes problems with the Sansa crashing the OS when plugging in USB.  

It happens about 50 percent of the time, in which the screen starts to fade to white and lockup.

Is there anything I am doing wrong, or has anyone else experienced this issue with the Sansa E series.

I have noticed an entry in flyspray, but I would like to know if this is a known issue?  

Thanks to all for all their work.  I am so appreciative of all your efforts and hard work.

Which targets use the new USB stack (iPods and Sansa)?
I assume the Gigabeat already had USB support built in?

[GodEater]

Currently it's all the portalplayer 502x targets :

iPod 4G, iPod Color/Photo, iPod 5/5.5G, Mini 2G, and Nano 1G
iRiver H10
Sansa e/c 200

I got this once. I don't know if it is still there, I plugged the sansa in two times since then without it happening.

Hello I have Rockbox r15804-071125 on iPod 5.5g.  Vista is the PC OS.

The new USB stack is welcome and have a couple comments/questions.

1. The iPod now seems to charge without booting into iPod mode.

2. I'm having difficulty getting Vista to recognize the iPod.  I cancel out of the expected "new driver" screen but the iPod drive doesn't appear.  After booting into several modes and inserting the USB cable I finally get it recognized.  It almost appears that I get the iPod recognized by accident.  Once finally recognized file deletes and transfers seem OK.  I've looked at the manual.  Any thoughts about the iPod beng consistently recognized by the OS?

Thanks!

TexasRockbox, I think this might be due to Vista.  There are a couple of threads of people on Vista having similar problems.  I've had no problems connecting my iPod 5.5G to Linux and Windows XP machines.

EDIT: After googling, it looks like Vista has a few USB Mass Storage problems in general.

I cancel out of the expected "new driver" screen

What? Why?

EDIT:  Nevermind me everybody, I just got lost in all my tabs and forgot what topic this was.  Thought we were talking about the OF USB connectivity.

On the front page it says:
"2007-11-23   New USB stack with limited capability. Currently it only requests full charging power. Ignore driver popups from Windows."
So doesn't that mean we hit cancel at the new hardware wizard?

I'm having the same exact issues as Texas, but I don't use Vista.

Computer recognizes rockbox, but it doesn't show up as a storage device.
Mysteriously starts working after about 4,5 boots.  It does the usual "do not disconnect." thing at that point.

Thanks in advance for your time and RockBox rules

because the usb-storage protocol is currently not working, there is a bug with the controller, which is currently investigated and the whole usb-storage code isn't fully implemented yet.

so be patient, it will work sooner or later

So just to clarify :

1) By "Ignore driver popups in windows" we do indeed mean click "Cancel". Once the USB stack is working properly you won't see these popups at all, since no driver will be required (other than the USB Mass storage one already present in windows).

2) In order to have your ipod show up as a drive in windows currently, that means you have to have it either in emergency disk mode, or in the original firmware. There are countless threads elsewhere detailing how to enter both those states on the ipod, so I won't repeat them here.

1. The iPod now seems to charge without booting into iPod mode.

And for crystal clarity :

This is the currently-working part of the new USB stack functionality (and a very welcome one for us Sansa users!)

I would just like to report that charging works great with my iPod 4G Color in Vista. I do get the popup message but I hit cancel. If you guys need testers for this I would like to volunteer but currently my Vista pc has died. If this is still going when I get a new power supply I can definitely volunteer my 4G.

Charging works beautifully on my iPod video. I hooked it to my Linux box at home and my PC here at work (Windows XP SP2). Both PCs detect it and allow charging to start.

Soon comes the day when we can say "au revoir" to the Apple firmware!

One weird thing. My main computer died so now I am using my spare Windows 2000 Professional machine. When I plug the iPod in while rockbox is running, the "found new device: rockbox player" comes up on my computer but rockbox shows the usb plug image and restarts the iPod in disk mode meanwhile my computer is trying to install the software still. I just find it weird that rockbox restarts the iPod on Windows 2000 and not Vista, unless something changed in the build in the last week that caused this.
