Usbd0 Stops Responding, Seems to be while writing to cf card Options

[nevarrie]

I have been running pdaxrom 1.1.0beta1 on my SL-6000L for a late few days. When I am at work I plug my Z into its dock and ssh into it and export the display by to my cygwin-x desktop. As long as I am only running programs I can stay connected for hours. But every once and a while I loose my ssh connection. After about the 10th times of loosing my connection I started noticing that is seems to be when I am writing to the cf card. Usually downloading something from the internet or installing a new package.

This maybe a hardware issue, but I can not remember every experincing this problem with OZ/GPE or with the sharp-rom.

Has anyone else seem this issue?

Have you tried writing to sd, for example? switching cf cards? It does sound suspicious, though. Are you using a browser on the z displayed in cygwin? or are you moving files scp from the desktop? or wget....? On beta3 fire has had some downloading troubles. I simply started using mozilla instead, if that is any help at all

I still have intermittent networking problems with my SL6000 (still RC12 though). As you say, downloading large amounts seems to set it off, and it hangs all networking - have to physically disconnect and reconnect. Haven't figured out what causes it yet...

I have been using the 2.6 kernel with OZ/GPE and have found I am seeing the same problem there also. I am going to start running some tests to see if I can get some more infomation to see if it is a hardware issue or a driver issue.

I've also seen this problem, both on the SL-5500 and the SL-860. I suspect it's a problem with the Windows USB driver trying to go beyond the limits of what the Zaurus can handle, as I've only seen the problem for transfer speeds of 500 kB/s or more.
Whenever the problem occurs, instead of physically removing the USB cable, I issue the following command:

CODE

/etc/usbcontrol net

which resets the USB connection, and sadly Windows sees as a disconnection and then a new connection.
And that's another thing, how the !@#* can I stop the Windows USB disconnection window popping up whever I disconnect the Zaurus? There's probably a registry hack to do it but I don't have permissions to change this at work.

Sounds like exactly the same problem, but I don't use Windows (Linux to Linux). Transfer speed is an interesting point though - the speed most likely stays consistently higher when transferring significant amounts.

I find that pulling the cable and plugging in again is just quicker/easier than resetting at the terminal, but your USB disconnection window sounds like a royal pain - I've never seen one of these, normally just the silly balloons when connecting (not disconnecting).

With respect to the actual problem, it seems most likely that it is a flaw in the USB network driver - can anyone running beta4 (2.6 kernel) comment on whether they have this issue? Hopefully it is fixed in future versions...
