2.6.18 is a little old. Is it repeatable on later kernels? Ideally 2.6.22-rc5? Thanks. Dear developers, additional information from me an Martin Dauskart md001 <at> gmx.de: Martin tried: unload ehci-hcd module wait a moment load ehci-hcd by hand --> works I just tried: unplug 1.1 HUB plug 2.0 HUB plug card reader --> works But if you reboot then, the problem comes up again. I tried it with etch available kernels, latest kernel: Linux 2.6.21-1-686 #1 SMP from backorts.org on original etch System. So the next hint seems to be at the initialization procedure within cold plug. Hot Plugging seems to have no problem. Chears & have a nice day. Wolfgang PS: Keep Martin on CC. Excuse me, but it is in fact not working.

As Martin Dauskadt told me, he has the same problem with this kernel version(s).
The problem occurs exactly, when you want to write or read to or from an USB mass storage device. Not whe you just plug in the device. In my case you must have a card inserted to the card reader, mount it and read/write to it.
You are totally right, the HUB has to swith to right USB subersion. KDE controlcenter tells me, that on the ehci module is a HUB in version 2.0 is used, and the card reader is USB 1.0.

debug logfile usb.log with usb2.0 only devices and kernel 2.6.22.6
Dear kerneldevelopers,
please find the usb debug log file from my computer.
Test Case: Only usb 2.0 devices, 1 hub and 1 card reader (only ehci driver is used).
After 2 seconds the devices are disconnected from the hub, resetting the usb-storage devices.
I tried this without the hub, directly attaching the card reader to the hub. This behaves in the same manner.
Additionaly I tried to connect a usb stick to the hub, this shows the same behaviour either.
So my proposal is, that probably something is wrong in usb storage code.

kernel 2.6.22.6 complete debug log usb storage
Hi,
again a complete log from my computer with kernele 2.6.22.6 and usb-storage.
Further details:
It seems, that the problem only occurs, when a media is inserted in the card reader. I tried to copy a 10 MB file to a 32 MB CF Card. Copy to the card was succesfull, then I want to list and delete it for test purposes. List was successful, between list and typing delete .... the error occurs.
I copied the whole /var/log/debug to this file.
If it is usefull, I can add dmesg output too.

Should now be working in 2.6.30 kernel versions. If not, please bring it up on the linux-usb@vger.kernel.org mailing list. |
