USB 2.0 problems (I/O errors with ehci driver)

Hi,

I bought a USB 2.0 PCI card (manufacturer Hama, chip
ALi M5273).

The card works fine using Windows XP.

Using Linux, however, I have severe problems. I can
only use the card with the slow usb-ohci module, otherwise
I get I/O errors.

Here is what happens:

1. I use the hotplug services; my system is a Suse 9.0
   with current patches; i.e. I use kernel 2.4.21-144-athlon
   which is configured for good performance on athlon systems
   (I have an ECS board K7S5A with Athlon 1800+).

2. when I plug in an USB 2.0 memory stick I see the following
   in /var/log/messages:

   Jan 3 21:11:25 baileys kernel: hub.c: new USB device 00:0f.3-6,
assigned address 2
   Jan 3 21:11:25 baileys kernel: usb.c: USB device 2 (vend/prod
0x5dc/0x200) is not claimed by any active driver.

   Jan 3 21:11:28 baileys kernel: sda: Write Protect is off
   Jan 3 21:11:28 baileys kernel: sda: sda1

3. when I mount the device and do some copying the following happens:

   cmds:
> mount /media/sda1/
> time cp -rup /media/sda1/* .
   [...]
   cp: reading `/media/sda1/filed.jpg': Input/output error
   cp: reading `/media/sda1/filee.jpg': Input/output error
   cp: reading `/media/sda1/filef.jpg': Input/output error
   [...]

   /var/log/messages:
   [...]
   Jan 3 21:29:18 baileys kernel: SCSI disk error : host 1 channel 0

   Jan 3 21:29:18 baileys kernel: I/O error: dev 08:01, sector
140719
   [...]

   Some files are copied correctly. The errors do not start
immediately. The
   amount of data copied varies. On the memory stick are about 105
MByte of
   data. Sometimes the errors start almost immediately, on other times
the
   errors occur after 95% of all the data is already copied.

4. The errors do not occur if I unload the ehci_hcd and then try
again. The
   errors also do not occur if I use Windows XP

My conclusion is that this has something to do with the linux USB2.0
implementation or configuration. My guesses: IRQ settings, ehci
driver,
usb kernel configuration. But what can I do? (Further information is
attached
below, i.e. output from dmesg, infos from BIOS, kernel configuration,
loaded
modules, output from usbview, /proc/bus/usb/devices).

Remarks:

- I tried with ACPI switched on and off (-> same problems)
- I enabled/disabled the slow on-board USB (-> same problems)

I'd be very grateful for every hint. I simply don't know how to
proceed.

Thanks,

Jan
