After looking around I had been able to localise the cause for the
described messages, see below:

When turning off hald no more of these messages appear. hald is trying
to poll the card reader, but it does not like this. So prohibiting the
polling in /usr/local/share/hal/fdi/preprobe/20thirdparty/ solves my
problem:
#cat 10-broken-usb-card-reader.fdi
<?xml version="1.0" encoding="UTF-8"?>
<deviceinfo version="0.2">
<device>
<!-- Generic STORAGE DEVICE 9744 -->
<match key="storage.bus" string="usb">
<!-- usb card reader Silverstone SST-FP35B doesn't like polling -->
<match key="@storage.originating_device:usb.vendor_id" int="0x05e3">
<match key="@storage.originating_device:usb.product_id"
int="0x0716">
<merge key="storage.media_check_enabled"
type="bool">false</merge>
</match>
</match>
</match>
</device>
</deviceinfo>
sg1 and sg2 are devices from my front panel card reader Silverstone
SST-FP35B:
#camcontrol devlist
[..snip..]
<Generic STORAGE DEVICE 9744> at scbus6 target 0 lun 0 (sg1,pass3,da0)
<Generic STORAGE DEVICE 9744> at scbus6 target 0 lun 1 (sg2,pass4,da1)
Is it possible that the last changes in usb code (xhci) or in cam code
are responsible for this? Does anyone else observe this behaviour?
A more generic approach would be to integrate the polling info into
/usr/local/share/hal/fdi/preprobe/10osvendor/20-broken-usb-sticks.fdi.
Is anyone willing to integrate the code (.fdi file or some quirks) in
the usb stuff?
In that case Linux is offering some more info about this device:
#lssub

Note, that the card reader from Benesys Logic is only one device of some
more (firewire, eSATA, USB slots ...), which are provided from the
'Silverstone SST-FP35B' front panel access unit.
Please let me know if you need more info or if I can test something.
Thanks in advance,
Rainer Hurling
