Nice to hear you,
try to answer on your questions:
1. sometimes I get the error message when I switch on the board without
connected USB-Device. When I connect an USB-Stick I get all messages which
shown successful communication between platform and stick.
2. I have two different sort of USB-Sticks to test. Both behave different
during connection but later I can mount then successfully.
First Stick:
hub 1-0:1.0: connect-debounce failed, port 1 disabled
hub 1-0:1.0: connect-debounce failed, port 1 disabled

Then my next hands on:
/var # mkdir usbstick
/var # mount -tvfat /dev/sda1 /var/usbstick/
/var # cd usbstick/
/var/usbstick # ls

mm scripts sound usr
I am still using LINUX 2.6.12 with your patches for isp116x and changed
isp116x_start() to register usb_root_hub.
Found:
usb-isp116x-hcd-01.patch
usb-isp116x-hcd-02.patch
... 06
at kernel.org. I will check them tomorrow.
With PTD_TRACE and URB_TRACE I can get huge report of td: and <- from and to
the Stick. Within there are blocks with partition tables which are
definitely correct. But depending on the Stick I see more than one cycles of
attemption to collect all information for the SCSI-Subsystem (look above).
Are there any race-condition between USB and SCSI-Subsystem. Untouched
original sticks work best, formatted sticks with XP or LINUX produce
difficulties up to that they are going offline after unsuccessful reset.
Mouse are running OK except that my target has no interface to use it - I
only get the vendor and serial no. nothing else happen. I think interrupt
and bulk transfers running if the first control transfers are successful.
Delaying command transfers seem to be also interesting for me.

Can you please enable CONFIG_USB_DEBUG and repost the
output.
Do you see this error message only when using a specific
flash drive? Or also for different flash drives? Or also for
other types of USB devices like mice, keyboards?
Which version of the kernel are you currently using?
Recently I posted a number of isp patches for 2.6.13-rcX on
USB list. Are you using any of these patches?
Olav
