Dear Mr. Wolfgang, I found the issue. In usb_stor_get_info function of common/usb_storage.c I add the following: (dev->descriptor.idVendor == 0x0204 && dev->descriptor.idProduct == 0x6025)
to skip the ss->transport_reset(ss);. This I took out from the linux kernel code.
Now its working for me.
Regards Debashish

I was trying to add usb support to u-boot for my Arm cortex-A9 processor ba= sed board. I am using "U-Boot 2009.08".
Before trying anything else, please update to current code and re-run your tests.
Best regards,
