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

Before trying anything else, please update to current code and re-run
your tests.

Best regards,
