Dear Debashish Rath,
In message 24A35C16137FE049838D189639DD567F0846F87C@eu-exh-02.EU.TRID.COM you wrote:
I found the issue. In usb_stor_get_info function of common/usb_storage.c I add the following: (dev->descriptor.idVendor =3D=3D 0x0204 && dev->descriptor.idProduct =3D=3D 0x6025)
to skip the ss->transport_reset(ss);. This I took out from the linux kernel= code.
Now its working for me.
Congratulations. Can you now please submit this change as a proper patch so others can benefit from it, too?
