uhci is not processed horizontal queue

I am back on programming operation system and I am still working on UHCI. Now I am confused what happens in QEMU. I trying to read device configuration descriptor. SETUP packet is send right. IN packets are transferred right. But when SPD occurs, execution is not moved on horizontal in queue to OUT package but transfer next IN packet with 0 transferred bytes and execution ends. Here is Bochs dump(I think it is more useful than my code):

You are not setting bit 29 in the Status DWORD (DWORD1). To enable Short Packet Detect, bit 29 must be set.

Thank you! Somehow I did not know this. Now my driver works well in QEMU so I decided to try it on my test computer. I do it and something strange happen. Reset and enabling port works well, SETUP and OUT packages are send well, but IN packages have set active bit and have set CRC timeout bit. Please why is it?
