## AI overview

A GSoC Week 6 progress report on ReactOS USB stack work describes fixes to Plug and Play handling in usbhub and libusb. Driver Verifier issues were resolved for usbhub, while OHCI testing remained incomplete and further refactoring was planned.

## Source excerpt

This week I have continued fixes in PnP handling of our USB stack. I was focused on usbhub and done number of fixes there. Let me describe process from begining. Issue on MS's hidusb removal. As you may remember from previous post, now MS's usbccgp works under 2k3, sitting on the top of our ohci-hub pair. But that time I have also faced issue on it's removal. So to simplify debugging I have reproduced same issue with hidusb and saw the same behaviour under 2k3.
