[Qemu-devel] [PATCH 2/3] usb: change VID/PID for usb-hub and usb-msd to prevent conflict |
Date: |

From: Roy Tam <address@hidden>
Some USB drivers, for example USBASPI.SYS, will skip different type of
device which has same VID/PID. The following patch helps preventing
usb-msd being skipped by the driver.
