+assert issue locates in hw/usb/dev-storage.c:248: usb_msd_send_status
+
+Hello,
+
+I found an assertion failure through hw/usb/dev-storage.c.
+
+This was found in latest version 5.1.0.
+
+--------
+
+qemu-system-x86_64: hw/usb/dev-storage.c:248: usb_msd_send_status: Assertion `s->csw.sig == cpu_to_le32(0x53425355)' failed.
+[1]    29544 abort      sudo  -enable-kvm -boot c -m 2G -drive format=qcow2,file=./ubuntu.img -nic
+
+To reproduce the assertion failure, please run the QEMU with following command line.
+
+
+$ qemu-system-x86_64 -enable-kvm -boot c -m 2G -drive format=qcow2,file=./ubuntu.img -nic user,model=rtl8139,hostfwd=tcp:0.0.0.0:5555-:22 -device piix4-usb-uhci,id=uhci -device usb-storage,drive=mydrive -drive id=mydrive,file=null-co://,size=2M,format=raw,if=none
+
+The poc is attached.
+
+
+
+poc doens't run on fedora:
+uhci: common.c:59: gva_to_gpa: Assertion `gfn != -1' failed.
+
+Can you build qemu with DEBUG_MSD enabled (see hw/usb/dev-storage.c),
+then attach both stderr log and stacktrace?
+
+thanks.
