As far as I know, QEMU does not have any of its own special USB handling. It has USB emulation. But this does not influence how it handles disk images... even if they are on a USB device. Perhaps you can demonstrate some QEMU command-lines to indicate how you are testing these disks? Regards, Shaddy
[Qemu-devel] QEMU only support USB endpoint 02(output) and 81(input)?
Hi guys, I found that some USB disks do not work in QEMU. I collected seven types of USB disks, and tested them in QEMU. Four of them can work properly, but other three do not work. I compared their information in /proc/bus/usb/devices, and found that the four good disks all use endpoint 02 as output endpoint, and use endpoint 81 as input endpoint, while other three are not. So, is QEMU only support USB endpoint 02(output) and 81(input)? I put the USB information of the seven disks below. The first four disks can work with QEMU, and the last three disks do not work with QEMU.

RE: [Qemu-devel] QEMU only support USB endpoint 02(output)and 81(input)?
I used QEMU 0.9.0 to do the testing. All the seven USB disks can work properly in host OS (Linux 2.6), so the USB devices and its interaction with the kernel drivers should be okay. So the problem must be in QEMU USB code.
