I just found that using an older kernel in Fedora = Core 4 may =A1=B0solve=A1=B1 the problem.

When I tested Fedora Core 4 guest domain, the kernel version I used was 2.6.17-1.2142_FC4, and it cannot recognized the USB = disk.

I just changed the kernel in guest domain to version 2.6.11-1.1369_FC4. Then the guest domain can recognized the USB disk. I = am wondering why the USB support in QEMU depend on the guest domain kernel. = And I would like to know which kernel version can support QEMU USB = emulation.

BTW, I also found that Windows XP guest domain can = not recognize the USB disk, while Windows XP SP2 guest domain can recognize the USB = disk. So it seems like that the guest Linux/Windows domain should have some = =A1=B0special feature=A1=B1 to work with the QEMU USB emulation successfully. = Isn=A1=AFt it strange?

Subject: [Qemu-devel] USB = storage cannot be recognized on guest Linux domain?

I am using Xen 3.0.3 with QEMU-DM 0.8.2 on a Intel VT platform. After insert a USB storage, and use =A1=B0usb_add=A1=B1 = command in QEMU monitor, the storage should be recognized on guest OS. I tested this = with a Windows XP SP2 guest OS, it doing well.

But when I test the =A1=B0usb_add=A1=B1 command with = some Linux guest OS, it seems that the guest OS cannot recognize the USB storage. And the = device number and address in guest domain are always =A1=B00.0=A1=B1. The Linux = guest OS I tested including Fedora Core 4 and Fedora Core 5. Does any one also meet = this problem or have some idea on this? Feedbacks will be highly = appreciated.

Thanks
