I just found that using an older kernel in Fedora Core 4 may “solve” 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 “special feature” to work with the QEMU USB emulation successfully. Isn’t 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 “usb_add” 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 “usb_add” 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 “0.0”. 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
Xiaoyang
