usb_linux_update_endp_table: No such file or directory

[Xavier Gnata]

Hi,

I'm trying to plug an Ipod on a winXP guest.
The host is a 2.6.27 and I'm using kvm-77.

I get this (as root to avoid stupid +w problems):

husb: open device 7.7
husb: config #1 need -1
husb: 1 interfaces claimed for configuration 1
husb: grabbed usb device 7.7
usb_linux_update_endp_table: No such file or directory
Warning: could not add USB device host:05ac:1262

kvm is supposed to work with every usb device, isn' it?
This one is nothing else but a usb_mass_storage device so I cannot see 
where the problem is.

A lot of newer iPods and iPhones require usb2 which qemu/KVM does not  
emulate. You also want to make sure nothing in the host is claiming it  
before the guest does.

USB2/ehci is still not supported (certainly not in something as old as 
kvm-84). There was some work going on recently to support it, but I don't know 
how far they have made it.
