Hi = Nenad,

 

Both kernels are configured to = support USB devices. The config files are put in the = attachment.

 

USB storages can be recognized by = both kernels successfully if I install the systems directly on hardware, = instead of install the systems as guest domains in Xen/VT environment. =

Hi = Xiaoyang,=

 

did you check whether = both kernels are configured to support USB?

# cat = /proc/config

or
