Re: [Xen-devel] anyone using pvusb?

Hi James,

I have tested with current tip.
My flash drive worked properly.

I found no regression with my environment.

The main difference between us is flash drive.
In your environment, do other devices become
the same error? Or, some devices work?


My test environment is as follows.

PC:             Core 2 Quad Q9450 with Q35+ICH9DO
Xen:            xen-3.4-testing.hg (c/s 19749)
Dom0 OS:        CentOS 5.3
Dom0 kernel:    linux-2.6.18-xen.hg (c/s 931)
DomU OS:        CentOS 5.3
Dom0 kernel:    linux-2.6.18-xen.hg (c/s 931)
Tested Device:  Buffalo RUF2-R2GS
                (VendorID:0411, ProductID:0098)
