Well, the only potentially relevant test I could find in the uhci hcd is that it returns -EINVAL if the USB device is low speed. But yours is high speed!

So can you please do the following: make sure that usbcore is loaded with usbfs_snoop=1 (usbfs_snoop is a module parameter). You can do this by (as root) removing usbcore then reloading it: rmmod usbcore modprobe usbcore usbfs_snoop=1 In new kernel I compiled usbcore into kernel, not as a modules. so IFAIK to load usbcore with parameter, I should append to kernel commandline usbfs_snoop=1 right ?? No, it should (I think) be: usbcore.usbfs_snoop=1 There's a general mechanism in the kernel whereby parameter p for module m can be specified on the kernel command line as m.p Ciao, Duncan.
