Jiri,

Are you OK with this change?

Yann,

Is the device usable at all with generic HID driver? If it isn't then
maybe we should blacklist it unconditionally?

Thanks.

Hi,

Without the libusb based proprietary stack, the device is unusable under linux.

If i correctly understand, libusb need a driver to be present in the first place,
(even a useless generic-usb) to be able to grab the device. If we unconditionally
blacklist the device and the ebeam driver isn't loaded (not compiled for example), no way
for libusb (and the stack) to handle the device.

As stated before, i'm not comfortable with the risk of breaking other hypothetical support,
even proprietary.

Yes, please take it through your tree together with the proper driver and 
add

to the HID blacklist additions.

Thanks,
