this issue in case linux-input mailing list is dead (can't find recent

Hi all,

I am playing with a multi-touch capable touch screen from the
above mentioned vendor and are experiencing some problems here.
On a 3.1.0 derivative kernel it kind of works, looks like this:

On 3.3.0 it doesn't think it is an input device at all:

[   73.776660] usb 3-1: new full-speed USB device number 3 using xhci_hcd
[   73.817163] usb 3-1: New USB device found, idVendor=2453, idProduct=0100

[   73.817173] usb 3-1: SerialNumber: SDW190W2M5T

On 3.0 on the other hand it actually registered multiple HID devices, which
is what I think should happen with this device, because it's datasheet
says this:

"""
The mid-size family of touch screens, when enumerated on the OS, expose 5
top level USB HID collections. The following table describes these in
detail: following table describes these in detail:

Collection Description
----------------------
Win 7 Touch Collection

Generic Mouse Collection
Generic Pointer Collection
Baanto Touch (Custom HID) Collection

Report Data
-----------

Control Packets
N\A – Future Use
Single Touch Packet
Multi Touch Packets\Control Packets
"""

Any ideas who is at fault here?

Thanks,

Tvrtko

This is all I see with HID debugging turned on (3.3.0) after plugging in the device:

No input device of any kind registered after this point.

Hints about what is going wrong?
