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:
[5523460.737596] usb 1-1.6.1.2: new full speed USB device number 18 using ehci_hcd
[5523460.824952] usb 1-1.6.1.2: New USB device found, idVendor=2453, idProduct=0100
[5523460.824959] usb 1-1.6.1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[5523460.824964] usb 1-1.6.1.2: Product: SDW-190W2-M5T-XXX-XX-PRD
[5523460.824968] usb 1-1.6.1.2: Manufacturer: Baanto
[5523460.824971] usb 1-1.6.1.2: SerialNumber: SDW190W2M5T
[5523460.833233] input: Baanto SDW-190W2-M5T-XXX-XX-PRD as
/devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.6/1-1.6.1/1-1.6.1.2/1-1.6.1.2:1.0/input/input159
[5523460.833926] generic-usb 0003:2453:0100.00A3: input,hiddev0,hidraw3: USB HID v1.10 Mouse [Baanto SDW-190W2-M5T-
XXX-XX-PRD ] on usb-0000:00:1a.0-1.6.1.2/input0
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
[ 73.817167] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 73.817169] usb 3-1: Product: SDW-190W2-M5T-XXX-XX-PRD
[ 73.817171] usb 3-1: Manufacturer: Baanto
[ 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:

"""
Any ideas who is at fault here?
Thanks,
