I bought a IIyama T2250MTS touchscreen (introduced in 2010) with a
Quanta Optical screen in it that is attached through USB. It fails to
register as a hiddev at kernel level with the following message:
[17302.085109] usb 1-7: new full-speed USB device number 13 using xhci_hcd
[17302.226874] usb 1-7: New USB device found, idVendor=0408, idProduct=3000
[17302.226879] usb 1-7: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[17302.226884] usb 1-7: Product: Optical Touch Screen

[17327.881661] usbhid: probe of 1-7:1.0 failed with error -110
udevadm monitor shows this message upon plugging in the device:
KERNEL[17301.926216] add /devices/pci0000:00/0000:00:14.0/usb1/1-7 (usb)
KERNEL[17301.926841] add

UDEV [17327.620847] add
/devices/pci0000:00/0000:00:14.0/usb1/1-7/1-7:1.0 (usb)
Looking into kernel.log shows the same message. Device is seen as usb,
some sort of attempt is made to connect to it, and this fails.
xinput --list does not see it:
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ PixArt USB Optical Mouse id=9 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Power Button id=7 [slave keyboard (3)]
↳ Sleep Button id=8 [slave keyboard (3)]
↳ UVC Camera (046d:0821) id=10 [slave keyboard (3)]
↳ DELL Dell USB Entry Keyboard id=11 [slave keyboard (3)]
O yes and the device properly works on Windows 10... I've exchanged
the USB cable for another one. No solution.
Installing the Ubuntu upstream kernel 4.16rc4 did not solve the issue.
All additional info is available in the Ubuntu bug report:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1753497
I'm not a regular kernel debugger but I have compiled my own kernel in
the past and applied patches (was an experienced Gentoo linux user),
so I am willing to test patches or do other things needed to get this
fixed.
Thanks for your attention.
