Hi All - Firstly, apologies if this is the wrong forum for this type of problem, (maybe linux-usb?) if this is the case please let me know. I've got an Ubuntu 12.04 install and updated the kernel to 3.6.3 (I did this after looking at http://lii-enac.fr/en/architecture/linux-input/multitouch-devices.html and assuming support for my touchscreen monitor would be better the newer the kernel): Linux parsnip 3.6.3-030603-generic #201210211349 SMP Sun Oct 21 17:57:45 UTC 2012 i686 i686 i386 GNU/Linux and an HP Compaq L2206tm touchscreen monitor that gets detected like this: Oct 26 15:28:12 parsnip kernel: [ 98.500012] usb 1-2: new high-speed USB device number 5 using ehci_hcd Oct 26 15:28:12 parsnip kernel: [ 98.632382] usb 1-2: New USB device found, idVendor=0424, idProduct=2514 Oct 26 15:28:12 parsnip kernel: [ 98.632386] usb 1-2: New USB device strings: Mfr=0, Product=0, SerialNumber=0 Oct 26 15:28:12 parsnip kernel: [ 98.632542] hub 1-2:1.0: USB hub found Oct 26 15:28:12 parsnip kernel: [ 98.632625] hub 1-2:1.0: 4 ports detected Oct 26 15:28:12 parsnip kernel: [ 98.904119] usb 1-2.1: new full-speed USB device number 6 using ehci_hcd Oct 26 15:28:12 parsnip kernel: [ 98.997072] usb 1-2.1: New USB device found, idVendor=25aa, idProduct=8883 Oct 26 15:28:12 parsnip kernel: [ 98.997075] usb 1-2.1: New USB device strings: Mfr=1, Product=2, SerialNumber=4 Oct 26 15:28:12 parsnip kernel: [ 98.997078] usb 1-2.1: Product: OpticalTouchScreen Oct 26 15:28:12 parsnip kernel: [ 98.997080] usb 1-2.1: Manufacturer: TPV Oct 26 15:28:12 parsnip kernel: [ 98.997083] usb 1-2.1: SerialNumber: 0000 Oct 26 15:28:22 parsnip kernel: [ 109.000075] hid-multitouch 0003:25AA:8883.0004: usb_submit_urb(ctrl) failed: -1 Oct 26 15:28:22 parsnip kernel: [ 109.000082] hid-multitouch 0003:25AA:8883.0004: timeout initializing reports Oct 26 15:28:22 parsnip kernel: [ 109.000183] input: TPV OpticalTouchScreen as /devices/pci0000:00/0000:00:1d.7/usb1/1-2/1-2.1/1-2.1:1.0/input/input8 Oct 26 15:28:22 parsnip kernel: [ 109.000282] hid-multitouch 0003:25AA:8883.0004: input,hiddev0,hidraw2: USB HID v1.10 Mouse [TPV OpticalTouchScreen] on usb-0000:00:1d.7-2.1/input0 X happily detects the device as well: [ 5987.987] (II) config/udev: Adding input device TPV OpticalTouchScreen (/dev/input/mouse1) [ 5987.987] (II) No input driver specified, ignoring this device.

(interrupt to exit) I'm assuming the error in syslog ("usb_submit_urb(ctrl) failed: -1") might be at least part of the issue, but I'm not sure how to troubleshoot this further. Any hints or pointers would be greatly appreciated. Thanks!
