Hi All,

I'm looking to disable this device as I think it's possibly stopping my trackpad working...

Yoga 700 11.6in Intel m3-6Y30 - Sierra

The device:

-o Touchscreen@14410000 <class AppleUSBDevice, id 0x1000002da, registered, matched, active, busy 0 (1 ms), retain 14>

| | | {

| | | "sessionID" = 2321708663

| | | "iManufacturer" = 4

| | | "bNumConfigurations" = 1

| | | "idProduct" = 8274

| | | "bcdDevice" = 4115

| | | "Bus Power Available" = 250

| | | "USB Address" = 5

| | | "bMaxPacketSize0" = 8

| | | "iProduct" = 14

| | | "iSerialNumber" = 0

| | | "bDeviceClass" = 0

| | | "Built-In" = Yes

| | | "locationID" = 339804160

| | | "bDeviceSubClass" = 0

| | | "bcdUSB" = 513

| | | "USB Product Name" = "Touchscreen"

| | | "PortNum" = 1

| | | "non-removable" = "yes"

| | | "IOCFPlugInTypes" = {"9dc7b780-9ec0-11d4-a54f-000a27052861"="IOUSBFamily.kext/Contents/PlugIns/IOUSBLib.bundle"}

| | | "bDeviceProtocol" = 0

| | | "IOUserClientClass" = "IOUSBDeviceUserClientV2"

| | | "IOPowerManagement" = {"DevicePowerState"=0,"CurrentPowerState"=3,"CapabilityFlags"=65536,"MaxPowerState"=4,"DriverPowerState"=3}

| | | "kUSBCurrentConfiguration" = 1

| | | "Device Speed" = 1

| | | "USB Vendor Name" = "ELAN"

| | | "idVendor" = 1267

| | | "IOGeneralInterest" = "IOCommand is not serializable"

| | | "IOClassNameOverride" = "IOUSBDevice"

| | | }

Is there a nice way to do so?

Cheers :)

Disable the USB port attached to the device.
See guide:

Thank's RehabMan, That looks long! (And worth doing right if it's the solution I need) Is there a quick hack I can try to get it disabled quickly to see if it is the culprit?

Suggest you follow the guide to configure your USB correctly.
 
Yep, cool. However given further thought - It's unlikely that a USB touchscreen (which incidentally, works perfectly) is stopping my Trackpad from functioning. Keyboard works after using your Voodoo driver, sadly, no trackpad.

Any other ideas?

Your profile is not filled out as per FAQ, so no idea what hardware you have (you should fix, as per FAQ).
But it is possible your trackpad is I2C.
The FAQ provides a link for I2C.
 
Thank you RehabMan,
