I am trying to get my motion LE1700 tablet to work with 10.5.2

Graphics works great. Sound works, but only through line out/in, and the digitizer works well - using tabletmagic.

A new network card is on the way, to replace my 3945.

 

The main remaining problem is the keyboard!

If I plug a USB keyboard in, it works great (that's what I'm typing on now). But the keybaord of the tablet itself does not work. The tablet is a "slate", so you can attach and detach the keyboard. The keyboard has a single special plug that it attaches with, and includes a track point (mouse), keyboard, a USB port at the back, and it also supplies power to the tablet.

 

When I plug it in, Hardware growler reports a IOUSBHubDevice, and then a "Semtech PixKey". The USB plug that is attached to the keyboard seems to work. The trackpoint and the keyboard don't work.

 

BTW: The keyboard does work in linux, so I could potatially spy on it there..

 

Does anyone have any idea how to get it to work? Do I need to add the Vendor/device ID to any kext, or some such?

As far as I know, this is a USB keyboard. But, maybe it somehow is a PS/2 keyboard and mouse? Could it be that these are the PS/2 problems that others where reporting? How could I tell?

 

And I also have a simpler question: hardware growler does report when the keyboard is plugged and unplugged. But I can not see the event on any log file. I would really like to know more about what is going on, what errors occur when I plug the keyboard in... Is there any log file I could look at?

 

Thank you very much for listening!

I have the same hardware (LE1700) and issue with the detachable keyboard... would like to know if you get it working!

 

Along these lines, was wondering if there is a way to place the PNP info for this keyboard in a plist file so it sees and treats it like a typical USB keyboard? Just an idea, haven't attempted this, not sure if it would be worth trying.

 

Thanks

Still no answer, but I'm slowly understanding some more.

 

Both in the Linux and in the OSX report, the Semtech device is reported as having three interfaces.

ioreg -l reports

IOUSBInterface@0

IOUSBInterface@1

IOUSBInterface@2

 

And, so does linux. In linux we can see that interface 0 connects to the keyboard, 1 to the mouse, and 2 I'm not sure.

When I looked at my Dell keyboard, it also reports a IOUSBInterface@0, which is then connected to IOUSBHIDDriver.

For now, I think that is the problem. IOUSBInterface@0 should connect to IOUSBHIDDriver also on the LE1700, but for some reason doesn't.

When I look at the IOUSBHIDDriver report for the Dell keyboard, I can see that it seems the driver claimed the interface, because

bInterfaceClass + bInterfaceSubClass + bInterfaceProtocol matched what the interface specified.

when I look into IOUSBFamily.kext/Contents/PlugIns/IOUSBHIDDriver.kext/Contents/Info.plist, I can see the following:

						<key>CFBundleIdentifier</key>
					<string>com.apple.iokit.IOUSBHIDDriver</string>
					<key>HIDDefaultBehavior</key>
					<string></string>
					<key>IOClass</key>
					<string>IOUSBHIDDriver</string>
					<key>IOProviderClass</key>
					<string>IOUSBInterface</string>
					<key>bInterfaceClass</key>
					<integer>3</integer>
					<key>bInterfaceProtocol</key>
					<integer>1</integer>
					<key>bInterfaceSubClass</key>
					<integer>1</integer>

As far as I understand, you need bInterfaceClass=3, bInterfaceProtocol=1, bInterfaceSubClass=1.

According to http://developer.apple.com/qa/qa2001/qa1076.html, that then gives you a "score" of 60000. This is indeed the score reported for the Dell keyboard. On the LE1700, IOUSBInterface@0 reports exectly the same numbers:

	| |   |   | +-o IOUSBInterface@0  <class IOUSBInterface, registered, matched, active, busy 0, retain 5>
| |   |   | |   {
| |   |   | |	 "bInterfaceProtocol" = 1
| |   |   | |	 "locationID" = 18446744073665576960
| |   |   | |	 "bcdDevice" = 100
| |   |   | |	 "bConfigurationValue" = 1
| |   |   | |	 "iInterface" = 0
| |   |   | |	 "idProduct" = 8549
| |   |   | |	 "IOCFPlugInTypes" = {"2d9786c6-9ef3-11d4-ad51-000a27052861"="IOUSBFamily.kext/Contents/PlugIns/IOUSBLib.bundle"}
| |   |   | |	 "bInterfaceSubClass" = 1
| |   |   | |	 "bAlternateSetting" = 0
| |   |   | |	 "IOUserClientClass" = "IOUSBInterfaceUserClientV2"
| |   |   | |	 "bInterfaceClass" = 3
| |   |   | |	 "bInterfaceNumber" = 0
| |   |   | |	 "bNumEndpoints" = 1
| |   |   | |	 "idVendor" = 1146
| |   |   | |   }

(which also fits with what Linux reports), but for some reason this is not claimed by IOUSBHIDDriver or any other driver. I'm not sure exactly why. Could it be that this is because it is just one of 3 interfaces on the same device?

Maybe I should try to match one of the other possibilities mentioned, like (idVendor + bDeviceSubClass + bDeviceProtocol), or maybe

(idVendor + idProduct + bInterfaceNumber + bConfigurationValue)....

 

Does anyone understand these things? :jester:

I modified /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/IOUSBHIDDriver.kext/Contents/Info.plist, and added the following:

	   <key>Motion Keyboard</key>
	<dict>
			<key>CFBundleIdentifier</key>
							<string>com.apple.iokit.IOUSBHIDDriver</string>
							<key>HIDDefaultBehavior</key>
							<string></string>
							<key>IOClass</key>
							<string>IOUSBHIDDriver</string>
							<key>IOProviderClass</key>
							<string>IOUSBInterface</string>
			<key>bInterfaceNumber</key>
			<integer>0</integer>
			<key>bConfigurationValue</key>
			<integer>1</integer>
			<key>idProduct</key>
			<integer>8549</integer>
			<key>idVendor</key>
			<integer>1146</integer>
	</dict>

But still no go.... nothing changed.

Finally got it working after reading, search doesn't work very well.

Ghost got it from one of your other posts.

 

Try copying the whole Apple16X50Serial.kext to the desktop, delete the one in the extensions, reboot, then put it back in, repair permissions, and reboot again.

 

The only thing I have left is the outer buttons and the fingerprint reader. Have you guys found anything for that.

My USB mouse stops working about ever 10 minutes so I just unplug and plug back in and it works.
