@blankmac Ugh, that's a bummer.
Seems like Linux aren't doing anything special there, looks similar to your code.
Noticed you're not checking for BTNLESS here https://github.com/blankmac/AlpsT4USB/blob/410e2daac0aa56d0504f333ae710e9194b833e74/AlpsT4USB/AlpsT4USB.cpp#L137
BTW his IOReg shows he does have another I2C HID device :P
Just for the sake of testing we can add
kIOHIDVendorIDKey and see if the error message has changed
Can be done in Info.plist rather than code too
Am I looking at the wrong IOReg? :/
I'll get his device ID added properly and it will probably attach but I doubt it will work.
Although the other guy had a U1 based device so who knows, maybe it will.
Not sure if it's the one you're referring to tho
Hi all. I mentioned in the main chat that I'd like to get the Cypress running on my C720. I feel honored to be added to this chat but I'll mention that as tech savvy of an end-user as I am, I have close to 0 coding skills. As Ben suggested I plan to use the Elan satellite as an example, and somehow port the device from 1.0.4 of voodooi2c. The plan makes sense in my mind, but I don't want to bother anyone to walk me through things - perhaps if you can suggest some online learnings I could check out to put me in a position to do this effectively, I would appreciate it. On the other hand, if anyone does have time to do it, I am available to test.
Read the IOKit reference as a start, make sure you're familiar with C/C++
Then read the old Cyapa code, make sure you understand it
Then read the VoodooI2CELAN code and understand how a satellite works (Might want to read device nub code either?)
You might want to look at the old ELAN code for reference...
Finally, port the code. Looking at the ELAN diff should give you a better idea on how it should work.
granted, my touch pad is USB tho.
@isi95010 Don't be discouraged or overwhelmed. I started at ground zero myself in the code department with the VoodooI2C project a few years ago.
Hey guys, seems the old methods of live logging to the console from the kernel don't work anymore (ie - IOLog). I'm trying to chase down this problem and would like to output some of the input data live -- blankmac/AlpsT4USB#7
Any advice?
you generally will want to use the boot-arg
msgbuf=1548576 as well to increase the max size of the dmesg buffer. That's the best way I've found, though I would like iolog to work again ;-;
oops, msgbuf should be
1048576, not the number I gave before
Hiya. So I have a unique scenario in which my laptop has a PS/2 keyboard but an I2C touchpad. I cannot get them both working consistently due to conflicts between the kexts -- when the touchpad works, the keyboard is disabled until a wake/sleep cycle. Is there a way to properly use both VoodooI2C and VoodooPS2?
it's dependency hell
