up & down (y-axis) not working in 3.8

SeC

@Ravneson Hey, there are 2 locations to edit:
lib\modules\4.4.11+\kernel\drivers\hid
lib\modules\4.4.11-v7+\kernel\drivers\hid

file name is hid-dr.ko

MAke changes to both files, as I don't know which one will be loaded for you. Save changes then reboot, Y axis should be fine.

Look at the picture below, I've marked pattern you need to change (just swap 33 with 31, keep in mind those are hex values, not text). Picture is from windows box, so don't worry :)

Ravneson

@SeC Thank you!! :) :) That worked just brilliantly! (for anyone else having the same issue, hexcurse turned out to be a simple & fast hex-editor that can be installed & used on ones Pi)

Cheers!

@lohocla I fixed this my hexediting HID driver for my USB arcade controller - there's two bytes needed to change - look at my issue reported here https://github.com/raspberrypi/linux/issues/1527/ to see which bytes must be swaped.

Did you report this upstream btw as mentioned https://github.com/raspberrypi/linux/issues/1527/#issuecomment-225559930 ? (Would be good to get the fix in a future release).

@BuZz Didn't have time to prepare proper patch with description, but I have this in my TODO list this week.

Hi btw, hope you don't mind me popping in and getting some help, I seem to be having the same problem as you chaps ... now I'm a Linux noob (Boo) ok :/ I've done so well as to install hexcurse and also find the correct files to edit, I have edited these files but come across a write problem. 'Cannot write to file: bad permissions'

Help me please, as I'm going 1 step forwards and 2 steps back.

Thanks. Lee.

Ravneson

@Roadkilluk Are you running hexcurse as a superuser, i.e. "sudo hexcurse <filename>"? If not then that could explain why you don't have permission to write to the driver files.

Spot on, thanks for that "Super User DO" ... I see :)

Cheers, I'm now losing at Sensi Soccer with no excuses !!

Hey, did you find the time to make this happen?

Pyjamarama

A patch would be lovely!

I do not know how to install a hexeditor to retropie :(

Pyjamarama

Since I do not know how to install hex editor in PI...

If I take these files, copy them over to my PC using WinSCP, open them with XVI32, do the substitution then...Can I copy the files back to Pi using WinSCP or they are protected and cannot be overwritten?

Pyjamarama

@Pyjamarama I answer myself. Yes you can. You need to ho bash and sudo cp blah blah (winscp cannot overwite them)

After hex edit the driver, the left and right buttons does not work in ES(I use L/R button to skip page). But these button works in games. Does anyone has this problem?

Pyjamarama

re configure the controller in emulaionstation

jretropie

@Pyjamarama I did that but it's not working.

This seems like a big enough issue to warrant a patch. It seems that encoder that shows up as Dragonrise is used by many for its ease of use and price. If I FTP the file off, edit it in Windows, and FTP it back, will that be ok?

Fabpie

Hi everyone!

I had this issue too... I just have been able to fix the "y" axis by inverting the values from the "hid.dr.ko" but the "X"axis still don't work outside Emulationstation.
I'm so close to set up DAPHNE emulator but now the only axis it works is the "y".
I'm using a dragonrise usb generic controller.
Can I fix the "x" axis from "hid.dr.ko"? If yes can you please tell me how to do it.

Please help.

Thanks in advance

retropiepghguy

@Fabpie it's crazy that such a widely used device has such a huge bug. That encoder is sold all over the place. I hope to try the fix today.

Fabpie

@retropiepghguy Thanks in advance... If you do you'll be my hero! finger crossing ;)

retropiepghguy

@Fabpie from what I am reading, getting the hex editor installed is the tough part. I may ftp the file off, edit it on Windows, and ftp it back. Luckily I have a test system.

Fabpie

Thanks again!
Just a little question, do I have to give you my hid.dr.ko file?
