joydev bug with playstation USB adapter

Quoted 8 lines

Hi, I have two playstation USB adpters, one of them with this [1] "lsusb -v" (the other I don't have access to ATM) and they both give me the following buggy behaviour: the range of the sticks is limited
- i.e. value 32767 is reached when the stick is only about half-way through its run, leaving a big dead zone after that. This happens on all axes and recalibrating with "jscal -c" didn't help.

I'm on an up-to-date Archlinux, kernel 3.7.5, and have tried various kernel versions down to 3.0.1 with same results.

Is there any other info I can provide?

[ adding Anssi to CC ]

Hi renato,

there is a driver for this particular device (hid-pl), written by Anssi Hannula.

So before I'll be digging into this any further -- Anssi, does this limited range sound familiar to you when it comes to 0x0810/0x001 device?

Thanks.
