In kernel 3.13.0 I still have the same issues. So I also did some
debugging. Major findings:
- in hid-core.c the function usbhid_parse() is called after the joystick is
attached
- usbhid_parse() calls function hid_set_idle(), and this one fails while
sending an URB (details see below). Reason: the joystick returns -EPIPE.
- Same thing can be seen, if Wireshark is used to look at the traffic
- According to the documentation, EPIPE means "Endpoint stalled". It
furthermore says: "For non-control endpoints, reset this status with
usb_clear_halt()."
Unfortunately the return value is not checked in the kernel module. I
added this check, and tried to do a "usb_clear_halt". However, I cannot
quiet understand how things work in the code, and all my trials ended in
crashing the kernel.

submits URB and waits for response with a timeout
not: ret = usb_submit_urb() -> ret is zero
*actual_length = 1
ctx: struct api_context { .done:struct completion,
.status:int }
completion: struct { done: uint, wait:
wait_queue_head_t }
expire = msec_to_jiffies(5000) = 1250
not: ret = ctx.status or -ETIMEDOUT, since dev_dbg does not
appear
ret = ctx.status -> so the -32 is ctx.status. This is
"broken pipe", as seen in the Wireshark trace

Title:
Joystick (SideWinder FF2) Force Feedback doesn't reset properly
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
I've been trying to get the FF to work on my SideWinder Force Feedback
2 joystick without success so far.
This is what I get when I try to test it:
[code]
~$ sudo fftest /dev/input/event4
Force feedback test program.
HOLD FIRMLY YOUR WHEEL OR JOYSTICK TO PREVENT DAMAGES
Device /dev/input/event4 opened
Axes query:
Effects: Constant Periodic Spring Friction
Number of simultaneous effects: 0
Upload effects[0]: Function not implemented
Upload effects[1]: Function not implemented
Upload effects[2]: Function not implemented
Upload effects[3]: Function not implemented
Upload effects[4]: Function not implemented
Upload effects[5]: Function not implemented
Enter effect number, -1 to exit
[/code]
When I try any of the effects it does not do anything.
When I plug it in the USB port it shows this in the 'dmesg' output:
[code]
[ 170.280024] usb 4-2: new full-speed USB device number 2 using uhci_hcd
[ 170.489878] input: Microsoft SideWinder Force Feedback 2 Joystick as

Joystick [Microsoft SideWinder Force Feedback 2 Joystick] on
usb-0000:00:1a.1-2/input0
[/code]
This tells me that the kernel modules are present and being executed. It's
using the 'hid-pidff' driver and I found that the message about '0 simultaneous
effects' is generated here:
file: drivers/hid/usbhid/hid-pidff.c
line: 1178, function pidff_reset
From the code I can see it should at least find 2 simultaneous
effects, but it finds none and after 20 retries it fails and
continues.
After this, I leave my comfort zone, but I am happy to debug (with
some assistance) and try anything out. Maybe you'll be able to convert
me from being a Windows developer to a Linux developer :)
Cheers
