I have an AxisPad game controller from WalMart. The USB driver
identifies it as "USB HID v1.00 Gamepad [ANKO Corp. Gemini Industries
Inc. ]". The game pad doesn't work in any kernel after 2.6.0-test5.
Here is the error message:
Dec 26 15:23:24 Dawnya kernel: hub 1-0:1.0: new USB device on port 2,
assigned address 5
Dec 26 15:23:24 Dawnya kernel: drivers/usb/core/config.c: unexpected
descriptor type 0x1
Dec 26 15:23:24 Dawnya kernel: usb 1-2: can't read configurations, error
-22
I determined that the problem is a result of the config.c patch 5 of 9
that appeared in 2.6.0-test6. I commented out some parts of the code to
allow my game pad to work. I'm not saying what I did is correct, but it
works for me. Below is a patch for the 2.6.0 kernel that shows my
changes. Could anyone tell me a better way of fixing the problem?
Thanks,
Ashley
