I've run into a weird one, and if anyone has any ideas, I'd appreciate it.
I'm working with a joystick from CH Products. It works OK when it's connected
to the system at boot, but not correctly after a hot connect, or a driver
re-load. The data reported never changes. In fact, the values seemed to be
latched to whatever the joystick would report when it's first connected. For
example, if the joystick button is held down when the USB connector is plugged
it, the button state is reported ON ever after, regardless of the actual button
state.
I've tried this on a number of systems, with both VIA and Intel UHCI
controllers - it's all the same. I've tried the uchi driver instead of
the usb-uchi driver; still no good.
If I run Win2000 on the same box, it works each time without fail.
I've turned on debug in the driver, and the interrupt transactions are
occurring, but the data in the transfer buffer is the same each time. I even
zero-ed out the buffer after each report was received, to make sure the data
was changing. I've dumped the TD records, and there's no error status or NAK
reports.
I've used SnoppyPro to find out what setup messages are being sent to the
device, and don't see anything particularly different from what the usb-uhci
driver generates.
I'm working with
kernel 2.4.21-0.26mdk
usb-uchi.c Revision: 1.275
hid-core.c: v1.8.1
CH PRODUCTS CH HFX 2 AXIS 1 BUTTON JOYSTICK 68e e2 0
There don't seem to be significant differences between the UHCI driver in the
linux-usb.org BitKeeper 2.4 archive and the one I have.
For what it's worth, here are some extracts from the log files.
Thanks in advance for any help with this.
