setreport returns a device not responding error

[yogish]

Hi,

I am able to open the device.
But when i try to set report using setreport.
ioretrunvalue = (*hiddeviceinterface)->setreport(hiddeviceinterface,
kIOHIDReportTypeOutput,0,OutputReport,
8,1000,nil,nil,nil);

It returns a device not responding error(kIOReturnNotResponding)
error.

How to fix this problem?

Thanks,
yogish

Try to Reset your Pram to see if that helps.

Plus what OS X version are you running and on what Mac?
