Hi,

I flashed the latest SPK XMOS firmware (1.5 ) and find that the LEDs brighten up as per direction of audio arrival.
However when I open the HID device and try to read input reports, ReadFile() is blocked for ever.

Wonder if USB interrupt as indicated in the manual is not same as HID input report.
Could you please kindly clarify?

Thanks and Regards

I think that this is a repeat of an open support tix. No? We're not sure what "read file()" is but please check out the user manual api steps. You just need to use an HID library to receive the DOA.. no need to pull anything.. Unfortunately we can't provide custom programming on this type of simple HID communication.. maybe ask a programmer locally to help you on HID library support?

I'm facing a similar problem here. I have a UMA8 and a UMA16 and neither of them appear to Windows when plugged in as HID. They both appear as 'miniDSP USB 2.0 Audio Devices' (class IDs {958b848b-9857-4d5e-b5b8-585d8c1d741e} and {a5dcbf10-6530-11d2-901f-00c04fb951ed}.

Any attempt to query them fails at the first hurdle when HidD_GetPreparsedData() fails with an unhelpful error code of EE000030.
