| Summary | 0006713: HID report - Vendor defined - Output only | ||||
| Description | Composite HID device with 3 joysticks and 1 vendor defined. Joysticks are read-only Vendor defined is 52 bytes write-only : | ||||
| Steps To Reproduce | Start demo project SimpleHIDWrite. At JvHidControllerClass.pas:567 then code "if Device.ReadFileEx(Report[0], Device.Caps.InputReportByteLength, @DummyReadCompletion) then" is called with Device.Caps.InputReportByteLength equal to 0. This raise error 0001784 | ||||
| Additional Information | I inserted before L567 the following test and the error 1784 is not raised anymore, but I don't know if this is the proper fix if (Device.Caps.InputReportByteLength > 0 ) then | ||||
| Tags | No tags attached. | ||||
