Summary	0005259: jvHidDeviceController HID devices don't work in delphi 2010
Description	The jvHidDeviceController component (in jvHidController.pas) doesn't work in delphi 2010. If you compile and run the standard examples that come with the component in the examples directory such as: BasicDemo and SimpleHIDWrite that work perfectly in delphi 7; they raise an exception when running.
Additional Information	I think it has something to do with incompatibility with the Unicode strings of Delphi 2010
Tags	No tags attached.

nehtek 2010-06-14 18:18 reporter ~0017492	The exception problem turned out to be from a multitouch screen; so when I disconnected the multitouch screen's usb cable; the exception dissapeared. But there is a difference in the received data between delphi 7 and Delphi 2010. I connected a Griffin PowerMate Knob and checked the data received in the SimpleHIDWrite example compiled first in Delphi7 and then Delphi2010; as you can see from the two screenshots I have attached; the data is not interpreted correctly.
